S2SH框架集成步骤:
1、框架依赖jar文件
(这些jar包可以去官网自己下载,地址不在连接)
1.1 sping 所依赖工程 spring-framework-2.5.6
dist\spring.jar
lib\cglib\cglib-nodep-2.1_3.jar

2、框架的配置文件
2.1 spring框架配置文件及集成hibernate、二级缓存
$WEB_ROOT/WEB-INF/applicationContext.xml
src/ehcache.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<http://www.springframework.org/schema/beans/spring-beans-2.5.xsd>
<http://www.springframework.org/schema/context> <http://www.springframework.org/schema/context/spring-context-2.5.xsd>
<http://www.springframework.org/schema/aop> <http://www.springframework.org/schema/aop/spring-aop-2.5.xsd>
<http://www.springframework.org/schema/tx> <http://www.springframework.org/schema/tx/spring-tx-2.5.xsd>">
<!-- 配置数据源 -->
<context:property-placeholder location="classpath:jdbc4mysql.properties" />
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${driverClassName}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
<!-- 连接池启动时的初始值 -->
<property name="initialSize" value="${initialSize}" />
<!-- 连接池的最大值 -->
<property name="maxActive" value="${maxActive}" />
<!-- 最大空闲值.当经过一个高峰时间后,连接池可以慢慢将已经用不到的连接慢慢释放一部分,一直减少到maxIdle为止 -->
<property name="maxIdle" value="${maxIdle}" />
<!-- 最小空闲值.当空闲的连接数少于阀值时,连接池就会预申请去一些连接,以保证应急 -->
<property name="minIdle" value="${minIdle}" />
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>cn/tsp2c/sshdemo/domain/User.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.hbm2ddl.auto=update
hibernate.show_sql=false
hibernate.format_sql=false
hibernate.cache.use_second_level_cache=true
hibernate.cache.use_query_cache=false
hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider
</value>
</property>
</bean>
<!-- 配置事务管理器 -->
<bean id="txManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- spring支持两种事务声明方式:注解和xml配置,建议使用注解方式 -->
<!-- 采用@Transactional注解方式使用事务,在dao类及方法需用注解方式标明事务方式 -->
<tx:annotation-driven 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" ref="sessionFactory"/>
</bean>
<!-- 用户服务bean -->
<bean id="userService" class="cn.tsp2c.sshdemo.service.impl.UserServiceImpl" >
<property name="userDao" ref="userDao"/>
</bean>
<!-- 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>
</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 name="struts.ui.theme" value="simple" />
<!-- 指定struts中action交由spring创建 -->
<constant name="struts.objectFactory" value="spring"/>
<package name="base" extends="struts-default">
<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
</filter-class>
</filter>
<filter-mapping>
<filter-name>Spring OpenEntityManagerInViewFilter</filter-name>
<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>
