Spring - Controller에서 @Request, GetMapping 이름이 같으면 생기는 에러

to {GET [/api/board]}: There is already 'boardApiController' bean method
com.toy.board.web.BoardApiController#all() mapped.

 

Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'boardApiController' method 

 

 

RESTful API 만들다가 생긴 오류

    @Autowired
    private BoardRepository boardRepository;



    @GetMapping("/board")

    @GetMapping("/board")

                .orElseGet(() -> {
                    newBoard.setId(id);
                    return boardRepository.save(newBoard);
                });
    }

    @DeleteMapping("/board/{id}")
    void deleteBoard(@PathVariable Long id) {
        boardRepository.deleteById(id);
    }
}

@GetMapping 에 같은 이름이나 주소를 설정했을 때 생기는 오류이다.
