1.struts2整合Spring

web.xml

    <!-- 整合配置：struts -->
    <filter>
        <filter-name>strut2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
        <!-- 如果struts.xml在src的根目录下则不用配置,不在就要做如下配置： -->
        <init-param>
            <param-name>config</param-name><!-- config名不能变 -->
            <param-value>struts-default.xml,struts-plugin.xml,config/struts.xml</param-value>
        </init-param>

    </filter-mapping>
    <!-- 整合配置：spring -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 如果applicationContext.xml文件如果在在web_info目录下则不用配置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name><!-- contextConfigLocation名不能改 -->
        <param-value>classpath:config/applicationContext.xml</param-value>
    </context-param>
</web-app>

struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
    "http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
    <package name="qq" extends="struts-default">
        <action name="user" class="userController">
        <result name="list" type="dispatcher">WEB-INF/per/list.jsp</result><!-- 默认为转发 -->
        <result name="add">WEB-INF/per/add.jsp</result>
        <!-- struts中默认为转发即type="dispatcher",重定向为 redirect -->
        <result name="update">WEB-INF/per/update.jsp</result>

        </action>
    </package>
</struts>

applicationContext.xml
<bean id="userController" class="com.hw.dao.impl.StudentDaoImpl"></bean>

2.Spring整合hibernate(完全整合)

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <!-- 分开整 合hibernate, configLocation名不能变,只需要
     <property name="configLocation" value="classpath:config/hibernate.cfg.xml"/>即操作数据库交给
     hibernate -->
    <!-- spring 完全整合hibernate,整个工程 不需要 hibernate.cfg.xml-->
    <property name="dataSource" ref="dataSource"></property>
    <!-- 设置hibernate属性 -->
    <property name="hibernateProperties">
      <props>
      <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
      <prop key="hibernate.hbm2ddl.auto">update</prop>
      <prop key="hibernate.show_sql">true</prop>
      <prop key="hibernate.format_sql">true</prop>
      </props>
    </property>
    <!-- 配置hibernate的映射文件 -->
    <property name="mappingResources">
     <list>
      <value>com/hw/entity/User.hbm.xml</value>
     </list>
     <!-- <property name="mappingDirectoryLocations">
     <list>
     <!-- spring容器会去该包或者子包下搜素所有的映射文件 
      <value>com/hw/entity</value>
     </list>-->
    </property>
    </bean>
    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
      <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

2.Spring整合hibernate(分开整合)

</bean>
    <!-- 分开整 合hibernate -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <!-- configLocation名不能变 -->
     <property name="configLocation" value="classpath:config/hibernate.cfg.xml"/>
    </bean>
    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
      <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

3.事物

<!-- xml方式配置 -->
     <aop:aspectj-autoproxy proxy-target-class="true" /><!-- 激活自动代理功能 -->
    <!-- 定义事务通知 -->
    <tx:advice id="transactionManager" transaction-manager="transactionManager">
      <!-- 定义事务传播规则 -->
      <tx:attributes>
      <tx:method name="add*" propagation="REQUIRED"/>
      <tx:method name="update*" propagation="REQUIRED"/>
      <tx:method name="del*" propagation="REQUIRED"/>
       <tx:method name="*" propagation="REQUIRED" read-only="true"/>
      <!-- 也可以对所有方法都应用REQUIRED事务规则 
      <tx:method name="*" propagation="REQUIRED"/>-->
       </tx:attributes>
     </tx:advice>


    <aop:config> <!-- 定义一个切面，并将事务通知和切面组合 -->
    <aop:pointcut expression="execution(* com.dao.impl.*.*(..))" id="perform"/>
    <aop:advisor advice-ref="transactionManager" pointcut-ref="perform"/>
    </aop:config>
