使用 int-ws:outbound-gateway 上的 spring 集成处理 Http 错误

Question

我在处理 <int-ws:outbound-gateway> 上的 http 错误时遇到问题
我尝试在<int:gateway> 上放置error-channel，但它似乎不起作用，因为我得到了解组异常。
另外我觉得不对，应该是在收到<int-ws:outboung-gateway>的消息后某处发现http错误
我的消息系统是这样设置的：
<int:gateway> -> channel -> transformer -> channel -> <int-ws:outboung-gateway>

问题：使用 spring 集成捕获 http 错误的正确方法是什么？

编辑后

  <int:channel id="checkProcessRequestChannel"/>
  <int:channel id="checkProcessResponseChannel"/>

  <int:channel id="errorChannel"/>

  <!-- channels for connecting to the outbound gateway -->
  <int:channel id="checkProcessOutboundRequestChannel"/>
  <int:channel id="checkProcessOutboundResponseChannel"/>



<int:gateway id="eInvoiceGateway" service-interface="com.iquest.play.integration.einvoice.EInvoiceGateway" error-channel="errorChannel">
    <int:method name="checkProcessByCode" request-channel="checkProcessRequestChannel" reply-channel="checkProcessResponseChannel"/>
<int:gateway>



  <int:transformer ref="eInvoiceTransformer" method="transformCheckProcessRequest" input-channel="checkProcessRequestChannel" output-channel="checkProcessOutboundRequestChannel"/>
  <int:transformer ref="eInvoiceTransformer" method="transformCheckProcessResponse" input-channel="checkProcessOutboundResponseChannel" output-channel="checkProcessResponseChannel"/>



 <int-ws:outbound-gateway id="checkClientByCodeOutboundGW"
                           request-channel="checkProcessOutboundRequestChannel"
                           reply-channel="checkProcessOutboundResponseChannel"
                           marshaller="eInvoiceMarshaller"
                           unmarshaller="eInvoiceMarshaller"
                           destination-provider="eInvoiceUriProvider"
                           message-factory="eInvoiceMessageFactory"
                           />

修复： 因此，在网关上放置error-channel 后，线程卡在某个地方。这是一个非常愚蠢的问题，网关错误通道的 service-activator 的名称是 errorHandler，它可能被 spring 命名空间使用 -> 更改 bean 名称解决了问题。

我们可以在解组期间处理 Spring 集成中的 http 错误。

编写自定义解组器并捕获肥皂错误消息。

这篇文章清楚地解释了如何处理soap错误消息。
