struts2项目引入SpringMVC

1、导入jar包

Spring-beans-XXXX.RELEASE.jar (xxxx为版本号)
Spring-aop-XXXX.RELEASE.jar
Spring-context-XXXX.RELEASE.jar
Spring-core-XXXX.RELEASE.jar
Spring-expression-XXXX.RELEASE.jar
Spring-web-XXX.RELEASE.jar
Spring-webmvc-XXXX.RELEASE.jar
还有这个必须的 jar包 ----- commons-logging-XXXX.jar（原项目中有就没导入）

2、修改web.xml，将struts2的拦截从/*改为拦截.do和.action并加入springmvc配置

<filter-mapping>
        <filter-name>Struts2</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping> 
    <filter-mapping>
        <filter-name>Struts2</filter-name>
        <url-pattern>*.action</url-pattern>
</filter-mapping>
 
<!-- SpringMVC配置 -->  
   <servlet>  
       <servlet-name>springmvc</servlet-name>  
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
       <init-param>  
           <param-name>contextConfigLocation</param-name>  
           <param-value>classpath:spring-mvc.xml</param-value>  
       </init-param>  
       <load-on-startup>1</load-on-startup>  
   </servlet>  
   <servlet-mapping>  
       <servlet-name>springmvc</servlet-name>  
       <url-pattern>*.mvc</url-pattern>  
   </servlet-mapping>  
<!-- End SpringMVC配置 --> 

3、在src/main/resources中创建spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"
       default-autowire="byName">
 
    <!-- 视图解析器 -->
 
    <!-- 定义支持注解的HanlderMapping,用于分发请求 -->
    <mvc:annotation-driven/>
 
    <!-- 设置使用注解的类所在的jar包 -->
    <context:component-scan base-package="com.ssit.whfcs.af.action.controller"/>
</beans>

4、创建controller测试

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
 
@Controller
public class HelloController {
   @ResponseBody
   @RequestMapping(value="/sayHello")
   public String sayHello(){
      System.out.println("hello");
      return "hello";
   }
   @ResponseBody
   @RequestMapping(value="/sayMessage")
   public Message sayMessage(){
      Message msg = new Message();
      System.out.println("Message");
      return msg;
   }
}

4、访问

http://localhost:8090/whfcs/sayHello.mvc
返回

hello
