我需要托管SOAP Web服务并为该主Web服务托管代理Web服务... 所以我有以下内容： -
现在我已经创建了暴露的SOAP Web服务并执行了CRUD操作，并且工作正常。现在问题在于代理Web服务..以下是我的代理Web服务配置： -
<flow name="ProxyFlow" doc:name="ProxyFlow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8086" path="proxy/mainData" doc:name="HTTP" />
<cxf:proxy-service port="MainDataPort" namespace="http://services.test.com/schema/MainData/V1" service="MainDataService" payload="body" wsdlLocation="MainData.wsdl" doc:name="SOAP"/>
<mulexml:dom-to-xml-transformer doc:name="DOM to XML"/>
<jms:outbound-endpoint queue="ProxyQueue" connector-ref="Active_MQ" doc:name="JMS" exchange-pattern="request-response"/>
</flow>
<flow name="ClientProxy" doc:name="ClientProxy">
<jms:inbound-endpoint connector-ref="Active_MQ" address="jms://tcp:ProxyQueue" doc:name="JMS" exchange-pattern="request-response" disableTemporaryReplyToDestinations="true" responseTimeout="90000"/>
<byte-array-to-string-transformer doc:name="Byte Array to String"/>
<cxf:proxy-client payload="body" doc:name="SOAP" />
<http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" method="POST" doc:name="HTTP" />
</flow>
现在您可以看到代理Web服务正在使用JMS队列。当我从SOAPUI触发代理Web服务时..我得到以下异常： -

现在我可以发现主要的web服务是在内部调用的，而数据是在DB中创建的。但我想它无法将响应转换回代理客户端..任何建议..
答案 0 :(得分：0)
尝试以下列方式使用代理客户端。
<http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" method="POST" doc:name="HTTP" >
<cxf:proxy-client payload="body" doc:name="SOAP" />
</http:outbound-endpoint>
<logger level="INFO" message="#[message.payloadAs(java.lang.String)]" />
HTTP outbound正在以DepthXMLStreamReader的格式重新启动响应。上面的Proxy-client格式应该有所帮助。记录器将读取StreamReader的响应，因此它是可序列化的格式。
希望这有帮助。
答案 1 :(得分：0)
我意识到Http outbound之后的有效负载是流，所以需要将其转换为String，否则将获得异常。
所以，对我有用的解决方案是： -
<logger level="INFO" message="#[message.payloadAs(java.lang.String)]" />
或者我意识到放<byte-array-to-string-transformer>也会有用
