Connect to second database in Liferay(�q�接�W�二个数据库)

Thu, 27 Oct 2011 09:56:00 GMT

同时�q�接两个数据库，�q�接多个数据�?/font>

�q�是我自��q��I�出来的�Q�真的可以说是世界首发了�Q�网上也有一些例子，都要么就是老版本，要么��q��复杂。我的这个方法特��单，希望对大家有用，也希望大家珍�?/font>

因�ؓ(f��)公司的需要，直接写的英文版的�Q�不惛_��译回来了。都不难理解�Q�一看就能明白。不懂的��L(f��ng)��a�

Introduction

First of all, I should say that setting liferay to connect to another database is very easy. Certainty, all of things to make easy always after numerous attempts . I searched several solutions from website before. But, not only for old version but also too complex. As my understand According to original source, and several trial. I found the way. And I think that it is the World Premiere.^_^

Prerequisites

You should know how to create services with Service Builder, Also You should know how to create new portlet. how to link to database and how it is used inside programming language code.

The steps described here were performed over Liferay 6.0.6.

Let us Beginning

1. Create a file named portal-ext.properties in {WEBSERVER-HOME}\webapps\ROOT\WEB-INF\classes. And type the following code:

    #
    # MySQL
    #
    jdbc.default.driverClassName=com.mysql.jdbc.Driver
    jdbc.default.url=jdbc:mysql://localhost/lfportal?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
    jdbc.default.username=root
    jdbc.default.password=root

    #
    # This is the second connection
    #
    jdbc.second.driverClassName=net.sourceforge.jtds.jdbc.Driver
    jdbc.second.url=jdbc:jtds:sqlserver://localhost:1433/extraDB
    jdbc.second.username=sa
    jdbc.second.password=test

2. Create a service.xml file. And type the following code:

xml version="1.0" encoding="UTF-8"?>
DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.0.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_0_0.dtd">
<service-builder package-path="com.test">
    <author>noah.xiangauthor>
    <namespace>nxnamespace>

    <entity name="MyTable" local-service="true" remote-service="false" table="myTable" data-source="secondDataSource" session-factory="secondSessionFactory" tx-manager="secondTransactionManager">


        <column name="id" type="int" primary="true" />



        <column name="jahr" type="Date" mapping-key="[Jahr]"/>
        <column name="beschaffungsstrategie" type="String"  mapping-key="[Beschaffungsstrategie]"/>
        <column name="buchVon" type="String" mapping-key="[Buch von]"/>

    entity>
service-builder>

3. Ant build-service.xml, let liferay to generate code.

4. Create a new file named ext-spring.xml in src\META-INF folder. And copy the following code:

xml version="1.0"?>
DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
    <bean id="secondDataSource" class="org.springframework.jdbc.datasource.LazyConnectionDataSourceProxy" lazy-init="true">
        <property name="targetDataSource">
            <bean class="com.liferay.portal.dao.jdbc.util.DataSourceFactoryBean">
                <property name="propertyPrefix" value="jdbc.second." />
            bean>
        property>
    bean>
    <bean id="secondHibernateSessionFactory" class="com.liferay.portal.spring.hibernate.PortalHibernateConfiguration" lazy-init="true">
        <property name="dataSource">
            <ref bean="secondDataSource" />
        property>
        <property name="mappingResources">
            <list>
                <value>META-INF/portlet-hbm.xmlvalue>
            list>
        property>
    bean>
    <bean id="secondSessionFactory" class="com.liferay.portal.dao.orm.hibernate.SessionFactoryImpl" lazy-init="true">
        <property name="sessionFactoryImplementor">
            <ref bean="secondHibernateSessionFactory" />
        property>
    bean>
    <bean id="secondTransactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" lazy-init="true">
        <property name="dataSource">
            <ref bean="secondDataSource" />
        property>
        <property name="sessionFactory">
            <ref bean="secondHibernateSessionFactory" />
        property>
    bean>
beans>

