**Client端**

![这里写图片描述][SouthEast]

**UserController**

@RestController
    @RequestMapping("userClient")
    public class UserController { 
    
        @Autowired
        private UserClient userClient;
    
        @RequestMapping(value = "getUser/{userId}", method = RequestMethod.GET)
        public User getUser(@PathVariable("userId") String userId){
            return userClient.getUser(userId);
        }
    
        @RequestMapping(value = "saveUser", method = RequestMethod.POST)
        public String saveUser(User user){
    
            return userClient.saveUser(user);
        }
    
        @RequestMapping(value = "deleteUser/{userId}", method = RequestMethod.GET)
        public Boolean deleteUser(@PathVariable("userId") String userId){
    
            return userClient.deleteUser(userId);
        }
    
        @RequestMapping(value = "findUserByUserNameAndPassword")
        public User findUserByUserNameAndPassword(String userName, String password){
    
            System.out.println("userClient--->" + userName + " password--->" + password);
    
            return userClient.findUserByUserNameAndPassword(userName, password);
        }
    
    }

**User**

public class User implements Serializable { 
    
        /** serialVersionUID. */
        private static final long serialVersionUID = 1L;
    
        /** id 主键. */
        private String id;
    
        /** 用户名. */
        private String userName;
    
        /** 密码. */
        private String password;
    
        /** 用户类型. */
        private Integer userType;
    
        /** 注册时间. */
        private Date registerTime;
    
        /** 是否有效 0 有效 1 无效. */
        private String validity;
    
        /** 创建时间. */
        private Date createDate;
    
        /** 更新时间. */
        private Date updateDate;
    
        /** 删除标记. */
        private String delFlag;

**UserClient**

@FeignClient("springcloud-userservcie")
    public interface UserClient {
    
        @RequestMapping(value = "userService/getUser/{userId}", method = RequestMethod.GET)
        public User getUser(@PathVariable("userId") String userId);
    
        @RequestMapping(value = "userService/saveUser", method = RequestMethod.POST)
        public String saveUser(User user);
    
        @RequestMapping(value = "userService/deleteUser/{userId}", method = RequestMethod.GET)
        public Boolean deleteUser(@PathVariable("userId") String userId);
    
        @RequestMapping(value = "userService/findUserByUserNameAndPassword", method = RequestMethod.GET)
        public User findUserByUserNameAndPassword(@RequestParam("userName") String userName, @RequestParam("password") String password);    
    
    }

**Service端**

**UserServiceController**

@RestController
    @RequestMapping("userService")
    public class UserServiceController {
    
        @GetMapping("getUser/{userId}")
        public User getUser(@PathVariable("userId") String userId){
    
            System.out.println("获取User,更具UserId，查询User-->" + userId);
    
            User user = new User();
            user.setUserName("Tom");
            user.setPassword("123");
            user.setUserType(1);
            user.setRegisterTime(new Date());
            user.setValidity("0");
    
            return user;
    
        }
    
        @PostMapping("saveUser")
        public String saveUser(@RequestBody User user){
    
            System.out.println("保存User--->" + JSON.toJSONString(user));
    
            return "userId:010100100101";
        }
    
        @GetMapping("deleteUser/{userId}")
        public Boolean deleteUser(@PathVariable("userId") String userId){
    
            System.out.println("删除用户--->" + userId);
    
            return true;
        }
    
        @RequestMapping(value = "findUserByUserNameAndPassword")
        public User findUserByUserNameAndPassword(String userName, String password){
    
            System.out.println("userService--->" + userName + " password--->" + password);
    
            User user = new User();
            user.setUserName("Tomcat");
            user.setPassword("123");
            user.setUserType(1);
            user.setRegisterTime(new Date());
            user.setValidity("0");
    
            return user;
        }
