RequestMapping - API

1.  회원 관리 API

---

• 회원 목록 조회: GET /users
• 회원 등록: POST /users
• 회원 조회: GET /users/{userId}
• 회원 수정: PATCH /users/{userId}
• 회원 삭제: DELETE /users/{userId}

 

2. Controller

---

@RestController
public class MappingClassController {

    @GetMapping("/mapping/users/")
    public String user(){
        return "get users";
    }

    @PostMapping("/mapping/users")
    public String addUser(){
        return "post user";
    }

    @GetMapping("/mapping/users/{userId}")
    public String findUser(@PathVariable("userId") String userId){
        return "get userId = " + userId;
    }

    @PatchMapping("/mapping/users/{userId}")
    public String updateUser(@PathVariable("userId") String userId){
        return" update userId = " + userId;
    }    
    
    @DeleteMapping("/mapping/users/{userId}")
    public String deleteUser(@PathVariable("userId") String userId){
        return" update userId = " + userId;
    }
}

• 음 그런데 /mapping/users가 반복된다.
• @RequestMapping에 공통부분은 넣어주면된다.

@RestController
@RequestMapping("/mapping/users")
public class MappingClassController {

    @GetMapping
    public String user(){
        return "get users";
    }

    @PostMapping
    public String addUser(){
        return "post user";
    }

    @GetMapping("/{userId}")
    public String findUser(@PathVariable("userId") String userId){
        return "get userId = " + userId;
    }

    @PatchMapping("/{userId}")
    public String updateUser(@PathVariable("userId") String userId){
        return" update userId = " + userId;
    }

    @DeleteMapping("/{userId}")
    public String deleteUser(@PathVariable("userId") String userId){
        return" update userId = " + userId;
    }
}
