[홈페이지 제작] 익명 페이지 2 - 익명 글쓰기

1. View

2. DTO 생성

public class BoardRequest {

    @Data
    public static class saveDTO{
        private String author ;
        private String title ;
        private String content ;
	}
}

3. 컨트롤러

@GetMapping("/board/saveForm")
    public String saveForm() {
        return "board/saveForm";
}

@PostMapping("/board/save")
    public String save(BoardRequest.saveDTO requestDTO,HttpServletRequest request){
				// 유효성 검사
        if(requestDTO.getTitle().length()>20){
            request.setAttribute("status",400);
            request.setAttribute("msg","제목은 20자를 넘을 수 없습니다.");
            return "error/40x";
        }

        if(requestDTO.getContent().length()>20){
            request.setAttribute("status",400);
            request.setAttribute("msg","내용은 20자를 넘을 수 없습니다.");
            return "error/40x";
        }

				//DTO 를 레파지토리에 전달
        boardRepository.save(requestDTO);

        return "redirect:/";
    }

3. 레파지토리

@Transactional
    public void save(BoardRequest.saveDTO requestDTO) {
        Query query = em.createNativeQuery("insert into board_tb(author,title,content) values (?,?,?)");
        query.setParameter(1,requestDTO.getAuthor());
        query.setParameter(2,requestDTO.getTitle());
        query.setParameter(3,requestDTO.getContent());
        query.executeUpdate();
    }
