Spring struts2 hibernate 整合

整合的时候，Spring管理hibernate的sessionfactory，struts2的action。当然action有时候是有状态的，有时候无状态，可在Spring配置里加入scope="singleton"或者scope="prototype"。

 

现在看看如何配置。

配置WEB.XML（添加上struts2的过滤器和Spring的监听器）

<?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"> <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> <!-- 当没有配置多个applicationContext的话，可以不用配置 --><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext-*.xml</param-value></context-param> <listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list></web-app>

 

配置Spring文件applicationContext.xml(IOC管理了Action,Sessionfactory,Bean)，Spring文件已经将hibernate的信息都配置了，所以hibernate.cfg.xml可以为空白的

<?xml version="1.0" encoding="UTF-8"?><beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"><!-- hibernate start --><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"><property name="driverClassName" value="com.mysql.jdbc.Driver" /><property name="url" value="jdbc:mysql://localhost:3306/test" /><property name="username" value="root" /><property name="password" value="sa" /><property name="maxActive" value="100" /><property name="minIdle" value="30" /><property name="maxWait" value="500" /><property name="defaultAutoCommit" value="true" /></bean><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop></props></property><property name="mappingResources"><list><value>com/test/bean/YourBean.hbm.xml</value></list></property></bean><!-- hibernate end --><!-- dao start --><bean id="yourDaoImpl" class="com.test.dao.impl.YourDaoImpl"><property name="sessionFactory" ref="sessionFactory" /></bean><!-- dao end --><!-- service start --><bean id="yourServiceImpl" class="com.test.service.impl.YourServiceImpl"><property name="yourDao" ref="yourDaoImpl" /></bean><!-- service end --><!-- action start --><bean id="yourAction" class="com.test.action.YourAction" scope="prototype"><property name="yourService" ref="yourServiceImpl" /></bean><!-- action end --></beans>

 

配置struts2文件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><package name="default" extends="struts-default"><action name="regist" class="yourAction"><result name="success" type="redirect">/main.jsp</result><result name="input">/regist.jsp</result></action></package></struts>
