根據自己的需要可以將TEXMFHOME目錄設置成不同的地方，只要Latex能找到即可
我將該目錄改為了/usr/share/texmf-tetex,如果相應的目錄不存在，則需要自己新建。


將windows系統中的字體文件拷到腳本所在目錄執行腳本即可生成Latex所需字體文件，以simhei.ttf為例：

sudo ./cvtfont.sh simhei.ttf simhei simhei

Ubuntu下NVIDIA驅動的問題

前幾天按照Ubuntu How-To上的NVIDIA驅動安裝說明安裝了8672版的驅動，結果發現只要退出X-Window，系統就會沒有反應，網上搜了搜，發現有人也有一樣的情況，按照說明重新安裝、重新配置Xorg，問題依然沒有解決，X-Window也起不來了。

到NVIDIA網站上下了最新的8774版驅動后，趕緊找找看怎么自己裝，有人已經寫好了
在恢復模式下：
需要gcc支持，如果沒有安裝則：
apt-get install build-essential gcc
刪除已經安裝的NVIDIA驅動：
apt-get --purge remove linux-restricted-modules-`uname -r` linux-restricted-modules-common nvidia-glx nvidia-settings nvidia-kernel-common
安裝內核headers
apt-get install linux-headers-`uname -r`
將下載下來的NVIDIA-Linux-x86-1.0-8774-pkg1.run解壓縮：
sh ./NVIDIA-Linux-x86-1.0-8774-pkg1.run --extract-only
進入解壓后的NVIDIA-Linux-x86-1.0-8774-pkg1文件夾，執行安裝：
./nvidia-installer -n --x-prefix=/usr/lib/xorg/
最后由于默認安裝到了/usr/lib/xorg/lig/xorg，需要將文件拷到對應的目錄下：
cp --no-dereference /usr/lib/xorg/lib/xorg/libX* /usr/lib/xorg/modules/

cp /usr/lib/xorg/lib/xorg/modules/drivers/* /usr/lib/xorg/modules/drivers/

cp --no-dereference /usr/lib/xorg/lib/xorg/modules/extensions/* /usr/lib/xorg/modules/extensions/

Qt 4下連接MySQL數據庫

前天剛裝了個Qt4for windows，發現安裝的時候MySQL等數據庫插件都沒有安裝，像Qt X11版一樣，都需要自己安裝這些插件。

在Qt的安裝目錄C:\Qt4.1.2\下，有個src目錄，進入plugins\sqldrivers\mysql，可以看到兩個文件，main.cpp和mysql.pro,很顯然要用qmake來完成編譯、生成目標。

編譯前，首先保證依賴的MySQL頭文件和庫文件正確。首先MySQL安裝目錄下的include中的所有文件拷到qmake時能找到的目錄下，接著從lib/opt目錄下拷出libmysql.a,其實lib/opt下只有libmysql.lib和libmysql.dll，從網上搜了一下找到一個方法從libmysql.dll生成libmysql.a:

1 、安裝好MySQL （如果不愿意安裝，找個libmySQL.dll文件也可以）

2、下載Pexports工具

3、轉換操作： pexports libmysql.dll > libmysql.def

4、使用MinGW的 dlltool轉換成為libmysql.a文件。dlltool --input-def libmysql.def --dllname libmysql.dll --output-lib libmysql.a -k

5、嘗試是否成功：
將生成的libmysql.a 拷到qmake的lib搜索路徑下后在plugins\sqldrivers\mysql目錄下做：
qmake -project
qmake
make

如果再出現象mysql_connect@xx （xx是數字）的錯誤提示。就執行第6步。

6、修改libmysql.def文件，給mysql_connect加上@xx，即mysql_connect@xx

7、重做第4步

8、然后嘗試第5步，如果還是出現錯誤提示。就作第6步。一直到沒有錯誤為止。

最后C:\Qt4.1.2\plugins\sqldrivers下將會生成需要的libqsqlmysql.a和qsqlmysql.dll。

找了一個測試文件，通過。

#include?<QtSql>?

#include?<QtGui>?

bool?createConnection(){?

QSqlDatabase?db?=?QSqlDatabase::addDatabase("QMYSQL");?

db.setHostName("localhost");?

db.setDatabaseName("test");?

db.setUserName("test");?

db.setPassword("");?

if(!db.open()){?

QMessageBox::critical(0,?QObject::tr("Database?Error"),?

??????????????????????????????db.lastError().text());?

return?false;?

QSqlQuery?query;?

//query.exec("insert?into?book?values(?3,?'title',?'author')?");?

query.exec("select?title?,?author?from?book?");?

while?(query.next())?{?

????QString?title?=?query.value(0).toString();?

????QString?author?=?query.value(1).toString();?

QMessageBox::critical(0,?title,author);?

????

return?true;?

int?main(int?argc,char**?argv){?

QApplication?app(argc,?argv);?

????if?(!createConnection()){?

return?1;?

????????

????return?app.exec();?

