我解决了这个问题(自定义异常处理程序必须扩展 ResponseEntityExceptionHandler).我的解决方案如下:

I solved the issue (the custom exception handler must extend ResponseEntityExceptionHandler). My solution follows:

        @ControllerAdvice
        public class RestExceptionHandler extends ResponseEntityExceptionHandler {
    
            @Override
            protected ResponseEntity<Object> handleHttpMessageNotReadable(
                HttpMessageNotReadableException ex, HttpHeaders headers,
                HttpStatus status, WebRequest request) {
                // paste custom hadling here
            }
        }
