struts2與spring3整合

最近學習到spring，需要整合struts2，以下是自己的一點心得體會；

首先，引入struts2和spring的核心包，除此以外，還要將struts2-spring-plugin-2.3.14.3.jar和spring web的包都引進來，log4j哪個版本高用哪個；

然後配置web.xml

<?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">
  <display-name></display-name>	
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <!-- 配置struts2 -->
  <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>*.action</url-pattern>
  </filter-mapping>
  
  <!-- 配置spring監視器 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
  </context-param>
  <!-- 開始監聽 -->
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
</web-app>

接着是配置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: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-3.0.xsd
                     http://www.springframework.org/schema/context
                     http://www.springframework.org/schema/context/spring-context-3.0.xsd
                     http://www.springframework.org/schema/aop
                     http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
                     http://www.springframework.org/schema/tx
                     http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
                 
	<bean id="userDao" class="com.liudw.ssh.dao.UserDaoImpl"/>
	
	<bean id="userManager" class="com.liudw.ssh.service.UserManagerImpl">
		<property name="userDao" ref="userDao"/>
	</bean>
	
	<bean id="userAction" class="com.liudw.ssh.action.UserAction">
		<property name="userManager" ref="userManager"/>
	</bean>
</beans>

接着是配置struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
	
	<constant name="struts.objectFactory" value="spring"/>

	<package name="user" namespace="/" extends="struts-default">
		<action name="adduser" class="userAction" method="add">
			<result>/login_success.jsp</result>
		</action>
	</package>
</struts>    

注意"userAction"，此兩處必須完全一致；

主要問題還是引包的問題。
