[@ jackson的InvalidFormatException的ExceptionHandler

Question

在spring-boot应用程序中，我想使用通用的异常处理程序来捕获和处理com.fasterxml.jackson.databind.exc.InvalidFormatException -Exception，并在遇到一个异常时返回400。

是，不调用该异常的异常处理程序。而是返回一个偶然的500错误。

我想念的是什么？这是否与InvalidFormatException是嵌套异常有关？我该如何解决？

代码-异常处理程序

@ControllerAdvice(basePackages = "packe.path.to.rest.controllers")
public class GeneralExceptionHandler {

   // .. other working exception handlers...

@ExceptionHandler(InvalidFormatException.class)
    public ResponseEntity<ErrorMessage> processJsonInvalidFormatException(InvalidFormatException e) {
        log.error("Invalid Json Format Exceptioon occurred");

        HttpStatus status = HttpStatus.BAD_REQUEST;
        ErrorMessage msg = new ErrorMessage(
            status.value(),
            status.getReasonPhrase(),
            e.getMessage()
        );

        return new ResponseEntity(msg, status);
    }