SSH(Spring + Struts + Hibernate)小試之三

SSH(Spring + Struts + Hibernate)小試之三

前面通過PlugIn我們實現了Spring Context的加載，不過僅僅加載Context并沒有什么實際
意義，我們還需要修改配置，將Struts Action交給Spring容器進行管理。下面將通過一個Regsit
實例加以說明。

首先準備好regist.jsp和login.jsp,在regist.jsp中的form有name,password,password2,email域。

在struts-config.xml中添加配置：

<form-bean name="registForm" type="com.lzy.forum.form.RegistForm" />

<action path="/regist" name="registForm"
type="org.springframework.web.struts.DelegatingActionProxy"

validate="true" input="/regist.jsp" scope="request">
<forward name="failure" path="/regist.jsp" />
<forward name="success" path="/login.jsp" />
</action>

RegistForm,RegistAction按照原來Struts的方法去寫,我在RegistAction中加入了一個UserDAO對象
userDAO，這個對象由Spring注入。

<bean name="/regist" class="com.lzy.forum.action.RegistAction"
singleton="false">
<property name="userDAO">
<ref local="userDAO" />
</property>
</bean>

基本上SSH的架構已經完成，經確認后可以自己測試一下了。（完）

SSH(Spring + Struts + Hibernate)小試之二

Spring和Struts結合有幾種方法，我選了最常用的PlugIn方式，在struts-config.xml中加入

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
??????<set-property property="contextConfigLocation"
?????????? ?value="/WEB-INF/action-servlet.xml" />
?</plug-in>

WEB-INF目錄下的action-servlet.xml就是Spring的配置文件,下面給出的是整個的action-servlet.xml文件：

經過這樣的配置之后，Hibernate事務交由Spring管理，sessionFactory從Spring容器獲得。下面通過其中的一個DAO實例來看看這樣做帶來的方便。

//BoardDAO.java

package com.lzy.forum.dao;

import java.util.ArrayList;

import com.lzy.forum.domain.Board;

public interface BoardDAO {
?
?public boolean isBoardExist(String name);
?
?public void addBoard(Board board);
?
?public void deleteBoard(Board board);
?
?public Board loadBoard(int id);
?
?public Board loadBoard(String name);
?
?public Board loadBoardWithArticles(int id);
?
?public ArrayList getRootBoardsList();
?
?
?
}

//BoardDAOHibernate.java

package com.lzy.forum.dao.impl;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.ListIterator;
import java.util.Set;

import org.hibernate.Hibernate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.lzy.forum.dao.BoardDAO;
import com.lzy.forum.domain.Board;

public class BoardDAOHibernate extends HibernateDaoSupport implements BoardDAO {

?public void deleteBoard(Board board) {
??// TODO Auto-generated method stub
??this.getHibernateTemplate().delete(board);
?}

?public void addBoard(Board board) {
??// TODO Auto-generated method stub
??this.getHibernateTemplate().saveOrUpdate(board);

?public boolean isBoardExist(String name) {
??// TODO Auto-generated method stub
??ArrayList list = (ArrayList) this.getHibernateTemplate().find(
????"from Board where name = ? ", new Object[] { name });
??if (list.size() > 0) {
???// System.out.println("find it");
???return true;
??}
??return false;
?}

?public Board loadBoard(int id) {
??// TODO Auto-generated method stub
??ArrayList list = (ArrayList) this.getHibernateTemplate().find(
????"from Board where id = ? ", new Object[] { id });

??Board b = null;
??if (list.size() > 0) {
???b = (Board) list.get(0);
??}

??return b;
?}

?public Board loadBoard(String name) {
??// TODO Auto-generated method stub
??ArrayList list = (ArrayList) this.getHibernateTemplate().find(
????"from Board where name = ? ", new Object[] { name });

??Board b = null;
??if (list.size() > 0) {
???b = (Board) list.get(0);
??}

??return b;
?}

?public ArrayList getRootBoardsList() {
??// TODO Auto-generated method stub
??ArrayList list = (ArrayList) this.getHibernateTemplate().find(
????"from Board b left join fetch b.ChildBoards where b.Parent = null order by b.id");
??System.out.println(list.size() + " root boards found ");
??

??ListIterator index = list.listIterator();
??while (index.hasNext()) {

???Board s = (Board) index.next();
???//this.getSession(true);
???//Hibernate.initialize(s.getChildBoards());
???///*
??? Set children? = (Set) s.getChildBoards();
??? Iterator it = children.iterator();
???
??? while(it.hasNext()){
??? Board b = (Board)it.next();
??? //Hibernate.initialize(b);
??? System.out.println(b.getName());
??? }
??? //*/

???//System.out.println(children.size() + "child(ren) found ");
???//s.setChildBoards(s.getChildBoards());
??}

??return list;
?}

?public Board loadBoardWithArticles(int id) {
??// TODO Auto-generated method stub
??ArrayList list = (ArrayList) this.getHibernateTemplate().find(
????"from Board b left join fetch b.Articles where b.Id = ? ", new Object[] { id });

??Board b = null;
??if (list.size() > 0) {
???b = (Board) list.get(0);
??}

??return b;

?}

}

BoardDAOHibernate繼承 HibernateDaoSupport后，通過getHibernateTemplate()得到一個HibernateTemplate實例，然后執行CRUD操作，非常簡單。需要注意的是，由于執行一次CRUD操作后，Hibernate session關閉，如果有使用延遲加載策略的對象沒有加載，在后面的Web層很容易出現如下錯誤：
failed to lazily initialize a collection of role
從網上搜到的解決方法是Open Session In View，
<filter>
???? <filter-name>hibernateFilter</filter-name>
???? <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
???? </filter-class>

