项目原本是springmvc项目，新增了resuful接口服务端。

IUserService.java

package com.yq.publicproject.server;import javax.ws.rs.core.MediaType;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import com.yq.publicproject.model.User;/** * spring MVC风格的restful接口  * @author Administrator * */@RequestMapping("/userService")  @Controller public interface IUserService {	@RequestMapping(value = "/hello", produces = "text/plain;charset=UTF-8")      public @ResponseBody      String hello();              @RequestMapping(value = "/say/{msg}", produces = "application/json;charset=UTF-8")      public @ResponseBody      String say(@PathVariable(value = "msg") String msg);              @RequestMapping(value = "/user/{id:\\d+}", method = RequestMethod.GET, produces = "application/json;charset=UTF-8")      public @ResponseBody      String getUser(@PathVariable("id") int id);                  @RequestMapping(value = "/user/{id:\\d+}", method = RequestMethod.DELETE)      public @ResponseBody Object deleteUser(@PathVariable("id") int id) ;            /**      * 推荐使用，这种可以解决绝大多数问题      * @param person      * @return      */      @RequestMapping(value = "/user", method = RequestMethod.POST,               produces = {MediaType.APPLICATION_JSON,"application/json;charset=UTF-8"},              consumes = {MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})      public String addUser(User user);                  @RequestMapping(value = "/user", method = RequestMethod.PUT)      public @ResponseBody Object updateUser(@RequestBody User user);}

UserService.java

package com.yq.publicproject.server.impl;import org.apache.log4j.Logger;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.ResponseBody;import com.alibaba.fastjson.JSONObject;import com.yq.publicproject.model.User;import com.yq.publicproject.server.IUserService;/** * spring MVC风格的restful接口  * @author Administrator * */@Controllerpublic class UserService implements IUserService {		/** 日志实例 */      private static final Logger logger = Logger.getLogger(UserService.class);      public @ResponseBody      String hello() {          logger.info("hello........");          return "你好！hello";      }        public @ResponseBody      String say(@PathVariable(value = "msg") String msg) {          return "{\"msg\":\"you say:'" + msg + "'\"}";      }        public @ResponseBody      String getUser(@PathVariable("id") int id) {          logger.info("获取人员信息id=" + id);          User user = new User();          user.setUserName("张三");          user.setUserId(id+"");                    String jsonObject = JSONObject.toJSONString(user);          logger.info(jsonObject);          return jsonObject;      }            public Object deleteUser(@PathVariable("id") int id) {          logger.info("删除人员信息id=" + id);          JSONObject jsonObject = new JSONObject();              jsonObject.put("msg", "删除人员信息成功");      return jsonObject;      }          public @ResponseBody String addUser(@RequestBody User user) {          logger.info("注册人员信息成功id=" + user.getUserId());          JSONObject jsonObject = new JSONObject();          jsonObject.put("msg", "注册人员信息成功");          return jsonObject.toString();      }            public @ResponseBody Object updateUser(@RequestBody User user) {          logger.info("更新人员信息id=" + user.getUserId());          JSONObject jsonObject = new JSONObject();          jsonObject.put("msg", "更新人员信息成功");          return jsonObject.toString();      }}

因为web.xml进行了如下配置，所有访问url都加上.htmls

    		
     
      spring mvc servlet
     		
     
      rest
     		
     
      org.springframework.web.servlet.DispatcherServlet
     		
     			
      
       contextConfigLocation
      			
      
       				classpath:config/spring-mvc.xml			
      		
     		
     
      1
     	
    	
    		
     
      rest
     		
     
      *.htmls
     	
    

启动Tomcat服务，输入接口访问url。

1.http://localhost:8080/public_project/userService/hello.htmls

2.http://localhost:8080/public_project/userService/say/%E4%BD%A0%E8%BF%99%E4%B8%AA%E7%AC%A8%E8%9B%8B.htmls

3.http://localhost:8080/public_project/userService/user/1.htmls

id 为 1 有数据。
