[스프링 부트] 14. 글 삭제(Delete) 구현

1. 삭제 버튼 생성

<form action="/board/{{model.id}}/delete" method="post">
				<!-- body는 필요x, id는 패스변수에 있다 -->
        <button type="submit">삭제</button>
    </form>

2. Repository

public void delete(int id) {
        Query q = em.createNativeQuery("delete from board_tb where id=?");
        q.setParameter(1, id);
        q.executeUpdate(); // insert, update, delete 때 사용
    }

3. Repository Test

@Test
    public void delete_test() {
        // given
        int id = 1;
        // when
        boardRepository.delete(id);
        // then
        List<Board> boardList = boardRepository.findAll();
        System.out.println("size : " + boardList.size());
    }

4. Controller

@PostMapping("/board/{id}/delete")
    public String delete(@PathVariable int id) {
        boardService.게시글삭제(id);
        return "redirect:/";
    }

5. Service

@Transactional
    public void 게시글삭제(int id) {
        boardRepository.delete(id);
    }
