本文介绍如何将Struts2与Spring框架进行整合，包括必要的Jar文件、web.xml配置、struts.properties设置、Spring配置文件、struts.xml配置及Action类实现。通过这些步骤，可以实现Spring对Struts2组件的管理。

1. Jar 文件整合除了Struts2必须的jar文件:

> struts2-core-xxx.jar

> xwork-xxx.jar

> ognl-xxx.jar

> freemarker-xxxjar

> commons-logging-xxx.jar

以外,还需要Spring的核心jar文件:

spring-core.jar
spring-beans.jar
spring-context.jar
spring-web.jar
struts2-spring-plugin-xxx.jar // Spring与struts2的插件jar

注: xxx 是具体的版本号.对于其他扩展的jar文件,可自行添加

2. web.xml 配置,可参考:

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
   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">

   
   <filter>
       <filter-name>struts_cleanup</filter-name>
       <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
   </filter>
   <filter-mapping>
       <filter-name>struts_cleanup</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>

   
   <filter>
       <filter-name>struts2</filter-name>
       <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
   </filter>
   <filter-mapping>
       <filter-name>struts2</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>

   
   <listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>

   <welcome-file-list>
       <welcome-file>default.jsp</welcome-file>
   </welcome-file-list>
</web-app>

3. struts.properties. 位于类路径下,可自行创建,配置如下:

#spring context
struts.objectFactory = spring

4. applicationContext.xml. Spring配置文件,位于WEB-INF目录,可参考:

<?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:tx="http://www.springframework.org/schema/tx"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
               http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
               http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

   <bean id="lotteryService" class="com.mkk.struts2.service.LotteryServiceImpl" />

   <bean id="springAction" class="com.mkk.struts2.spring.SpringAction"
       scope="prototype">
       <property name="lotteryService" ref="lotteryService" />
   </bean>

</beans>

5. struts.xml. Struts2配置文件,位于类路径下.可参考:

<?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>

<package name="spring_package" extends="struts-default" namespace="/spring">
       <action name="spring" class="springAction">
           <result>/spring/spring.jsp</result>
       </action>
   </package>

</struts>

注意: action的class值是对应的Spring配置文件中bean的id.

6. 对应的Action类.可参考:

public class SpringAction extends ActionSupport implements InitializingBean {

   /**
   * serialVersionUID
   */
   private static final long serialVersionUID = -1506018657717304870L;

   private LotteryService lotteryService;

   public String init() throws Exception {
       getLottery();
       return super.execute();
   }

   /**
   * Lottery action
   *
   * @return
   * @throws Exception
   */
   public String lottery() throws Exception {
       getLottery();
       return SUCCESS;
   }

   private void getLottery() {
       String res = lotteryService.getNextRandomLotteryNumber();
       ServletActionContext.getRequest().setAttribute("result", res);
   }

   public void setLotteryService(LotteryService lotteryService) {
       this.lotteryService = lotteryService;
   }

   public void afterPropertiesSet() throws Exception {
       Assert.notNull(lotteryService);
   }

}
