<h:outputText value="主題：#{index.appinfo.maxdocsum} value里不能加入HTML代碼但可以加入EL" />

序.畫流程圖.
一.創(chuàng)建數(shù)據(jù)庫.
注:
1.數(shù)據(jù)庫中設(shè)計(jì)INT(java.lang.Interger),  VARCHAR(N)(java.lang.String),  DATE(java.lang.Date)
2.1:N的情況下, 數(shù)據(jù)庫中設(shè)計(jì)外鍵(N方)和集合(一方).
2.hibernate 返向工程.

二.添加JSF, Spring, Hibernate 庫引用.
Spring 添加如下：



三. 為spring 配置 web.xml 和 faces-config.xml .
(1)web.xml
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>/WEB-INF/applicationContext.xml</param-value>
 </context-param>

(2)web.xml
<listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>              //Servlet API 2.3以后
或:
 <servlet>
  <servlet-name>context</servlet-name>
  <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
 </servlet>

(3)faces-config.xml
<application>
<variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>
</application>

(4)設(shè)置過濾器,解決亂碼問題
詳見:http://www.tkk7.com/algz/articles/201833.html 第二條

以上配置完成后.JSF就可以訪問SPRING管理的BEAN.

四.spring+hiberante集成時(shí),asm-2.2.3.jar與asm.jar沖突:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'SessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V  
...
Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V

正確的解決方法:
是到項(xiàng)目的發(fā)布文件夾\WEB-INF\lib下刪除asm-2.2.3.jar,不能用MyEclipse里刪除.因?yàn)樗诎l(fā)布時(shí)仍沒刪除.

五.創(chuàng)建進(jìn)行分類的包.
com.dao(數(shù)據(jù)訪問層), com.service(業(yè)務(wù)層), com.web(表示層)

六.創(chuàng)建類.(完成MODEL層設(shè)計(jì)).

  (一)數(shù)據(jù)訪問層(DAO)開發(fā): 

         Spring 配置文件（附加） 
           (1)配置數(shù)據(jù)源          <bean id="dataSource" ...>      //Myeclipse Hibernate自動(dòng)反轉(zhuǎn)工具自動(dòng)配置
           (2)配置會(huì)話工廠     <bean id="sessionFactory" ...>  //Myeclipse Hibernate自動(dòng)反轉(zhuǎn)工具自動(dòng)配置
           (3)配置事務(wù)管理器  <bean id="transactionManager" ...>
           (4)配置事務(wù)代理      www.tkk7.com/algz/articles/163236.html
           (5)數(shù)據(jù)訪問層Bean作為屬性注入業(yè)務(wù)層Property中. (注:不要用NEW創(chuàng)建數(shù)據(jù)訪問層對象,否則得不到ServletContext而報(bào)錯(cuò).)
例:
/**數(shù)據(jù)訪問層Bean（Myeclipse Hibernate自動(dòng)反轉(zhuǎn)工具配置）*/
 <bean id="userDao" class="com.data.dao.impl.UserDaoImpl">
  <property name="sessionFactory">
   <ref local="sessionFactory" />
  </property>
 </bean>

 /**業(yè)務(wù)層Bean（Myeclipse Spring配置文檔中可以配置，但需先定義好相關(guān)類）*/
 <bean id="userService" class="com.model.service.impl.UserServiceImpl">
  <property name="userDao">
   <ref bean="userDao" />
  </property>
 </bean>

        1. 創(chuàng)建 數(shù)據(jù)訪問層接口:    必須創(chuàng)建,詳見:http://www.tkk7.com/algz/articles/262893.html
            public interface 數(shù)據(jù)訪問層接口 {   //在類已存在的情況下,添加其接口:Refactor(重構(gòu)）->Extract Interfaces提取接口
                public String add...();
                public String save...();
                  ......                                            //update, delete, load
            }

        2 .創(chuàng)建數(shù)據(jù)訪問層實(shí)現(xiàn)類    //ORM反向功能自動(dòng)配置
            public class 數(shù)據(jù)訪問層實(shí)現(xiàn)類 extends HibernateDaoSupport implements 數(shù)據(jù)訪問層接口 {
            ......                                          //getHibernateTemplate().save(user)
            }
             在實(shí)現(xiàn)類的方法(throw DataAccessException)中封裝 getHibernateTemplate().save(user) 等Spring已封裝的持久化方法.(注:如果使用Hibernate API 要用try{...}catch{...}自行處理導(dǎo)常.)         

        3.注意事項(xiàng): could not initialize proxy - no Session 異常,  可能是沒有聯(lián)表查詢.詳見: http://www.tkk7.com/algz/articles/191835.html


*****************************(也可以利用MyEclipse反向ORM功能自動(dòng)產(chǎn)生)***********************************

   (二)業(yè)務(wù)邏輯層(Service)開發(fā):
         1.創(chuàng)建業(yè)務(wù)邏輯層接口. 
package com.service;
import com.dao.CheckDAO;
public interface ICheckService {
    public abstract CheckDAO getCheckDAO();
    public abstract void setCheckDAO(CheckDAO checkDAO);
    public abstract String searchCheck();
}

