Webflux ControllerAdvice - ExceptionHandler 无法调用自定义异常

Question

为了处理 BAD_REQUEST - 从下面的异常处理程序中，总是调用“异常”（500）的异常处理程序，而不是 BadRequestException（400）。 我应该在这里更改什么以使 BadRequestException 被调用？

@RestControllerAdvice(annotations = RestController.class)
public class ExceptionAdvice extends ResponseStatusExceptionHandler {

    @ExceptionHandler(value = BadRequestException.class)
    public ResponseEntity<Offers> handleInputException(BadRequestException badRequestException) {
        Chocolates errorResponse = new Chocolates("", "", Long.valueOf(0), badRequestException.getErrorMessage(), "400");
        return new ResponseEntity<>(errorResponse, HttpStatus.BAD_REQUEST);
    }

@ExceptionHandler(Exception.class)
    public ResponseEntity<Flux<Chocolates>> handleAllOtherException(Exception exception) {
        Flux errorResponse = Flux.just(new Offers("", "", Long.valueOf(0), "Internal Server Error", "Chocolates ill throw an error code"));
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(errorResponse);
    }

Custom Exception class :

public class BadRequestException extends Exception {
    private final String errorMessage;

    public BadRequestException(String errorMessage) {
        this.errorMessage = errorMessage;
    }

    public String getErrorMessage() {
        return errorMessage;
    }
}
