WSO2 ESB，如何使用聚合介体或任何其他介体合并2条消息

Question

我是WSO2 Enterprise Integrator的新手。
我很难使用集结的调解器来合并这两个消息。
我已将第一条消息放在属性中，以便可以访问各个值（还有其他方法吗？）
所需的输出为json格式。 （我尝试过for each，但它仅循环出现在消息2循环消息中。）

输入消息1：

{
  "customerId": "ABC123",
  "channelNo": "1",
  "codename": "code123"
}

输入消息2：

{
  "lnsAcctInfo": [
    {
      "acctno": "101991100000012",
      "custid": "2018111400000002",
      "acctype": null,
      "ccy": null,
      "name": null,
      "prdcode": "300"
    },
    {
      "acctno": "101991100000022",
      "custid": "2018111400000052",
      "acctype": 1,
      "ccy": 1,
      "name": 1,
      "prdcode": "300"
    }
  ]
}

需要的输出：

{
  "customerId": "ABC123",
  "codename": "code123",
  "lnsAcctInfo": [
    {
      "acctno": "101991100000012",
      "custid": "2018111400000002",
      "acctype": null
    },
    {
      "acctno": "101991100000022",
      "custid": "2018111400000052",
      "acctype": 1
    }
  ]
}

这是突触代码：

<resource methods="POST" uri-template="/foreach">
  <inSequence>
    <log>
      <property expression="json-eval($)" name="RecievedPostMessage" />
    </log>
    <property name="customid" scope="default" type="STRING" value="sampleuserid" />
    <payloadFactory description="payload-xml" media-type="xml">
      <format>
        <lnsAcctInfo xmlns="">$1</lnsAcctInfo>
      </format>
      <args>
        <arg evaluator="json" expression="$.lnsAcctInfo[*]" />
      </args>
    </payloadFactory>
    <log>
      <property expression="." name="payload1" />
    </log>
    <iterate expression="//lnsAcctInfo/jsonElement" id="1">
      <target>
        <sequence>
          <log>
            <property expression="." name="Iterate" />
          </log>
          <aggregate>
            <completeCondition>
              <messageCount max="-1" min="-1" />
            </completeCondition>
            <onComplete expression="//jsonElement">
              <log>
                <property expression="." name="aggre" />
              </log>
            </onComplete>
          </aggregate>
        </sequence>
      </target>
    </iterate>
    <log>
      <property expression="." name="overall" />
    </log>
    <respond />
  </inSequence>
  <outSequence>
    <send />
  </outSequence>
  <faultSequence />
</resource>
