encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                destroy-method="close">                 <property name="driverClassName" value="${driverClassName}" />                 <property name="url" value="${url}" />                 <property

transaction-manager="txManager" />         <!-- 用户DAO实现,实现方式：JDBC      <bean id="userDao" class="cn.tsp2c.sshdemo.dao.impl.UserDaoImpl">         <property name="dataSource" ref="dataSource"/>     </bean>     -->     <!-- 用户DAO实现,实现方式：hibernte  -->         <bean id="userDao" class="cn.tsp2c.sshdemo.dao.impl.hibernate.UserDaoHibernateImpl">         <property name="sessionFactory"

        <property name="userService" ref="userService"/>     </bean> </beans> 其中集成hibernate需要属性文件：jdbc4mysql.properties driverClassName=com.mysql.jdbc.Driver url=jdbc\:mysql\://localhost\:3306/sshdemodb?useUnicode\=true&characterEncoding\=utf-8 username=root password=1234 initialSize=1 maxActive=500 maxIdle=2 minIdle=1 需要配置hibernate的二级缓存，如使用ehcache：在src路径下加入ehcache.xml <?xml version="1.0" encoding="UTF-8"?> <!--       defaultCache 设置节点为缺省的缓存策略      maxElementsInMemory 设置内存中最大允许存在的对象数量      eternal 设置缓存中的对象是否永远不过期      overflowToDisk 把超出内存设定的溢出的对象存放到硬盘上      timeToIdleSeconds 设置缓存对象空闲多长时间就过期,过期的对象会被清除掉      timeToLiveSeconds 设置缓存对象总的存活时间      diskPersistent 当jvm结束时是否把内存中的对象持久化到磁盘      diskExpiryThreadIntervalSeconds 设置用于清除过期对象的监听线程的轮询时间 --> <ehcache>     <diskStore path="e:\cache"/>     <defaultCache  maxElementsInMemory="1000" eternal="false" overflowToDisk="true"         timeToIdleSeconds="120"         timeToLiveSeconds="180"         diskPersistent="false"         diskExpiryThreadIntervalSeconds="60"/>         <cache name="cn.tsp2c.sshdemo.domain.User" maxElementsInMemory="100" eternal="false"     overflowToDisk="true" timeToIdleSeconds="300" timeToLiveSeconds="500" diskPersistent="false"/> </ehcache> 2.2 struts2的配置文件： src/struts.xml <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC     "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"     "<http://struts.apache.org/dtds/struts-2.0.dtd>;"> <struts>     <!-- 指定web应用的默认编码为UTF-8，功能等同于request.setCharacterEncoding() -->     <constant name="struts.i18n.encoding" value="UTF-8"/>     <!-- 指定struts2的请求处理后缀，匹配*.action的所有请求 -->     <constant name="struts.action.extension" value="action"/>     <!-- 关闭struts2的!动态方法调用,建议使用通配符匹配方式实现动态方法调用 -->     <constant name="struts.enable.DynamicMethodInvocation" value="false"/>     <!-- 设置浏览器是否缓存静态页面，默认为true，建议：开发阶段关闭，生产环境打开 -->     <constant name="struts.serve.static.browserCache" value="false" />     <!-- 当struts.xml修改时自动重新加载，默认为false。建议：开发阶段打开，生产环境关闭 -->     <constant name="struts.configuration.xml.reload" value="true"/>     <!-- 开发模式下打开，便于打印详细日志，生产环境下关闭 -->     <constant name="struts.devMode" value="true" />     <!-- 设置视图主题为css_xhtml -->     <constant

