本文提供Struts2整合Spring Hibernate的CRUD的实例的源代码

1. 数据库脚本，数据库采用MySQL 5.0

CREATE TABLE `user` (
`id` int(11) NOT NULL auto_increment,
`username` varchar(32) NOT NULL,
`password` varchar(32) NOT NULL,
PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

2. 几个重要的文件

web.xml

<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app version=”2.5″ xmlns=”[url=http://java.sun.com/xml/ns/javaee]http://java.sun.com/xml/ns/javaee[/url]”
xmlns:xsi=”[url=http://www.w3.org/2001/XMLSchema-instance]http://www.w3.org/2001/XMLSchema-instance[/url]”
xsi:schemaLocation=”[url=http://java.sun.com/xml/ns/javaee]http://java.sun.com/xml/ns/javaee[/url]
[url=http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd]http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd[/url]“>
<!– spring的应用上下文 –>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext*.xml</param-value>
</context-param>
<!– struts2 过滤器 –>
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!– spring的监听器，以便在启动时就自动加载spring的配置 –>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!– OpenSessionInViewFilter过滤器 –>
<filter>
<filter-name>lazyLoadingFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>lazyLoadingFilter</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>/user/userAdd.jsp</welcome-file>
</welcome-file-list>
</web-app>

applicationContext.xml

struts.xml

<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE struts PUBLIC “-//Apache Software Foundation//DTD Struts Configuration 2.0//EN” “[url=http://struts.apache.org/dtds/struts-2.0.dtd]http://struts.apache.org/dtds/struts-2.0.dtd[/url]“>
<struts>
<include file=”struts-default.xml” />
<!– 此constant设置临时文件存放目录，因为默认的default.properties中没有指定 –>
<constant name=”struts.multipart.saveDir” value=”c:\”></constant>
<!– 将action托管给spring –>
<constant name=”struts.objectFactory” value=”spring”></constant>
<package name=”SSH2″ extends=”struts-default”>
<action name=”userAdd” method=”userAdd”>
<result name=”success” type=”redirect”>userList.action</result>
</action>
<action name=”userList” method=”userList”>
<result name=”success”>/user/userList.jsp</result>
</action>
<action name=”userDelete”
method=”userDelete”>
<result name=”success” type=”redirect”>userList.action</result>
</action>
<action name=”userEdit”
method=”userEdit”>
<result name=”success”>/user/userEdit.jsp</result>
</action>
<action name=”userUpdate”
method=”userUpdate”>
<result name=”success” type=”redirect”>userList.action</result>
</action>
</package>
</struts>

3. 本实例仅实现CRUD功能，没有实现其他的处理，如数据校验、国际化、分页等.
