게시판에 검색기능을 넣으려고 하는데





컨트롤러 부분



@GetMapping("/paging")
public String paging(@RequestParam(required = false, defaultValue = "") String searchKeyword,
 @PageableDefault(page = 1, size=10, sort="id", direction = Sort.Direction.DESC) Pageable pageable,
 Model model) {

Page<BoardDTO> boardList = null;

 if (searchKeyword == null || searchKeyword.isEmpty()) {
boardList = boardService.paging(pageable);
 } else {
boardList = boardService.boardSearchList(searchKeyword, pageable);
 }
int blockLimit = 3;
 int startPage = (((int) (Math.ceil((double) pageable.getPageNumber() / blockLimit))) - 1) * blockLimit + 1;
 int endPage = ((startPage + blockLimit - 1) < boardList.getTotalPages()) ? startPage + blockLimit - 1 : boardList.getTotalPages();

 model.addAttribute("boardList", boardList);
 model.addAttribute("startPage", startPage);
 model.addAttribute("endPage", endPage);
 model.addAttribute("searchKeyword", searchKeyword);

 return "/board/paging";
}




레파지토리 제목으로 찾는 구간


public interface BoardRepository extends JpaRepository<BoardEntity, Long> {
// update board_table set board_hits=board_hits+1 where id=?
 @Modifying
 @Query(value = "update BoardEntity b set b.hit=b.hit+1 where b.id=:id")
void updateHits(@Param("id") Long id);

 Page<BoardEntity> findByTitleContaining(String searchKeyword, Pageable pageable);


 }




서비스구간



public Page<BoardDTO> boardSearchList(String searchKeyword, Pageable pageable) {
log.info("searchKeyword: " + searchKeyword);
 if (searchKeyword == null) {
return Page.empty();
 }
Page<BoardEntity> boardEntities = boardRepository.findByTitleContaining(searchKeyword, pageable);
 return boardEntities.map(board -> new BoardDTO(board.getId(), board.getBoardWriter(), board.getTitle(), board.getHit(), board.getCreatedTime(), board.getUpdatedTime()));
}



이러는데 검색결과가 안나와요 뭐가 문제일까요?
