Question

我在<int-ws:outbound-gateway>上处理http错误时遇到问题我尝试在error-channel上放置<int:gateway>，但它似乎不起作用，因为我得到了解组异常。
另外我觉得这不对，在收到来自<int-ws:outboung-gateway>的消息后，应该在某处抓到http错误我的消息系统设置如下：
<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"
                           />

FIX： 因此，在网关上放置error-channel之后，线程就会卡在某处。这是一个非常虚拟的问题，网关错误通道service-activator的名称是errorHandler，它可能被spring命名空间使用 - ＆gt;更改bean名称解决了问题。

我们可以在unmarshal期间处理spring集成中的http错误。

编写自定义unmarshaller并捕获soap错误消息。

本文清楚地解释了如何处理肥皂故障信息。

 <bean id="hmzJaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
         <property name="contextPaths">
                <list>
                    <value>org.hmz.request.types</value>
                </list>
            </property>
        </bean>
<bean id="custJaxbUnMarshaller" class="com.jay.hmz.util.CustJaxbUnMarshaller" >
     <property name="contextPaths">

                <value>org.hmz.request.types</value>
            </list>
        </property>
    </bean>

    <int:chain input-channel="channel.in" output-channel="channel.out"> 
         <int:transformer method="transformParentRequestById"><bean class="org.jay.hmz.api.transformers.OrderTransformer"/></int:transformer>
         <int-ws:header-enricher><int-ws:soap-action value="${order.request.uri}"/></int-ws:header-enricher> <int-ws:outbound-gateway interceptors="hmzSecurityInterceptor" mapped-request-headers="GUID, USER_REF" request-callback="hmzWebServiceMessageCallback" unmarshaller="custJaxbUnMarshaller" marshaller="hmzJaxbMarshaller" uri="${order.request.uri}"/> 
         <int:transformer method="transformRetrieveParentOrderResponse"><bean class="org.jay.hmz.api.transformers.OrderTransformer"/></int:transformer> 
     </int:chain>

    <int:service-activator input-channel="requestErrorChannel" output-channel="response.out" ref="requestErrorHandler" method="handleFailedOrderRequest"/>

    <bean id="requestErrorHandler" class="org.jay.hmz.api.errorhandler.RequestErrorHandler"/>

public class CustJaxbUnMarshaller extends Jaxb2Marshaller {

    @Override
    public Object unmarshal(Source source, MimeContainer mimeContainer)
            throws XmlMappingException {
        LOGGER.debug("Inside Custom JaxbWrapper unmarshal");
        Object mimeMessage = new DirectFieldAccessor(mimeContainer)
                .getPropertyValue("mimeMessage");
        Object unmarshalObject = null;
        if (mimeMessage instanceof SaajSoapMessage) {
            SaajSoapMessage soapMessage = (SaajSoapMessage) mimeMessage;
            String faultReason = soapMessage.getFaultReason();
            if (faultReason != null) {
                throw convertJaxbException(new JAXBException(faultReason));
            } else {
                unmarshalObject = super.unmarshal(source, mimeContainer);
            }
        }
        return unmarshalObject;
    }
}
