나는 인터넷을 통해 검색 중이며 여러 가지 방법을 시도해 왔지만 제대로 작동하지 못했습니다.아웃 바운드 게이트웨이에서 보낸 사람에게 예외를 throw하는 방법
아웃 바운드 측면에서 throw 된 예외를 catch하는 것이 좋습니다. 예를 들어 일부 유효성 검사는 송신자에게 예외를 반환해야합니다. 이는 성공적으로 전달되지 않았기 때문입니다. DirectChannel을 사용하지 않고 서버에서 요청을 보낼 수 있는지 여부는 알 수 없습니다.
누군가가 나를 도울 수 있기를 바랍니다.
아래 코드에서 SPEL 표현식 인 "checkRemoteOutputHeaders"가있는 필터가 실행될 때 예외를 던지는 SI 구성을 보여줍니다. 다른 변압기 "customJsonToObjectTransformer는"단지 문자열 페이로드를 변환
@Transformer
public Message<ServiceException> transform(ErrorMessage message){
LOGGER.debug("INIT - transform(message=" + message + ")");
MessagingException messageException = (MessagingException) message.getPayload();
ServiceException serviceEx = new ServiceException(messageException.getMessage(), messageException.getCause());
Message<?> originalMsg = messageException.getFailedMessage();
Message<ServiceException> transformedObj = MessageBuilder.withPayload(serviceEx).copyHeaders(originalMsg.getHeaders()).build();
LOGGER.debug("END - transform=" + transformedObj);
return transformedObj;
}
