sprngmvc+restFul 请求报错：404

服务端代码

control类

     @RequestMapping(value="getUser",method = RequestMethod.POST)
     @ResponseBody
     public User getUser(HttpServletRequest request){
         String name = request.getParameter("name");
         String age = request.getParameter("age");
         User user = new User();
         user.setPassWord("123123");
         user.setUserName("asdasd");
         return user;
     }

spring核心控制器

     <!--配置Springmvc核心控制器 -->
     <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:springMVC.xml</param-value>
         </init-param>
     </servlet>
     <servlet-mapping>
         <servlet-name>springmvc</servlet-name>
         <url-pattern>*.action</url-pattern>
     </servlet-mapping>

客户端代码

         JSONObject json = new JSONObject();
         DefaultHttpClient httpClient = new DefaultHttpClient();
         HttpPost method = new HttpPost(url);
         // 接收参数json列表
         JSONObject jsonParam = new JSONObject();

         StringEntity entity = new StringEntity(jsonParam.toString(), "utf-8");//解决中文乱码问题
         entity.setContentEncoding("UTF-8");
         entity.setContentType("application/json");
         method.setEntity(entity);

         HttpResponse result = httpClient.execute(method);
         // 请求结束，返回结果
         String resData = EntityUtils.toString(result.getEntity());
         JSONObject resJson = json.parseObject(resData);
         System.out.printf(":::"+resJson.toString());
     }
 }

调用报错：http.404

报错原因：服务端配置的核心控制器，只拦截以 “.action”结尾的请求

解决方案：将服务端核心控制器配置“<url-pattern>*.action</url-pattern>”改为“<url-pattern>/</url-pattern>”