???? 
??? <init-param>
?????? <param-name>singleSession</param-name>
?????? <param-value>true</param-value>
??? </init-param>
? </filter>

?? <filter-mapping>
???? <filter-name>hibernateFilter</filter-name>
???? <url-pattern>*.do</url-pattern>
?? </filter-mapping>
我試了試，還是有一些問題，所以后來還是放棄了這種方法，所有在Web層中需要的對象都必須在Business層中加載完成。如下面的代碼所示：

ArrayList list = (ArrayList) this.getHibernateTemplate().find(
????"from Board b left join fetch b.Articles where b.Id = ? ", new Object[] { id });

這樣Hibernate和Spring的結合也算完成了。其他的一些DAO類和實現代碼我沒有給出，但是大同小異，和Board的實現類似。

最后將是Struts 和Spring的結合，將在下一篇給出。（未完待續）

SSH(Spring + Struts + Hibernate)小試之一

之前對Spring Struts Hibernate都稍有了解，Spring的IOC給我留下了很深的印象，容器管理的對象生成
方法極大地簡化了程序邏輯，Spring也提供了用于Web的Spring MVC 框架，由于我感覺其易用性還是不及
Struts，所以我還是選擇Struts作為前端WEB框架，Hibernate我一直沒有在Web應用中試過，這次當然不會
錯過機會了。

開發環境的塔建我就不多說了，具體可以參考我以前的幾篇日志。

在Eclipse中新建一個動態Web工程，將Struts 、Spring、Hibernate需要的jar都添加到WEB-INF/lib目錄下，
將Struts標簽所需的tld文件、struts-config.xml文件（可以由StrutsIDE生成）添加到WEB-INF下，另外在
此目錄下添加一個Spring的配置文件applicationContext.xml。

我參考的例子是夏昕的《深入淺出Hibernate》上的第6章，很好的一個論壇示例。

首先按照書上的ER模型，在數據庫（MySQL）中建立相應的數據庫。

create database forum;

use forum;

create table user(
?id int not null auto_increment primary key,
?name varchar(50),
?pwd varchar(50),
?email varchar(50)

)type=innodb;

create table board(
?id int not null auto_increment primary key,?
?parent_id int,
?create_by int not null,
?name varchar(50) not null,
?remark varchar(255),
?create_time datetime,

?index(parent_id),
?index(create_by),

?foreign key(parent_id) references board(id) on delete cascade,
?foreign key(create_by) references user(id) on delete no action
?
)type=innodb;

create table article(
?id int not null auto_increment primary key,?
?parent_id int ,
?board_id int not null,
?article_type int not null,
?title varchar(255),
?body text,
?create_by int not null,

?create_time datetime,
?hits int unsigned,
?bytes int unsigned,
?last_update_by int not null,
?last_update_time datetime,

?index(parent_id),
?index(board_id),
?index(create_by),
?index(last_update_by),

?foreign key(parent_id) references article(id) on delete no action,

之后，我選擇了用Hibernate Sychonizer來生成映射文件和實體類，然后對生成的類進行修改（刪掉了生成的Base類），
實際上Hibernate Sychonizer生成的映射文件也有錯誤，需要修改，我也是后來在使用中發現的。

Eclipse + CDT + MinGW 下編寫QT程序

環境：
（1）安裝Eclipse + CDT + MinGW
（2）安裝QT for Windows
（3）安裝QT plugin for Eclipse ：org.eclipse.qt-1.0.2.zip，在Preference里設好相關路徑。

新建一個 QT project，將hello。cpp復制到工程中：
#include <QApplication>
#include <QPushButton>

int main(int argc, char *argv[]){
?
?QApplication app(argc, argv);
?
?QPushButton hello("Hello world!");
?
?hello.resize(100, 30);
?hello.show();
?
?return app.exec();
}

build后生成Makefile，新建兩個Make Target:all,clean
Make all 后發現找不到libQtCored4.a等文件，在QT的lib目錄下找到相應的libQtCore4.a，復制后重命名為libQtCored4.a，
其他庫文件類似，最后編譯通過，運行后出現帶hello按鈕的窗口。

Eclipse + CDT + MinGW 下編寫OpenGL程序

Eclipse + CDT + MinGW環境的搭建比較簡單，由于機器內存不夠大，我在preference里將C＋＋的indexer都置為NO INDEXER。
安裝MinGW后可以看到，在Include和Lib目錄下有了與OpenGL相關的頭文件和靜態庫。為了使用GLUT,我將glut.h放到了相應的
GL目錄下，看到Lib目錄下有libglut.a庫文件，我沒有將glut。lib放進去（后來發現libglut。a好像在windows不可用）。

新建一個Standtart Make C++ project,將原來可運行的OpenGL程序復制過來，寫好Makefile，結果編譯的時候還是出現錯誤。
還好找到了這個非常有用的網頁：http://www.mingw.org/MinGWiki/index.php/Glut
按照上面列出的錯誤，我在每個＃include<GL/glut.h>前都加上#define _STDCALL_SUPPORTED，然后又將glut32。lib、
opengl32.lib、glu32.lib都放到當前的工程目錄下，用”glut32。lib opengl32.lib glu32.lib“ 代替原來的 ”-lglut -lopengl32 -lglu32",
最后終于編譯通過。

