Question

我编写了一个代理来汇总来自不同DSS服务的消息，并将所有内容组合到一个响应中。代理配置如下

                        expression="/s11:Envelope/s11:Body/child::*[position()=1] | /s12:Envelope/s12:Body/child::*[position()=1]">

         </aggregate>
      </outSequence>
   </target>
   <parameter name="enableMTOM">false</parameter>

</proxy>

我得到的回应是

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
   <soapenv:Body>
      <result xmlns="http://ws.wso2.org/dataservice">
         <id>1</id>
         <name>meeran</name>
      </result>
      <result xmlns="http://ws.wso2.org/dataservice">
         <designation>engineer</designation>
         <level>B2</level>
      </result>
      <result xmlns="http://ws.wso2.org/dataservice">
         <age>26</age>
         <exp>3</exp>
      </result>
   </soapenv:Body>
</soapenv:Envelope>

但我回答的是

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
       <soapenv:Body>
          <result xmlns="http://ws.wso2.org/dataservice">
             <id>1</id>
             <name>meeran</name>          
             <designation>engineer</designation>
             <level>B2</level>          
             <age>26</age>
             <exp>3</exp>
          </result>
       </soapenv:Body>
    </soapenv:Envelope>

如何实现上述回应？我应该在聚合调解员之后使用什么调解员。请帮忙。

Answer 1

在aggregate / onComplete内部，在发送之前，您可以使用xslt mediatior并在xsl中，在结果节点上定义模板并复制它的所有子项。

wso2 esb聚合和响应丰富
