Question

我必须汇总两条反馈信息。

这是我的代码：

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="AggregateMediator"
       transports="jms"
       statistics="disable"
       trace="disable"
       startOnLoad="true">
   <target>
      <inSequence>
         <log>
            <property name="hi" value="start*************************"/>
         </log>
         <aggregate>
            <completeCondition>
               <messageCount min="2" max="2"/>
            </completeCondition>
            <onComplete expression="//OutboundGTMXML">
               <send>
                  <endpoint>
                     <address uri="jms:/aggregateReciever?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&amp;java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&amp;java.naming.provider.url=tcp://localhost:61616&amp;transport.jms.DestinationType=queue"/>
                  </endpoint>
               </send>
            </onComplete>
         </aggregate>
      </inSequence>
   </target>
   <parameter name="transport.jms.ContentType">
      <rules>
         <jmsProperty>contentType</jmsProperty>
         <default>application/xml</default>
      </rules>
   </parameter>
   <parameter name="transport.jms.Destination">aggregateSender</parameter>
   <description/>
</proxy>

但这不起作用。一旦遇到聚合调解员，它就会停止前进。你能帮帮我，告诉我哪里出错了吗？在此先感谢：）

Answer 1

聚合介体可以与迭代/克隆介体一起使用。你在请求路径中使用它们吗？对于完整条件集min = -1，max = 2

Answer 2

汇总调解员将收集回复。您无法使用聚合调解器聚合入站请求。请参考[1]，这是使用聚合介体+迭代介体的一个很好的例子。 [1] https://docs.wso2.com/display/ESB480/Sample+400%3A+Message+Splitting+and+Aggregating+the+Responses