JavaScript和Applet互相調用

Java Script 調用 java 可以在網頁里使用

?????? document.applet_name.method_name();

</script>

可以對 applet 進行控制，也可以從 applet 返回值。

Java 調用 Java Script

需要導入 netscape.javascript.jsobject 這個類（jre/lib/plugin.jar)

比如：

JSObject window=JSObject.getWindow(this);

JSObject window=(JSObject)window.getMember("document");

來獲取對當前窗口的控制權。

當點擊鏈接 MakeCall 時，會觸發 Java Script 函數

function makeCall(s){

? window.document.ctiApplet.testJavascript(s);

? alert("call maked!");

在這個 Java Script 函數中， ctiApplet 是一個 Applet ，這樣完成了 java script 調用

Applet 。

以下是 ctiApplet 中的 testJavascript 函數和運行結果，其中又調用了 Java Script 。
public void testJavascript(String msg){

??????

?????? try {

????????????? // create JSObject

?????? ??? ?????? JSObject.getWindow (this).eval ("javascript:alert('Java Script in Applet!')") ;

?????? }

?????? catch (Exception ex) {

????????????? // Error on create JSObject

?????? ??? ?????? showStatus( "Error call javascript err=" + ex );

?????? }

?????? System.out.println(msg);

}

EJB 3.0 學習筆記——準備工作

在開發EJB3.0 之前，首先應該去下載它的一個實現和一個相應的支持EJB3的服務器，我下載的是jboss-EJB-3.0_RC5-PFD和JBoss 4.0.3SP1 ，jboss-EJB-3.0_RC5-PFD里面有安裝說明和一些不錯的tutorial。

根據安裝說明，JBoss 4.0.3SP1中的EJB3實現不是最新的，應用下載的jboss-EJB-3.0_RC5-PFD中的一些包去替換。

將jboss-EJB-3.0_RC5-PFD中lib目錄下的
?(1)ejb3.deployer/
?(2)ejb3-clustered-sfsbcache-service.xml
?(3)ejb3-interceptors-aop.xml
?(4)jboss-aop-jdk50.deployer/
拷貝到jboss-4.0.3SP1/server/all/deploy目錄下

將jboss-EJB-3.0_RC5-PFD中lib目錄下的
?(5)jboss-remoting.jar
?(6)jboss-serialization.jar
?(7)jboss-j2ee.jar
拷貝到jboss-4.0.3SP1/server/all/lib目錄下

刪除jboss-4.0.3SP1/server/all/lib 下的
?(1)ejb3-persistence.jar
?(2)hibernate3.jar
?(3)hibernate-annotations.jar
?(4)hibernate-entitymanager.jar
和jboss-4.0.3SP1/server/all/deploy下的
?(5)jboss-aop.deployer/
到此EJB3 的運行環境準備好了，你可以用jboss-4.0.3SP1\bin\run -c all 測試JBoss是否能成功啟動。

我用的IDE是Eclipse 3.2，JDK 1.5 ，為了方便在Eclipse中新建一個User Library：EJB3_JBoss，
將jboss-EJB-3.0_RC5-PFD\lib下的
?jboss-j2ee.jar
和jboss-EJB-3.0_RC5-PFD\lib\ejb3.deployer下的
?ejb3-persistence.jar
?jboss-ejb3x.jar
?jboss-ejb3.jar
?jboss-annotations-ejb3.jar
?hibernate3.jar
?hibernate-annotations.jar
?hibernate-entitymanager.jar
添加到EJB_JBoss中，現在環境基本上搭好了。

FreeBSD 5.3 中的聲卡問題

在FreeBSD 5.x中，kernel配置文件的設備名改為sound，不是FreeBSD 4.x中的pcm了，以后還有可能改為snd。

#cd /usr/src/sys/i386/conf/
#make LINT
可生成LINT文件，將kernel配置里的項全部列出了。

在kernel配置文件里加上
device sound
device snd_foo 或
device "snd_foo" <----注意這里foo表示不同的聲卡種類，可參考LINT文件。

如果不知道你的聲卡應該用哪一個，可以先用
#kldload snd_driver 將所有常用的聲卡驅動裝載，然后用

#cat /dev/sndstat 察看是否有相應的聲卡信息，如：
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: at io 0xd800, 0xdc80 irq 5 bufsz 16384
kld snd_ich (1p/2r/0v channels duplex default)

這里snd_inc就是對應的應該裝載的設備。

注意如果對應的聲卡種類中有數字，就應該加上引號。

這樣重新編譯內核就可以了。當然如果不編譯內核，用load module的方式也可以。

那么我的問題是什么呢？我用
#dmesg|grep pcm 能察看到聲卡信息。
用 #cat /dev/sndstat 也能看到正確的聲卡信息。
并且能夠播放CD，但是使用xmms等軟件播放mp3文件的時候，播放條根本不走。而后從dmesg可看到如下信息:

pcm0:play:0: play interrupt timeout, channel dead

經過Google查詢，懷疑問題出在系統ICQ沖突上。最后，在啟動FreeBSD　5.3時，選擇了ACPI Disable，就能夠正確地用xmms播放了。

最后補充以下，我的機器安裝了兩塊網卡，一塊SCSI卡。使用的是版載聲卡。怎么解決在ACPI情況下使用還不清楚。但問題基本確定的確是ICQ資源的問題。

FreeBSD安裝問題及漢化

五一這幾天沒事閑的裝了FreeBSD,時間可沒少花,問題卻還是不少,也許對系統還不是太熟悉吧.

