DSL中出站网关出现故障时路由到错误信道

裴卓君
2023-03-14

我有以下Spring Integration JAva DSL代码：

    return flow -> flow.channel(INPUT_CHANNEL)
            .transform(customMapper, "mapFrom")
            .enrichHeaders(polarisPreCompSoapActionHeader())
            .route("headers.key",
                    subflowMapping -> subflowMapping
                            .subFlowMapping("value1", subflow -> subflow
                                    .handle(webserviceOutboundGateway,
                                            e -> e.advice(skipAdvice()))
                            )
            )
            .channel(OUTPUT_CHANNEL);

@Bean
public Advice skipAdvice() {
    ExpressionEvaluatingRequestHandlerAdvice advice = new ExpressionEvaluatingRequestHandlerAdvice();
    advice.setFailureChannel(errorChannel());
    return advice;
}

WebServiceOutboundGateway创建为MarshallingWebServiceOutboundGateway的bean。

我试图实现的是，当SOAP错误到达时，将错误消息路由到错误通道。我认为我可以向处理程序添加一个建议，这个建议应该是ExpressionEvaluatingRequestHandlerAdvise，我可以在其中设置失败通道。因此，每当出站网关中抛出错误时，错误消息将被转发到错误通道。

我将trapExecution设置为false，直接将通知添加到网关，并且必须使用SetonFailureExpressionString，否则流将挂起。所以现在看起来是这样的：

@Bean
@Autowired
public MarshallingWebServiceOutboundGateway webserviceOutboundGateway(...) {
    MarshallingWebServiceOutboundGateway gateway = new ...;
    gateway.setAdviceChain(Arrays.asList(skipAdvice()));
    return gateway;
}

@Autowired
@Qualifier("skipCallChannel")
private MessageChannel skipCallChannel;

@Bean
public Advice skipAdvice() {
    ExpressionEvaluatingRequestHandlerAdvice advice = new ExpressionEvaluatingRequestHandlerAdvice();
    advice.setFailureChannel(endChannel);
    advice.setOnFailureExpressionString("payload + ' was bad, with reason: ' + #exception");
    advice.setTrapException(true);
    return advice;
}

我得到以下错误：

我认为必须添加通道才能成功执行，但我不想这样做，因为它已经在处理程序所在的流中定义了（请参见.channel(OUTPUT_CHANNEL))。我可以在建议中只设置故障通道吗？
谢谢！

enrice.acmerequest.output通道是acmerequestenricher的应答通道。我的意图是，如果没有错误，那么执行流中的所有任务，但是如果acmeprecompenricher中有SOAP错误，那么跳过mlrequestenricher和mlenricher直接转到acmerequestenricher。
我认为问题是在faul场景中，SI看不到订阅了acmerequestenricher...？在这种情况下我能做什么？

请参阅ExpressionEvaluatingRequestHandlerAdvision上的此方法：

/**
 * If true, any exception will be caught and null returned.
 * Default false.
 * @param trapException true to trap Exceptions.
 */
public void setTrapException(boolean trapException) {

因此，将其设置为true以避免异常重新引发。

请参阅文档：https://Docs.spring.io/spring-integration/Docs/5.3.0.release/reference/html/messaging-endpoints.html#expression-advision
