java - Spring-boot:未达到 RestControllerAdvise

Question

我构建了一个RestControlerAdvise:

@RestControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class ExceptionControllerAdvice {

    @ExceptionHandler({DocumentAlreadyExistsException.class})
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public cat.gencat.ctti.canigo.arch.web.rs.model.Error handleException(DocumentAlreadyExistsException e) {

        cat.gencat.ctti.canigo.arch.web.rs.model.Error error = new cat.gencat.ctti.canigo.arch.web.rs.model.Error();
        error.setCode(HttpStatus.BAD_REQUEST.value());
        error.setMessage(e.getMessage());
        return error;

    }

}

尽管如此，即使我提出 DocumentAlreadyExistException，它也从未达到。

启动时检测到:

2018-08-20 17:08:25.791 INFO 4941 --- [ main] .m.m.a.ExceptionHandlerExceptionResolver : Detected @ExceptionHandler methods in exceptionControllerAdvice

有什么想法吗？

我在我的应用程序中运行了相同的代码，并且工作正常，另请注意

@ExceptionHandler methods on the Controller are always selected before those on any @ControllerAdvice instance. It is undefined what order controller-advices are processed.

@RestControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CustomExceptionHandler  {

    @ExceptionHandler(value={Exception.class})
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    public final ErrorMessage exceptionHandler(Exception e)
    {
        ErrorMessage msg=new ErrorMessage();
        msg.setError("its an error");

        return msg;
    }
