Web services 如何在使用Mule负载将数据发布到Web服务后在客户端设置响应

我有一个2骡流量：- …第一个流公开执行DB CRUD操作的SOAP Web服务。。。我的第一个流程是：-

<flow name="ServiceFlow" doc:name="ServiceFlow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" doc:name="HTTP"/>
<cxf:jaxws-service  serviceClass="com.test.services.schema.maindata.v1.MainData"  doc:name="SOAP"/>
<component class="com.test.services.schema.maindata.v1.Impl.MainDataImpl" doc:name="JavaMain_ServiceImpl"/>
</flow>

    <flow name="ClientFlow" doc:name="ClientFlow">
            <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8888" path="clientpath" doc:name="HTTP"/>

    <set-payload doc:name="Set Payload" value="#[import com.test.services.schema.maindata.v1.*; dRequest = new DataRequest();dRequest.id = 7;dRequest.age = 55;dRequest.name = 'aValue';dRequest.designation = 'hhhhh'; dRequest]"/>

     <async doc:name="Async">
    <mulexml:object-to-xml-transformer doc:name="Object to XML"/>
    <logger message="payload :- #[message.payload]" level="INFO" doc:name="Logger"/>
    </async>

    <cxf:jaxws-client doc:name="SOAP" serviceClass="com.test.services.schema.maindata.v1.MainData" operation="insertDataOperation" port="MainDataPort" />  

 <http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" doc:name="HTTP" method="POST"/>

</flow>

---

更新流：- 我已经使用Java组件为客户端流设置响应，它工作正常，没有任何问题…：-

<flow name="ClientFlow" doc:name="ClientFlow">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8888" path="aa" doc:name="HTTP"/>

<set-payload doc:name="Set Payload" value="#[import com.test.services.schema.maindata.v1.*; dRequest = new DataRequest();dRequest.id = 7;dRequest.age = 55;dRequest.name = 'aValue';dRequest.designation = 'hhhhh'; dRequest]"/>

<http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" doc:name="HTTP">
<cxf:jaxws-client doc:name="SOAP" serviceClass="com.test.services.schema.maindata.v1.MainData" operation="insertDataOperation" port="MainDataPort" />
</http:outbound-endpoint>
<custom-transformer class="com.test.request.ResponseTransformer" doc:name="JavaTransformerForResponse"/> <!-- Response Java Class -->
<mulexml:object-to-xml-transformer doc:name="Object to XML"/>
<logger message="#[message.payload]" level="INFO" doc:name="JSON Logging"/>
</flow>

现在它工作正常，日志中的响应是：-

Now Entering Method:: com.test.services.schema.maindata.v1.Impl.MainDataImpl.insertDataOperation() *****
Data inserted Successfully
[2014-07-31 13:06:23,150] [INFO ] [[SOAPHeaderInterceptor].connector.http.mule.default.receiver.04] <com.test.services.schema.maindata.v1.DataResponse>
  <response>Data inserted Successfully</response>
  <id>0</id>
  <age>0</age>
</com.test.services.schema.maindata.v1.DataResponse>

现在进入Method:：com.test.services.schema.maindata.v1.Impl.MainDataImpl.insertDataOperation（）*****
数据插入成功
[2014-07-31 13:06:23150][INFO][[SOAPHeaderInterceptor].connector.http.mule.default.receiver.04]

但我不想使用Java组件来响应。。请建议如何在Mule中使用setpayload或表达式设置它。。。请帮助..

您可以删除

自定义转换器，因为它实际上对您没有任何用处

我相信原文：

无法将类型“com.test.services.schema.maindata.v1.DataResponse”封送为元素，因为它缺少@XmlRootElement注释

这个问题是由于Mule需要一种方法将
cxf:jaxws客户机
中的
DataResponse
对象封送到一个可以通过HTTP返回给调用方的表单

通过向xml转换器添加
mulexml:object
提示Mule如何封送它，解决了这个问题（即，不要使用JAXB，因为它无法工作，而是使用XStream）因此，根据David的建议，最终的解决方案是使用
对象到json transformer
或
对象到xml transformer
或
对象到字符串transformer
任何一个都可以在这里用来封送响应对象
这是JAXB封送问题，所以我认为它在服务器端，对吗？服务工作正常吗当您使用SOAPui测试它时？是的..服务工作正常David…问题仅来自客户端流..即使在触发客户端流时也是如此。数据已成功发布到主服务（ServiceFlow）数据被插入到数据库中，但异常在最后被抛出..我猜是客户端流无法生成响应..请查看SOAP响应..存在根对象insertDataResponse..在异常中无法封送根对象..我想我需要以相同的方式设置负载对于出站端点之后的响应..但我不知道如何做..是否有任何方法可以在客户端中显示来自主服务的响应消息？是否需要在客户端中的出站端点之后设置DataResponse对象？是否尝试注释掉
async
块以查看这是否会导致问题？另一个问题是当Mule构建
ClientFlow
的响应时，可能会产生e：您希望Mule如何序列化响应对象，以便通过HTTP提供服务？我不明白：
自定义转换器对负载没有任何作用（它获取并设置它，因此它是noop），但它将响应内容类型设置为“text/html”，尽管响应是XML。你真的确定这个
自定义转换器是必要的吗？如果删除它会发生什么？是的，David，object-to-xml transformer或object-to-json transformer或object-to-string transformer。。。这里可以使用任何一个来封送响应对象。。谢谢你，大卫。。