5. No more. So easy right? About how to call and deploy it. I believe that you can do.

登陆名如果用中文的话�Q�会(x��)出现��q��Q�导致无法验证通过。解决中文问题无非就是编码问题，其中需要�{换编码的有以下几个地方．

�W�一�Q�在Web.xml文�g里加上Filter�Q�对所有页面进行一�ơ编码�{换．

�W�二步，修改CAS登陆验证��面的编码，如果你没换过�q�个主题的话�Q�默认的是修改WEB-INF\view\jsp\default\ui\casLoginView.jsp文�g�Q�在最上面加上<%@ page pageEncoding="gb2312"%>。这里要特别注意一下，�q�个��面的编码要和上面XML文�g里写的编码一致�?/p>

�W�三步，修改验证成功后做跌��{的页面。也��是WEB-INF\view\jsp\protocol\2.0\casServiceValidationSuccess.jsp文�g�Q�在最上面加上<%@ page pageEncoding="UTF-8"%>。这里特别注意的是这个页面的�~�码要和你蟩转过�ȝ��那个��面的编码一��_(d��)��换句话说�Q�客��L(f��ng)��的验证页面的�~�码要和�q�个地方的一��_(d��)��不一致的话，要�{换一下�?/p>

默认情况下，Liferay中自带的那个搜烦条，��是在右上角的那个，只能搜烦JournalContent的内宏V��其实，我们最��x��索的是JournalArticle中的内容。所以可以把�q�个功能改进一下。修�Ҏ(gu��)��法很��单�?/p>

打开源代码文件util-taglib/src/com/liferay/taglib/util/VelocityTaglib.java
扑ֈ�journalContentSearch()�Ҏ(gu��)��Q�再后面增加一个方法：(x��)
public String journalArticleSearch() throws Exception {
_res.recycle();

SearchTag.doTag(_ctx, _req, _res);

return _res.getString();
}
重新成生util-taglib.Jar包。发布到服务器�?/p>

然后�Q�修改主题包中原来的$theme.journalContentSearch()�?theme.journalArticleSearch()�Q�即可�?/p>

Liferay中��用CAS实现单点登陆(SSO)

Sun, 22 Feb 2009 04:53:00 GMT

单点登陆(SSO)的实现方式有很多�U�，�q�里所说的是用CAS实现�Q�这也是Liferay中所采纳的方式。至于什么是CAS�Q�单点登陆实现的原理�{�，�q�里不做解释�Q�直接一步一步明说实现方式，好了�Q�多一个字的费话也不说了�?/p>

�W�一步，创徏证书

keytool -genkey -alias tomcat -keystore c:\mykeystore -dname "CN=xyb, OU=localhost, O=localhost, L=SH, ST=SH, C=CN" -keypass 123456 -storepass 123456

PS:

-genkey         创徏一个证�?br /> -alias          证书的别�?br /> -keystore       指定生成此证书的路径(可不写，默认存在�pȝ��的Home目录�?keystore文�g�?br /> -storepass      指定密钥库的密码
-keypass        指定别名条目的密�?br /> -dname          指定证书拥有者信�?可不写，但，�pȝ��?x��)提�C�Z��依次输入�q�些信息�Q�特别要注意“CN”的值是你想做�ؓ(f��)CAS服务器的�q�台机器的域名或机器名，但就是不能是IP)
-keyalg         指定密钥的算�?可不�?
-validity       指定创徏的证书有效期多少�?可不写，默认�?0�?

�W�二步，导出证书

keytool -export -alias tomcat -keystore c:\mykeystore -file c:\mycerts.cer -storepass 123456

PS:

-export ��别名指定的证书导出到文�?br /> -keystore 指定生成此证书的路径(上一步中写的什么这��写什么，如果没写�Q�这也不�?
-file 指定导出到文件的文�g�?/p>

�W�三步，把导出的证书导入到客��L(f��ng)��服务�?/p>

keytool -import -trustcacerts -alias tomcat -keystore "%JAVA_HOME%/JRE/LIB/SECURITY/CACERTS" -storepass 123456 -file c:\mycerts.cer

PS:

