我将 From Wso2 esb 和负载平衡概念与服务一起使用，但我有一个错误，这是我的代码：

这是我的顺序：

<log level="custom">
  <property xmlns:ns="http://org.apache.synapse/xsd" name="CParam" expression="$ctx:CParam"/>
</log>
<payloadFactory>
  <format>
     <p:MultiService xmlns:p="http://tempuri.org/">
        <!--Exactly 1 occurrence-->
           <s:z xmlns:s="http://tempuri.org/">$1</s:z>
        </p:MultiService>
     </format>
     <args>
        <arg xmlns:ns="http://org.apache.synapse/xsd" expression="$ctx:CParam"/>
     </args>
  </payloadFactory>
  <log level="full"/>
  <send>
     <endpoint>
        <loadbalance algorithm="org.apache.synapse.endpoints.algorithms.RoundRobin">
           <endpoint name="mt">
              <address uri="http://D-N-PC-12071:8280/services/MultiService/MultiService"/>
           </endpoint>
           <endpoint name="KR">
              <address uri="http://D-N-PC-12071:8280/services/Multi/MultiService"/>
           </endpoint>
        </loadbalance>
     </endpoint>
  </send>
</sequence>

当使用负载平衡服务之一返回值 0 和其他返回正确值

我发现我的问题在于定义端点 kr 和 mt 不正确我在多服务中的参数应该与 mt 中的源参数兼容被命名为“z”

       <endpoint name="mt">
          <address uri="http://D-N-PC-12071:8280/services/MultiService/MultiService"/>
       </endpoint>

但是 kr 中的参数被命名为“a”

       <endpoint name="KR">
          <address uri="http://D-N-PC-12071:8280/services/Multi/MultiService"/>
       </endpoint>
