struts2、spring整合

前文已经搭建好了struts2环境，而在struts2的基础上集成spring，则需要加入spring的核心jar包已经相应的struts-spring插件以及commons-logging.jar

1.首先导入所需jar包

2.在web-inf下添加spring配置文件applicationContext.xml

3.在web.xml中加入spring组件：

<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>

 4.将建好的action交给spring去管理，即在applicationContext.xml添加action的bean配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns ="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-2.0.xsd">
    
    <bean name="helloWorldAction" class="ssmdemo.HelloWorld" />
    	
</beans>
5.最后修改struts.xml文件

 

<!-- 告知Struts 2运行时使用Spring来创建对象 -->
    <constant name="struts.objectFactory" value="spring" />

    <package name="struts2" extends="struts-default">  
        <action name="HelloWorld" class="helloWorldAction">  
            <result>/HelloWorld.jsp</result> 
       </action>  
    </package>