-import ��已�{�֐�数字证书导入密钥�?br /> -file 指定要导入到密钥库的文�g�?也就是上一步导出的那个文�g)
有一个提�C�：(x��)是否信�Q�q�个证书�Q�输�?Y�Q�回车�?/p>

�W�四步，下蝲cas集成包。将下蝲后的文�g改名为cas-web�Q�放�|�在liferay的webapps目录下，在conf/server.xml中找��C��面这�D�，��L��原有的注释�ƈ修改为：(x��)

�W�五步，在Liferay的webapps\ROOT\WEB-INF\classes\portal-ext.properties下添加如下内容：(x��)

cas.auth.enabled=true
cas.login.url=https://xyb:8443/cas-web/login
cas.logout.url=https://xyb:8443/cas-web/logout
cas.server.name=客户端IP:8080
cas.service.url=
#cas.service.url=http://localhost:8080/c/portal/login
cas.validate.url=https://xyb:8443/cas-web/proxyValidate

如果没在Liferay下，只是普通的Web�E�序可用Filter来实玎ͼ�打开Web-INF\Web.XML文�g�Q�增加如下代�?/p>

<filter>
        <filter-name>CASFilterfilter-name>
        <filter-class>edu.yale.its.tp.cas.client.filter.CASFilterfilter-class>
        <init-param>
            <param-name>edu.yale.its.tp.cas.client.filter.loginUrlparam-name>
            <param-value>https://xyb:8443/cas-web/loginparam-value>
        init-param>
        <init-param>
            <param-name>edu.yale.its.tp.cas.client.filter.validateUrlparam-name>
            <param-value>https://xyb:8443/cas-web/proxyValidateparam-value>
        init-param>
        <init-param>
          <param-name>edu.yale.its.tp.cas.client.filter.serverNameparam-name>
          <param-value>localhost:8080param-value>
        init-param>
    filter>

    <filter-mapping>
        <filter-name>CASFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

最后一步，在客��L(f��ng)��获取CAS认证通过的用户名�Q��ƈ修改�w�䆾验证�E�序为只通过用户名来验证。如是在Liferay下就不用做这一步了�Q�Liferay中本�w�的验证是ScreenName字段

1、在JSP或Servlet中的用法�Q?/p>

<%@ page import="edu.yale.its.tp.cas.client.filter.CASFilter" %>
<%@ page import="javax.servlet.http.HttpServletRequest" %>
<%@ page import="javax.servlet.http.HttpSession" %>
<%
HttpSession ses = request.getSession();

String screenName =
(String)ses.getAttribute(CASFilter.CAS_FILTER_USER);
System.out.println("screenName==:"+screenName);
%>

2、在Java中通过 Session 获取��d��用户�?/p>

// 以下两者都可以
session.getAttribute(CASFilter.CAS_FILTER_USER);
session.getAttribute("edu.yale.its.tp.cas.client.filter.user");

3、在 JSTL 中获取用户名的方�?/p>

<c:out value="${sessionScope[CAS:'edu.yale.its.tp.cas.client.filter.user']}"/>

问题汇总：(x��)

严重: edu.yale.its.tp.cas.client.CASAuthenticationException: Unable to validate ProxyTicketValidator [[edu.yale.its.tp.cas.client.ProxyTicketValidator prox
yList=[null] [edu.yale.its.tp.cas.client.ServiceTicketValidator casValidateUrl=[https://192.168.1.111:8443/cas/proxyValidate] ticket=[ST-0-9h7Mx5HK3pfsdxRv
MD3y] service=[http%3A%2F%2F192.168.1.222%3A8080%2Fservlets-examples%2Fservlet%2FHelloWorldExample] renew=false]]]

�q�个CAS异常是从CAS Client里面抛出�Q�是当我们不使用证书的CN去访问域名的时候（比如上文是用IP讉K��而且证书的CN是该IP对应的域名而非该IP�Q�，CASClient无法信�Q�Q�也��是我上面特意提到的那个CN的问题。要特别注意�?/p>

�q�有一�U�情况就是客��L(f��ng)��证书没有导入,同样也报�q�个错误,最�l�可以归��Z��句话,肯定是证书验证没有通过所�?
