Java GlobalExceptionHandler始终返回500

我有以下异常处理程序：

@Log4j2
@ControllerAdvice
public class GlobalExceptionHandler {

@ExceptionHandler(Exception.class)
public ResponseEntity handleException(Exception e) {
    logExceptionWithPath("Unhandled general exception", e);
    return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
}

@ResponseBody
@ExceptionHandler({ValidationException.class})
public ResponseEntity<ErrorResponse> handleBindException(ValidationException ex) {
    logExceptionWithPath("Validation exception", ex);
    return new ResponseEntity<>(new ErrorResponse(ex.getMessage()), HttpStatus.BAD_REQUEST);
}


@ResponseBody
@ExceptionHandler({BindException.class})
public ResponseEntity<ErrorResponse> handleBindException(BindException ex) {
    logExceptionWithPath("Bind exception", ex);
    return new ResponseEntity<>(new ErrorResponse(ex.getMessage()), HttpStatus.BAD_REQUEST);
}

@ResponseBody
@ExceptionHandler(AmbiguousTermException.class)
public ResponseEntity<ErrorResponse> handleAmbiguousTermException(AmbiguousTermException ex) {
    logExceptionWithPath("AmbiguousTermException", ex);
    return new ResponseEntity<>(new ErrorResponse(ex.getMessage()), HttpStatus.BAD_REQUEST);
}

在日志中，我总是使用logExceptionWithPath生成消息，因此ExceptionHandler似乎工作正常，但在某个地方存在IOException

每个异常（以及每个@ExceptionHandler）的响应都类似

下面是我的应用程序和spring的一些日志：

这些都是有趣的日志。也许这根本没有连接到Spring，而是它正在运行的服务器？

不管怎样，如果您有任何关于它不起作用的线索，请留下答案或评论。

您必须向方法添加响应状态，如

@ResponseStatus（HttpStatus.NOT_FOUND）

@ResponseBody
@ResponseStatus（HttpStatus.BAD_REQUEST）//添加了此注释
@ExceptionHandler（歧义usterException.class）
公共响应处理模糊ustermexception（模糊ustermexception除外）{
带有路径的LogException（“模糊UsterException”，例如）；
返回新的ResponseEntity（新的ErrorResponse（例如getMessage（）），HttpStatus.BAD_请求）；
}
