1. 화면 확인

2. BoardNativeRepository findById 추가

public Board findById(int id) {
        Query query = em.createNativeQuery("select * from board_tb where id = ?", Board.class);
        query.setParameter(1, id);
        return (Board) query.getSingleResult();
    }

3. 테스트 해보기

@Test
public void findById_test(){
    // given
    int id = 1;

    // when
    Board board = boardNativeRepository.findById(id);
    //System.out.println("findById_test "+board);

    // then
    assertThat(board.getTitle()).isEqualTo("제목1");
    assertThat(board.getContent()).isEqualTo("내용1");
}

import static을 해놓으면 앞에 Assert타입 이거 안 적어도 됨! 

BoardController

@GetMapping("/board/{id}")
    public String detail(@PathVariable Integer id, HttpServletRequest request) {
        Board board = boardNativeRepository.findById(id);
        request.setAttribute("board", board);

        return "board/detail";
    }

이거 해줘라! name = id !

@GetMapping("/board/{id}")
    public String detail(@PathVariable (name = "id") int id, HttpServletRequest request) {
        Board board = boardNativeRepository.findById(id);
        request.setAttribute("board", board);

        return "board/detail";
    }
