一：添加Struts2+Spring4+Hibernate4所需的jar文件:

1、将下载好的Struts2 jar，Spring4 jar ，Hibernate4 jar 放到MyEclipse-->WEBROOT/WEB-INF/lib下。如图：

添加好Jar后，接下来就是配置文件了。

二：配置Struts2+Spring4+Hibernate4文件:

1、配置web.xml

<?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_3_0.xsd" id="WebApp_ID" version="3.0">
	<display-name>HelloZw</display-name>
	<!-- spring4配置 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/config/spring/*.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 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>
	<filter>
		<filter-name>struts2_1</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts2_1</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>
	
	<!-- hibernate4配置 -->
	<filter>
		<filter-name>hibernateFilter</filter-name>
		<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
		<init-param>
			<param-name>sessionFactoryBeanName</param-name>
			<param-value>mySessionFactory</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>hibernateFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
</web-app>

2、配置struts.xml文件：

<?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>

    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="false" />
    <constant name="struts.custom.i18n.resources" value="globalMessages" />

    <!-- Add packages here -->
	<package name="blog" namespace="/" extends="struts-default">
		<action name="placeOrder">
			<result>/neworder.jsp</result>
		</action>
		
		<action name="saveNewOrder" class="saveNewOrderAction">
			<result name="input">/neworder.jsp</result>
			<result>/vieworder.jsp</result>
		</action>
		
		<action name="findOrder">
			<result>/queryorder.jsp</result>
		</action>
		
		<action name="findOrderID" class="findOrderAction">
			<result name="input">/queryorder.jsp</result>
			<result>/vieworder.jsp</result>
		</action>
	</package>
	
</struts>

3、配置Spring4和Hibernate4(注：我把hibernate放到Spring中管理，所以没有hibernate-cfg.xml)，文件在WEB-INF\config\spring\applicationContext.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: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-3.0.xsd
			http://www.springframework.org/schema/tx 
			http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
			http://www.springframework.org/schema/aop 
			http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
		
	<!-- 配置数据源 -->
	<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName">

		<property name="username">

		</property>
		<property name="password">

		</property>
	</bean>

	<!-- 配置SessionFactory -->
	<bean id="mySessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<property name="mappingResources">
			<list>
				<value>us/zhwe/hellozw/model/Order.hbm.xml</value>
				<value>us/zhwe/hellozw/model/OrderLineItem.hbm.xml</value>
			</list>
		</property>

		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">

			</props>
		</property>

		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
	</bean>

	<!-- 配置TransactionManager -->
	<bean id="myTxManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="mySessionFactory" />
	</bean>
	
	<!-- 配置事务策略 -->
	<tx:advice id="txAdvice" transaction-manager="myTxManager">

			<tx:method name="save*" propagation="REQUIRED" />
			<tx:method name="*" propagation="SUPPORTS" read-only="true" />
		</tx:attributes>
	</tx:advice>
	
	<aop:config>
		<aop:pointcut id="serviceMethods" 
			expression="execution(* us.zhwe.hellozw.service.*.*(..))" />
		<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethods" />
	</aop:config>
	
	<bean id="orderDAO" class="us.zhwe.hellozw.hibernate.OrderHibernateDAO">
		<property name="sessionFactory">
			<ref local="mySessionFactory" />
		</property>
	</bean>

	<bean id="orderService" class="us.zhwe.hellozw.service.spring.OrderServiceSpringImpl">
		<property name="orderDAO">
			<ref local="orderDAO" />
		</property>
	</bean>

	<bean id="saveNewOrderAction" class="us.zhwe.hellozw.action.SaveOrderAction"
		scope="prototype">
		<property name="orderService">
			<ref local="orderService" />
		</property>
	</bean>

	<bean id="findOrderAction" class="us.zhwe.hellozw.action.FindOrderAction"
		scope="prototype">
		<property name="orderService">
			<ref local="orderService" />
		</property>
	</bean>
</beans>

注意：里面有我测试的文件，你们添加的时候要按照自己的需求来添加。
