Question

在休息应用程序中，我创建了一个用于管理错误的类

<!-- #include virtual="/path/to/includes/filename.inc" -->

}

在我的服务层

@ControllerAdvice
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(ProcessPaymentException.class)
    private ResponseEntity < String > handleProcessPaymentException(ProcessPaymentException e) {
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
    }

    @ExceptionHandler(Exception.class)
    private ResponseEntity < String > defaultExceptionHandler(Exception e) {
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(e.getMessage());
    }

当我得到@Transactional @Override public void processPayment(Long paymentId, PaymentModeEnum paymentMode) throws ProcessPaymentException { processCreditCardPayment(paymentId, paymentMode); } private void processCreditCardPayment(Long paymentId, PaymentModeEnum paymentMode) throws ProcessPaymentException { try{ chargePayment(paymentId) }catch(ProcessPaymentException ppe){ throw new ProcessPaymentException(ppe.getMessage()); #1 } } private ResolverReceipt chargeMemberCreditCard(Long paymentId, PaymentGatewayConfig paymentGateway) throws ProcessPaymentException { ... if(memberId==null){ throw new ProcessPaymentException("error process payment");#2 } }时，我在调试模式下看到，当我进入ProcessPaymentException时，我经过RestResponseEntityExceptionHandler。我不明白为什么，我想通过defaultExceptionHandler方法。

我看到的调试信息是：

handleProcessPaymentException

我想要得到：Target object must not be null; nested exception is java.lang.IllegalArgumentException: Target object must not be null. e= (org.springframework.dao.InvalidDataAccessApiUsageException) org.springframework.dao.InvalidDataAccessApiUsageException: Target object must not be null; nested exception is java.lang.IllegalArgumentException: Target object must not be null

根据this文章，如果您使用了自定义解析程序，则需要定义以下行以使用@ExceptionHandler。

@Component
public class AnnotatedExceptionResolver extends AnnotationMethodHandlerExceptionResolver
{
    public AnnotatedExceptionResolver() {
        setOrder(HIGHEST_PRECEDENCE);
    }
}

ControllerAdvice中未正确报告嵌套异常