1.USB鼠標的問題

第一次裝的時候,測試鼠標的時候沒動靜,不知當時是不是鼠標沒插好
只好用PS/2口了,后來編譯了一遍內核,USB才能用.

然而最后一次裝的時候,USB口可以用,但是startx進入KDE的時候總是失敗,找不到什么Pointer,將鼠標插入
PS/2口后重啟,上述現象又沒了,感覺很是奇怪,進入kde后將鼠標插入USB口也正常.

2..xinitrc文件的問題

第一次裝的時候是按照書上裝的,當時把xinitrc文件復制過來

cp /usr/X11R6/lib/X11/xinitrc/xinitrc /root/.xinitrc

3.中文字體和輸入法

首先安裝cvsup,更新ports,然后安裝kde-zh******,之后就可以看到kde的一些界面已經中文化了,但是還是有亂碼,弄個中文字體過來就可以了

將windows中的simsun.ttc改名為simsun.ttf后復制到/usr/X11R6/lib/X11/fonts/TTF中,然后運行命令

fc-cache -f -v就可以了

中文輸入法很簡單.fcitx,不過以前裝的時候沒有更新ports時好象不行.

JSP 處理MySQL數據庫時的中文問題

以前遇到JSP 處理MySQL數據庫時的中文問題時，采取的是很笨的一種方法，直接用字符串編碼轉換函數進行轉換，這次從網上搜了一下，找到了一個使用Filter的可行方法。在Tomcat 5.5＋ MySQL4.0.16下通過。

filter類源碼是從網上找的，如下
/**
*
*/
package com.lzy;

import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**
* @author lzy
*
*/
public class SetCharacterEncodingFilter implements Filter {

protected String encoding = null;
protected FilterConfig filterConfig = null;
protected boolean ignore = true;

/* (non-Javadoc)
* @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
*/
public void init(FilterConfig filterConfig) throws ServletException {
  // TODO Auto-generated method stub
  this.filterConfig = filterConfig;
     this.encoding = filterConfig.getInitParameter("encoding");
     String value = filterConfig.getInitParameter("ignore");
     if (value == null)
     this.ignore = true;
     else if (value.equalsIgnoreCase("true"))
     this.ignore = true;
     else if (value.equalsIgnoreCase("yes"))
     this.ignore = true;
     else
     this.ignore = false;

}

/* (non-Javadoc)
* @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)
*/
public void doFilter(ServletRequest request, ServletResponse response,
   FilterChain chain) throws IOException, ServletException {

  // TODO Auto-generated method stub
  if (ignore || (request.getCharacterEncoding() == null)) {
   String encoding = selectEncoding(request);
   if (encoding != null)
    request.setCharacterEncoding(encoding);
  }
  chain.doFilter(request, response);
}

/* (non-Javadoc)
* @see javax.servlet.Filter#destroy()
*/
public void destroy() {
  // TODO Auto-generated method stub

  this.encoding = null;
     this.filterConfig = null;

}

protected String selectEncoding(ServletRequest request) {

return (this.encoding);

}

在web.xml 文件中作如下設置：（我使用的是Struts框架）
<filter>
<filter-name>Encoding</filter-name>
<filter-class>com.lzy.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>Encoding</filter-name>
<servlet-name>action</servlet-name>
</filter-mapping>
<filter-mapping>
<filter-name>Encoding</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>

最后，連接數據庫時，使用下面的url：
jdbc:mysql://localhost:3306/數據庫名?useUnicode=true&characterEncoding=GBK

Spring之Hello World

1.下載Spring相關的開發包
下載地址：http://sourceforge.net/project/showfiles.php?group_id=73357
有spring-framework-1.2.6-with-dependencies.zip，一個是spring-framework-1.2.6.zip，最好下載with－dependencies的，里面有另外一些附加包，下載后解壓縮，dist目錄下是spring自身的jar，lib目錄下是附加的jar。
2.新建Java Project，將spring.jar（dist目錄下）和commons-logging.jar（lib目錄下）添加到project的build path中。
3.新建POJO Bean類：HelloBean
//HelloBean.java
/**
*
*/
package com.lzy;

/**
* @author lzy
*
*/
public class HelloBean{

private String hello;

public void sayHello(){
System.out.println(this.getHello());
}

/**
* @return Returns the hello.
*/
public String getHello() {
return hello;
}

/**
* @param hello The hello to set.
*/
public void setHello(String hello) {
this.hello = hello;
}

}

4.新建文件bean.xml，將在這個XML文件中為一個HelloBean的實例的hello屬性賦值。
//bean.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "<beans>
<description>Spring Quick Start</description>
<bean id="helloBean" class="com.lzy.HelloBean">
  <property name="hello">
   <value>hello world</value>
  </property>
</bean>
</beans>

5.新建測試類：TestSpring
//TestSpring.java
/**
*
*/
package com.lzy;

import java.util.Locale;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

/**
* @author lzy
*
*/
public class TestSpring {

/**
* @param args
*/
public static void main(String[] args) {
  // TODO Auto-generated method stub

  ApplicationContext ctx=new FileSystemXmlApplicationContext("bean.xml");
    HelloBean hello=(HelloBean)ctx.getBean("helloBean");
  hello.sayHello();
}

