Question

我使用spring boot并开始管理错误。

我创建了一个异常处理来处理未找到的资源。

@ControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(ResourceNotFoundException.class)
    private ResponseEntity<Void> handleResourceNotFoundException(ResourceNotFoundException e) {
        return ResponseEntity.notFound().build();
    }
}

在我的控制器中我做了

@RequestMapping(value = "/members/{memberId}", method = RequestMethod.GET)
public ResponseEntity getMemberById(@PathVariable("memberId") Long memberId) throws ResourceNotFoundException {
    MemberDto memberDto = memberService.getMemberById(memberId);
    return new ResponseEntity(memberDto, HttpStatus.OK);
}

@Override
public MemberDto getMemberById(Long memberId) throws ResourceNotFoundException {
    Member member = memberRepository.findOne(memberId);

    if (member == null) {
        throw new ResourceNotFoundException("Member not found");
    }

    return convertToMemberDto(member);
}

我只有几个成员，所以如果我打电话

本地主机：/构件/ 999

我在响应标题中看到chrome

HTTP/1.1 404 Not Found

为什么我没有收到消息：找不到会员？ 这是使用spring boot管理错误的好方法吗？如何在控制器中管理不同类型的错误？

您需要更改异常处理程序以返回包含您要返回的错误消息的正文，即：

@ControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(ResourceNotFoundException.class)
    private ResponseEntity<Void> handleResourceNotFoundException(ResourceNotFoundException e) {
          // log exception
          return ResponseEntity
            .status(HttpStatus.FORBIDDEN)
            .body("Member not found");
    }
}

处理ResourceNotFoundException，消息不好
