[ SessionUser 클래스 생성 ]

package shop.mtcoding.blog.user;

import lombok.Data;

import java.sql.Timestamp;

@Data
public class SessionUser {
    private Integer id;
    private String username;
    private String email;
    private Timestamp createdAt;

    public SessionUser(User user) {
        this.id = user.getId();
        this.username = user.getUsername();
        this.email = user.getEmail();
        this.craetedAt = user.getCreatedAt();
    }
}

[ Service ]

public SessionUser 로그인(UserRequest.LoginDTO reqDTO){
        User user = userJPARepository.findByUsernameAndPassword(reqDTO.getUsername(), reqDTO.getPassword())
                .orElseThrow(() -> new Exception401("인증되지 않았습니다"));
        return new SessionUser(user);
    }

[ 컨트롤러 ]

@PostMapping("/login")
    public ResponseEntity<?> login(@RequestBody UserRequest.LoginDTO reqDTO) {
        SessionUser sessionUser = userService.로그인(reqDTO);
        session.setAttribute("sessionUser", sessionUser);
        return ResponseEntity.ok(new ApiUtil(null));
    }

[ 회원 수정도... ]

        User user = userJPARepository.findById(id)
                .orElseThrow(() -> new Exception404("회원정보를 찾을 수 없습니다"));

        user.setPassword(reqDTO.getPassword());