}

6.運行測試類：
如果沒有出錯，輸出中將會看到“hello world”。

Eclipse下Hibernate入門

1.開發環境
     Eclipse 3.2＋MySQL 4.0.16＋Hibernate3.0
    首先應該安裝好Eclipse和MySQL，此外準備好MySQL的JDBC Driver和Hibernate3.0,相關下載地址如下：
     Eclipse SDK：
        http://www.eclipse.org/downloads/index.php
       MySQL及MySQL的JDBC Driver:
           http://www.mysql.org
       Hibernate:
          http://www.hibernate.org
       此外我還安裝了Eclipse的一個Hibernate插件：
     Hibernate synchronizer
           http://hibernatesynch.sourceforge.net

Plugin Search:
http://eclipse-plugins.2y.net/eclipse/search.jsp

Hibernate synchronizer插件的安裝和配置有問題請直接Google。

在工程中其實只用到了Hibernate synchronizer插件的一部分功能，Hibernate依賴的相關jar包最好還是手動添加，因為最開始用Hibernate synchronizer添加時總是發生錯誤。
將下載的Mysql driver和Hibernate包解壓縮，我們需要的只是里面相關的jar，在Eclipse中新建Mysql_Driver和Hibernate兩個user library,將mysql-connector-java-3.0.15-ga-bin.jar加入Mysql_Driver中，將hibernate3.jar，
，log4j-1.2.11.jar，antlr-2.7.5H3.jar，asm.jar，asm-attrs.jar，cglib-2.1.2.jar，commons-collections-2.1.1.jar，commons-logging-1.0.4.jar，dom4j-1.6.1.jar，ehcache-1.1.jar，jta.jar加入到Hibernate中。

2.開始
在Mysql中新建test數據庫（Mysql其實有個空的test數據庫），然后新建下面的Table

create table user (
id int(10) not null auto_increment primary key,
name varchar(20) not null,
password varchar(20) not null,
email varchar(50),
address varchar(100)
)type=innodb;

新建Java Project，將Mysql_Driver,Hibernate兩個user library添加到該工程的java build path中。

新建與數據表對應的POJO類：User和Contact

/**
*
*
*/
package com.user;

/**
* @author lzy
*
*/
public class User{
    private Integer id;
    private String name;
    private String password;
    private Contact contact;

/**
* @return Returns the id.
*/
public Integer getId() {
  return id;
}
/**
* @param id The id to set.
*/
public void setId(Integer id) {
  this.id = id;
}
/**
* @return Returns the name.
*/
public String getName() {
  return name;
}
/**
* @param name The name to set.
*/
public void setName(String name) {
  this.name = name;
}
/**
* @return Returns the password.
*/
public String getPassword() {
  return password;
}
/**
* @param password The password to set.
*/
public void setPassword(String password) {
  this.password = password;
}
/**
* @return Returns the contact.
*/
public Contact getContact() {
  return contact;
}
/**
* @param contact The contact to set.
*/
public void setContact(Contact contact) {
  this.contact = contact;
}


}
/**
*
*/
package com.user;

/**
* @author lzy
*
*/
public class Contact {
private String email;
private String address;

/**
* @return Returns the address.
*/
public String getAddress() {
  return address;
}
/**
* @param address The address to set.
*/
public void setAddress(String address) {
  this.address = address;
}
/**
* @return Returns the email.
*/
public String getEmail() {
  return email;
}
/**
* @param email The email to set.
*/
public void setEmail(String email) {
  this.email = email;
}
}

之后可以用synchronizer插件生成Hibernate配置文件和映射文件（相關過程可以參考http://www.ideagrace.com/html/doc/2005/08/01/00315.html)，不過映射文件必須稍作修改。

hibernate.cfg.xml
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"

<hibernate-configuration>
<session-factory >

<property name="hibernate.connection.url">jdbc:mysql://localhost/test</property>
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.connection.username"></property>
  <property name="hibernate.connection.password"></property>

<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <property name="hibernate.show_sql">True</property>
        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
    <mapping resource="User.hbm.xml"/>

</session-factory>
</hibernate-configuration>

User.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"

<hibernate-mapping package="com.user">
<class
  name="User"
  table="user"
>
  <id
   name="Id"
   type="integer"
   column="id"
  >
   <generator class="native"/>
  </id>

</class>
</hibernate-mapping>

3.測試
添加一個測試類：HibernateTest

package com.user;

import java.util.List;
import java.util.ListIterator;

import org.hibernate.*;
import org.hibernate.cfg.*;

public class HibernateTest {
    public static void main(String[] args) throws HibernateException {
        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

        //
        //testInsert(sessionFactory);

        //
        testQuery(sessionFactory);


        sessionFactory.close();

    }
    public static void testInsert( SessionFactory sessionFactory )throws HibernateException {

   Session session = sessionFactory.openSession();
        Transaction tx= session.beginTransaction();
        User user = new User();
        Contact contact=new Contact();
        contact.setEmail("email");
        contact.setAddress("address");

        user.setName("caterpillar");
        user.setPassword("password");
        user.setContact(contact);

        session.save(user);
        tx.commit();
        session.close();
        System.out.println("OK！");
}

    public static void testQuery( SessionFactory sessionFactory )throws HibernateException {

