spring3 struts2 hibernate3整合

此种整合思路是尽量把需要配置的东西整合进applicationContext.xml中

步骤：
1、创建工程，设置编码utf-8，jsp编码
2、导入jar包
3、工程下创建三个source文件夹：
src（已存在）
config 配置文件所在
test 测试类所在
4、src下创建持久化类+映射文件
5、在config中创建spring文件夹，写spring的配置文件，引入sessionFactory

<!-- 1.引入dbcp配置文件 -->    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations">            <value>classpath:jdbc.properties</value>        </property>    </bean>    <!-- 2.配置数据源参数 -->    <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">        <property name="driverClassName" value="${jdbc.driverClassName}" />        <property name="url" value="${jdbc.url}" />        <property name="username" value="${jdbc.username}" />        <property name="password" value="${jdbc.password}" />    </bean><!-- 3.1 第二种sessionFactory配置方法 -->    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">        <property name="dataSource" ref="dataSource"></property>        <!-- 指向了映射文件所在的路径 -->        <property name="mappingDirectoryLocations">            <list>                <!-- spring容器会去该包及子包下搜索所有的映射文件 -->                <value>classpath:com/itheima11/s2sh/domain</value>            </list>        </property>        <property name="hibernateProperties">            <props>                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>                <prop key="hibernate.show_sql">true</prop>                <prop key="hibernate.hbm2ddl.auto">update</prop>            </props>        </property>    </bean>

6、测试是否能建表
（只要new ClassPathXMLApplicationContext(“spring/applicationContext.xml”)即可了）

@Test    public void test() {        ApplicationContext context = new ClassPathXmlApplicationContext("spring/applicationContext.xml");    }

7、创建dao，service层，并且在spring容器中配置，注意dao的实现类继承了HibernateDaoSupport，配置上有sessionFactory注入
8、在spring中声明事物处理配置：
事物管理器声明、事务策略、aop:advisor

    <!-- 事务管理器 -->    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">        <property name="sessionFactory">            <ref bean="sessionFactory" />        </property>    </bean>    <!-- 声明事物策略 -->    <tx:advice id="tx" transaction-manager="transactionManager">        <tx:attributes>            <!-- 什么样方法采取什么策略 -->            <tx:method name="save*" read-only="false" />        </tx:attributes>    </tx:advice>    <aop:config>        <aop:pointcut expression="execution(* com.itheima11.s2sh.service.impl.*.*(..))"            id="point1" />        <aop:advisor advice-ref="tx" pointcut-ref="point1" />    </aop:config>

9、写动作类
10、在spring中配置动作类，注意多例 scope=”prototype”
11、测试Action类

@Test    public void testAction() {        ApplicationContext context = new ClassPathXmlApplicationContext("spring/applicationContext.xml");        context.getBean("personAction");    }

12、在config根目录：写struts配置文件

<?xml version="1.0" encoding="UTF-8" ?>    <!DOCTYPE struts PUBLIC        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"        "http://struts.apache.org/dtds/struts-2.3.dtd">    <struts>        <!-- 简单样式 -->        <constant name="struts.ui.theme" value="simple"></constant>        <constant name="struts.devMode" value="true"/>        <include file="struts/struts-person.xml"></include>    </struts>

13、写上述包含的strut-person.xml

<?xml version="1.0" encoding="UTF-8" ?>    <!DOCTYPE struts PUBLIC          "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"            "http://struts.apache.org/dtds/struts-2.3.dtd">    <struts>        <package name="person" namespace="/" extends="struts-default">            <action name="personAction_*" method="{1}" class="personAction">                  </action>        </package>    </struts>

14、写web.xml文件

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">  <display-name>s2sh_integration</display-name>  <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>  <!-- struts2过滤器 -->    <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>    <!-- spring容器和配置文件路径 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring/applicationContext.xml</param-value>    </context-param></web-app>

15、启动项目，测试即可