         2.創(chuàng)建業(yè)務(wù)邏輯層實(shí)現(xiàn)類 
             public class 業(yè)務(wù)邏輯層實(shí)現(xiàn)類 implements 業(yè)務(wù)邏輯層接口.
             在實(shí)現(xiàn)類中. 引用的數(shù)據(jù)訪問層對象實(shí)例采用DI的設(shè)值方式注入
                                   在業(yè)務(wù)邏輯方法(throw DataAccessException)中,使用數(shù)據(jù)訪問層對象實(shí)例來訪問數(shù)據(jù)庫.  
package com.service;
import java.util.List;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import com.dao.Check;
import com.dao.CheckDAO;
import com.dao.ICheckDAO;

public class CheckService implements ICheckService {
private CheckDAO checkDAO;

public CheckDAO getCheckDAO() {
 return checkDAO;
}

public void setCheckDAO(CheckDAO checkDAO) {
 this.checkDAO = checkDAO;
}

public String searchCheck(){
 List<Check> l=checkDAO.findAll();
 JSONArray ja=new JSONArray();
 JSONObject jo=new JSONObject();
for(Check c:l){
//  jo.put("department", c.getDepartment());
//  jo.put("checkid", c.getCheckid());
//  jo.put("nam", c.getNam());
//  jo.put("num", c.getNum());
//  jo.put("ondutytime", c.getOndutytime());
//  jo.put("offdutytime", c.getOffdutytime1());
//  jo.put("registerdate", c.getRegisterdate());
//  jo.put("overtime", c.getOvertime());
//  ja.add(jo.clone());
//  jo.clear();
 }
  return "";
}

}

         3.數(shù)據(jù)訪問層Bean作為屬性注入業(yè)務(wù)邏輯層實(shí)現(xiàn)類的Property中. (注:不要用NEW創(chuàng)建數(shù)據(jù)訪問層對象,否則得不到ServletContext而報(bào)錯(cuò).)
例:
/**數(shù)據(jù)訪問層Bean（Hibernate自動(dòng)反轉(zhuǎn)工具自動(dòng)配置）*/
 <bean id="userDao" class="com.data.dao.impl.UserDaoImpl">
  <property name="sessionFactory">
   <ref local="sessionFactory" />
  </property>
 </bean>

 /**業(yè)務(wù)邏輯層Bean（Spring配置文檔中手動(dòng)配置，但需先定義好相關(guān)類）*/
 <bean id="userService" class="com.model.service.impl.UserServiceImpl">
  <property name="userDao">
   <ref bean="userDao" />
  </property>
 </bean>

   (三).表示層開發(fā)

       (1)在 faces-config.xml 中配置托管BEAN.(實(shí)現(xiàn)控制層層設(shè)計(jì))
           業(yè)務(wù)層bean作為屬性注入CONTROL層中.

package com.web;
import com.service.ICheckService;

public class SearchAll {
 private ICheckService searchService;
 private String searchData;

 public SearchAll() {
 }

 public ICheckService getSearchService() {
  return searchService;
 }

 public void setSearchService(ICheckService searchService) {
  this.searchService = searchService;
 }

 public String getSearchData() {
  searchData = searchService.searchCheck();
  return searchData;
 }

 public void setSearchData(String searchData) {
  this.searchData = searchData;
 }
}

 <managed-bean>
    <managed-bean-name>userBean</managed-bean-name>
    <managed-bean-class>com.web.SearchAll</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
       <property-name>searchService</property-name>
          <value> #{userService}</value>    //直接引用spring定義的bean
    </managed-property>
    <managed-property>
       <property-name>searchData</property-name>    //頁面中 userBean.name訪問屬性的數(shù)據(jù)
          <value>123</value>                                      //屬性默認(rèn)值
    </managed-property>
 </managed-bean>

        (2)Bean訪問客戶端傳來的參數(shù)值
            HttpServletRequest request=(HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
            String s=request.getParameter("webnam");

七.頁面設(shè)計(jì).(實(shí)現(xiàn)VIEW層設(shè)計(jì)) 

index.faces：(共二行)
<%@ page language="java" pageEncoding="UTF-8"%>     //解決EXTJS 接收數(shù)據(jù)中有中文出現(xiàn)"?????"等亂碼
 ${searchAll.searchData}                                                    //解決JS接收數(shù)據(jù).Ext.store({url：index.faces，...})

    頁面中訪問Bean的二種方法
    方法一：直接在.faces頁面中使用${userBean.property} (推薦)  //property:get/set methord
         注,不能使用${userBean.method}

    <f:view>        //JSF標(biāo)簽必須放在里面
            名稱1: ${userBean.searchData}                              //正確
                   //#{userBean.searchData}                           //報(bào)錯(cuò)
            名稱2: <h:inputText value="#{userBean.searchData}"/>      //正確
                    //<h:inputText value="${userBean.searchData}"/>      //報(bào)錯(cuò)
                    //<input value="#{userBean.searchData}"/>               //報(bào)錯(cuò)
             名稱3: <input value="${userBean.searchData}"/>               //正確,而且仍然可以使用JSF的ManagedBean
    </f:view>
JSF表達(dá)式#{...}只能用在JSF標(biāo)簽里，JSP表達(dá)式${...}也只能用JSP頁面里.
JSP EL的語法格式:${...} 不能放在<%...%>中. 

     方法二： 在.JSP頁面中,直接獲取業(yè)務(wù)層定義的BEAN
<%@ page import="javax.servlet.ServletContext" %>
<%@ page import="org.springframework.context.ApplicationContext" %>
<%@ page import="org.springframework.web.context.support.WebApplicationContextUtils" %>

<%
//獲取ApplicationContext對象
ServletContext   servletContext   =   request.getSession().getServletContext();          
ApplicationContext   ac   =   WebApplicationContextUtils.getWebApplicationContext(servletContext);

//獲取ApplicationContext.xml文件中定義的BEAN
userServiceps=(userService)ac.getBean("userService");

八.導(dǎo)出war