    Session session = sessionFactory.openSession();
        Transaction tx= session.beginTransaction();
        User user = new User();
        Contact contact=new Contact();

        Query query=session.createQuery("from User as user");
        //query.setCharacter(1, 'M');
        List names =query.list();
        for(ListIterator it=names.listIterator();it.hasNext();){
          user= (User)it.next();
          System.out.println("Id: " + user.getId());
            System.out.println("name: " + user.getName());
            System.out.println("password: " + user.getPassword());
            if(user.getContact()!=null){

            if(user.getContact().getEmail()!=null){
              System.out.println("Email: " + user.getContact().getEmail());
            }
            if(user.getContact().getAddress()!=null){
              System.out.println("Address: " + user.getContact().getAddress());

            }
            }



        }


        tx.commit();
        session.close();

    }
}

Eclipse下JSF入門

1.開發環境
與Eclipse下Struts的開發類似，安裝好Eclipse和Tomcat之后，還需要兩個插件：tomcat 插件和JSF插件（如果相關插件還沒有安裝），以下是相關下載地址：
Eclipse SDK：
http://www.eclipse.org/downloads/index.php
JSF:
https://sourceforge.jp/projects/amateras/files/
FaceIDE+htmlEditor，htmlEditer也是必要的
Tomcat :
http://www.sysdeo.com/eclipse/tomcatplugin
Plugin Search:
http://eclipse-plugins.2y.net/eclipse/search.jsp
插件的安裝和配置有問題請直接Google。
2.開始
入門嘛，我們就找一個最簡單的Login就可以了

新建Tomcat project
加入JSF支持

新建一個ManagedBean：

/**
*
*/
package com.jsf;

/**
* @author lzy
*
*/
public class UserBean {
private String name;
private String password;
public String verify() {
if(this.name.equals("name")&&this.password.equals("password"))

return "failure";

else
return "success";
}

/**
* @return Returns the name.
*/
public String getName() {
return name;
}

/**
* @param name The name to set.
*/
public void setName(String name) {
this.name = name;
}

/**
* @return Returns the password.
*/
public String getPassword() {
return password;
}

/**
* @param password The password to set.
*/
public void setPassword(String password) {
this.password = password;
}

}

新建兩個JSP頁面，login.jsp,welcom.jsp

login.jsp
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<html>
<head>
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<html>
<head>
<link href="main.css" rel="stylesheet"/>
<title></title>

</head>
<body>
<f:view>
<f:loadBundle basename="com.jsf.MessageResources" var="msgs"></f:loadBundle>

<h:form>
<h:panelGrid columns="3" headerClass="header" rowClasses="evenRow,oddRow">
<f:facet name="header" >
<h:outputText value="#{msgs.header}"/>
</f:facet>

<h:outputText value="#{msgs.namePromt}"></h:outputText>
<h:inputText id="name" required="true" value="#{user.name}">
<f:validateLength minimum="2" maximum="10"></f:validateLength>
</h:inputText>
<h:message for="name" errorClass="errors"/>

<h:outputText value="#{msgs.passwordPromt}"></h:outputText>

<h:inputSecret id="password" value="#{user.password}" required="true" redisplay="true">
<f:validateLength minimum="2"></f:validateLength>
</h:inputSecret>
<h:message for="password"/>

<f:facet name="footer" >
<h:outputText value="#{msgs.footer}"/>
</f:facet>
</h:panelGrid>
<h:commandButton value="#{msgs.submitPromt}" action="#{user.verify}"/>
<h:commandButton value="#{msgs.resetPromt}" type="reset"/>
</h:form>
</f:view>
</body>
</html>

welcome.jsp

<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK"/>
<title></title>
</head>
<body>
<f:view>
<h:outputText value="#{user.name}"/> is a good boy！
<h3>welcome JavaServer Faces</h3>
</f:view>
</body>

</html>
編輯WEB－INF/lib下的faces－config.xml

struts-config.xml

<?xml version="1.0"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config>
<navigation-rule>
<from-view-id>/login.jsp</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/welcome.jsp</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>failure</from-outcome>
<to-view-id>/login.jsp</to-view-id>
</navigation-case>
</navigation-rule>

<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>com.jsf.UserBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
</faces-config>

最后是資源文件

# --login.jsp--
header=Welcom
namePromt=Name:
passwordPromt=Password:
amountPromt=Amount:
datePromt=Date:
submitPromt=Submit
resetPromt=Reset
footer=Thank you!

3.測試
在test工程中選擇tomcat project－>Update context definition
然后運行Tomcat
http://127.0.0.1:8080/jsfTest/login.jsf

Eclipse下Struts開發入門

1.開發環境
   開發之前首先應該準備好開發環境，Eclipse 3.X是一個不錯的Java IDE，有很多插件可以供我們選擇，服務器用Tomcat就行了。安裝好Eclipse和Tomcat之后，還需要兩個插件：tomcat 插件和Struts插件，以下是相關下載地址：
     Eclipse SDK：
        http://www.eclipse.org/downloads/index.php
    Struts:
     https://sourceforge.jp/projects/amateras/files/         StrutsIDE+htmlEditor，htmlEditer也是必要的
    Tomcat :
         http://www.sysdeo.com/eclipse/tomcatplugin
    Plugin Search:
         http://eclipse-plugins.2y.net/eclipse/search.jsp
   插件的安裝和配置有問題請直接Google。
2.開始
    入門嘛，我們就找一個最簡單的Login就可以了