        <global-results>                <result name="message">/WEB-INF/page/message.jsp</result>                <result name="error">/WEB-INF/page/error.jsp</result>         </global-results>     </package>          <package name="user" namespace="/user" extends="base">         <action name="login" class="cn.tsp2c.sshdemo.web.action.LoginAction" method="execute">             <result name="success">/index.jsp</result>             <result name="input">/login.jsp</result>         </action>         <action name="user_*" class="cn.tsp2c.sshdemo.web.action.UserAction" method="{1}">             <result name="list">/userlist.jsp</result>             <result name="add" type="redirect">/useradd.jsp</result>         </action>     </package> </struts> 3、需要把spring、strusts2框架注入到web容器（hibernate框架被spring集成，和web容器没有关系。所以不需要在web.xml中配置） web.xml文件： <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee ;         <http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd>;">     <!-- 配置spring的xml文件，若配置文件有多个，可用,或空格分隔 -->         <context-param>                 <param-name>contextConfigLocation</param-name>                 <param-value>                         /WEB-INF/applicationContext.xml                 </param-value>         </context-param>         <!-- web容器加载struts2配置 -->         <filter>                 <filter-name>struts2</filter-name>                 <filter-class>                         org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter                 </filter-class>         </filter>         <filter-mapping>                 <filter-name>struts2</filter-name>                 <url-pattern>/*</url-pattern>         </filter-mapping>         <!-- web容器加载spring配置 -->         <listener>                 <listener-class>                         org.springframework.web.context.ContextLoaderListener                 </listener-class>         </listener>         <!-- web容器增加字符集转换的过滤器,由于struts2框架解决了字符集转码，此配置可以注释掉          <filter>                 <filter-name>encoding</filter-name>                 <filter-class>                         org.springframework.web.filter.CharacterEncodingFilter                 </filter-class>                 <init-param>                         <param-name>encoding</param-name>                         <param-value>UTF-8</param-value>                 </init-param>         </filter>         <filter-mapping>                 <filter-name>encoding</filter-name>                 <url-pattern>/*</url-pattern>         </filter-mapping>     -->         <!-- 解决hibernate的session关闭导致延迟加载异常的问题 -->         <!--                   <filter>                 <filter-name>Spring OpenEntityManagerInViewFilter</filter-name>                 <filter-class>                   org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter

                  <url-pattern>/*</url-pattern>                 </filter-mapping>         -->         <welcome-file-list>                 <welcome-file>index.jsp</welcome-file>         </welcome-file-list> </web-app> 3.1 web容器集成spring         <!-- 配置spring的xml文件，若配置文件有多个，可用,或空格分隔 -->         <context-param>                 <param-name>contextConfigLocation</param-name>                 <param-value>                         /WEB-INF/applicationContext.xml                 </param-value>         </context-param>         <!-- web容器加载spring配置 -->         <listener>                 <listener-class>                         org.springframework.web.context.ContextLoaderListener                 </listener-class>         </listener> 3.2 web容器集成struts2         <!-- web容器加载struts2配置 -->         <filter>                 <filter-name>struts2</filter-name>                 <filter-class>                         org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter                 </filter-class>         </filter>         <filter-mapping>                 <filter-name>struts2</filter-name>                 <url-pattern>/*</url-pattern>         </filter-mapping> 3.3 关于在session范围内解决hibernate的延迟加载问题 <!-- 解决hibernate的session关闭导致延迟加载异常的问题 --> <filter>     <filter-name>HibernateSessionInViewFilter</filter-name>     <filter-class>       org.springframework.orm.hibernate3.support.OpenSessionInViewFilter     </filter-class> </filter> <filter-mapping>     <filter-name>HibernateSessionInViewFilter</filter-name>     <url-pattern>/*</url-pattern> </filter-mapping> 4、如何使用s2sh框架实现MVC 4.1 action struts.xml:     <!-- 指定struts中action交由spring创建 -->     <constant name="struts.objectFactory" value="spring"/> <action name="user_*" class="cn.tsp2c.sshdemo.web.action.UserAction" method="{1}">     <result name="list">/userlist.jsp</result>     <result name="add" type="redirect">/useradd.jsp</result> </action> 在spring中配置： <!-- 用户Action bean,scope=prototype符合struts2的action生成机制 -->     <bean id="userAction" class="cn.tsp2c.sshdemo.web.action.UserAction" scope="prototype">         <property name="userService" ref="userService"/>     </bean> 4.2 service <!-- 用户服务bean --> <bean id="userService" class="cn.tsp2c.sshdemo.service.impl.UserServiceImpl" >    <property name="userDao" ref="userDao"/> </bean> 4.3 dao <!-- 用户DAO实现,实现方式：JDBC --> <bean id="userDao" class="cn.tsp2c.sshdemo.dao.impl.UserDaoImpl">     <property name="dataSource" ref="dataSource"/> </bean>