新建Tomcat project，如下圖

加入struts支持
新建一個FormBean:LoginForm

/**
*
*/
package com.test;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

/**
* @author lzy
*
*/
public class LoginForm extends ActionForm {

private String name=null;
private String password=null;
/* (non-Javadoc)
* @see org.apache.struts.action.ActionForm#reset(org.apache.struts.action.ActionMapping, javax.servlet.http.HttpServletRequest)
*/
@Override
public void reset(ActionMapping arg0, HttpServletRequest arg1) {
  // TODO Auto-generated method stub
  name=null;
  password=null;
}
/* (non-Javadoc)
* @see org.apache.struts.action.ActionForm#validate(org.apache.struts.action.ActionMapping, javax.servlet.http.HttpServletRequest)
*/
@Override
public ActionErrors validate(ActionMapping arg0, HttpServletRequest arg1) {
  // TODO Auto-generated method stub
ActionErrors errors=new ActionErrors();

  if(name==null||name.length()<1){
   errors.add("username",new ActionMessage("errors.login.name.empty"));

  }
  if(password==null||password.length()<1){
   errors.add("password",new ActionMessage("errors.login.password.empty"));

  }

  return errors;
}
/**
* @return Returns the name.
*/
public String getName() {
  return name;
}
/**
* @param name The name to set.
*/
public void setName(String name) {
  this.name = name;
}
/**
* @return Returns the password.
*/
public String getPassword() {
  return password;
}
/**
* @param password The password to set.
*/
public void setPassword(String password) {
  this.password = password;
}
}

新建一個Action:LoginAction

/**
*
*/
package com.test;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.apache.struts.*;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
import org.apache.struts.action.ActionMessages;

/**
* @author lzy
*
*/
public class LoginAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm actionForm, HttpServletRequest request, HttpServletResponse response) throws Exception {
  // TODO Auto-generated method stub
  LoginForm loginForm=(LoginForm)actionForm;
  String name=loginForm.getName();
  String password=loginForm.getPassword();

if(name.equals("name")&&password.equals("password")){
HttpSession session=request.getSession(true);
session.setAttribute("LOGGED_USER",name);

   return mapping.findForward("success");

  }
  else{
   ActionMessages errors=new ActionMessages();
   errors.add("login.failure",new ActionMessage("errors.login.failure"));
   this.saveErrors(request,errors);

   return mapping.findForward("failure");

  }

}

}

新建兩個JSP頁面，login.jsp,index.jsp

login.jsp
<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-tiles" prefix="tiles" %>

<html:html>
<head>
  <html:base />
          </head>
<body>
<center>
<html:errors />
  <html:form action="/login.do" method="POST">
  <table border="1">
   <tr>
    <td colspan="2"><bean:message key="login.jsp.form.title"/></td>
   </tr>
   <tr>
    <td align="right"><bean:message key="login.jsp.name"/></td>
    <td><html:text property="name" size="20"></html:text></td>
   </tr>
   <tr>
    <td align="right"><bean:message key="login.jsp.password"/></td>
    <td><html:password property="password" size="20"></html:password></td>
   </tr>
   <tr>
    <td colspan="2">
     <html:submit><bean:message key="form.submit"/></html:submit>
     <html:reset><bean:message key="form.reset"/></html:reset>
    </td>
   </tr>

  </table>

  </html:form>

</center>
</body>
</html:html>

index.jsp

<%@ page contentType="text/html; charset=GBK" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-nested" prefix="nested" %>

<html:html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=GBK"/>
  <title></title>
</head>
<body>
hello
  <logic:present name="LOGGED_USER">,<bean:write name="LOGGED_USER"/>
  </logic:present>
</body>
</html:html>

編輯WEB－INF/lib下的struts－config.xml

struts-config.xml

<?xml version="1.0"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "<struts-config>
<data-sources>
</data-sources>
<form-beans>
    <form-bean name="loginForm" type="com.lzy.LoginForm"/>
</form-beans>
<global-exceptions>
</global-exceptions>
<global-forwards>
</global-forwards>
<action-mappings>
      <action path="/login" name="loginForm" type="com.lzy.LoginAction" scope="session" validate="true" input="/login.jsp">
      <forward name="failure" path="/login.jsp"/>
      <forward name="success" path="/index.jsp"/>
    </action>
</action-mappings>
<controller processorClass="org.apache.struts.tiles.TilesRequestProcessor"/>
<message-resources parameter="MessageResources"/>

</struts-config>

最后是資源文件

# -- standard errors --
errors.header=<UL><font color="red"><h2>Errors:</h2>
errors.prefix=<LI>
errors.suffix=</LI>
errors.footer=</font></UL><hr>

form.submit=Submit

form.reset=Reset

# -- login.jsp --
login.jsp.title=Login
login.jsp.form.title=Login
login.jsp.name=Name:
login.jsp.password=Password:

# -- login errors --
errors.login.name.empty=The name can not be empty!
errors.login.password.empty=The password can not be empty!
errors.login.failure=Login failed!<br> Please check your username and password!

3.測試
在test工程中選擇tomcat project－>Update context definition
然后運行Tomcat
http://127.0.0.1:8080/test/login.jsp
