WSO2聚合调解器过早/不完整/未知完成

我的聚合中介在代理的外部序列中遇到了一个令人困惑的问题

配置：

实现迭代中介器的序列迭代了以下消息：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
        <productSearchRs xmlns="SHC">
            <productDetails>
                <Product_ID>1487326</Product_ID>
                <Product_Name>SECRET</Product_Name>
                <Product_Size>M</Product_Size>
                <Product_Colour>BLACK</Product_Colour>
                <Product_Type>SOCKS</Product_Type>
                <Source>SHC</Source>
            </productDetails>
            <productDetails>
                <Product_ID>1985211</Product_ID>
                <Product_Name>SECRET</Product_Name>
                <Product_Size>M</Product_Size>
                <Product_Colour>BLACK</Product_Colour>
                <Product_Type>SOCKS</Product_Type>
                <Source>SHC</Source>
            </productDetails>
        </productSearchRs>
    </soapenv:Body>
</soapenv:Envelope>

编辑：

使用带有序列键的“发送”中介和“序列”中介有什么区别

此外，我可以使用单个“聚合”节点可靠地聚合一个序列中“迭代”的响应和来自不同序列的响应吗？似乎我的聚合节点在收集所有响应之前过早地“完成”，因此执行我的发送/响应（这里有什么区别？）中介。因为我在文档中注意到了这一点：

 Note that when the Iterate mediator is used to split the requests and produces only an n number of fragmented messages, the Aggregate mediator will terminate as soon as it receives n responses, even if you have specified a higher minimum limit.

启用可靠的消息传递会给我带来各种其他问题

在序列“PocsearchHandlerSeq”中，您应该在聚合的onComplete节点内返回聚合响应：

<?xml version="1.0" encoding="UTF-8"?>
<sequence xmlns="http://ws.apache.org/ns/synapse" name="pocSearchRsHandlerSeq">
    <aggregate>
        <completeCondition>
            <messageCount min="-1" max="-1"/>
        </completeCondition>
        <onComplete xmlns:ns="http://org.apache.synapse/xsd" expression="//productDetails">
            <payloadFactory media-type="xml">
                <format>
                    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:prod="http://za.co.pepkor/product_service/">
                        <soapenv:Body>
                            <prod:productSearchResp>$1</prod:productSearchResp>
                        </soapenv:Body>
                    </soapenv:Envelope>
                </format>
                <args>
                    <arg xmlns:ns="http://org.apache.synapse/xsd" evaluator="xml" expression="//productDetails"/>
                </args>
            </payloadFactory>
            <send/>
        </onComplete>
    </aggregate>
</sequence>

$1

我是这样解决的：

事实证明，我需要一个特定的聚合器来聚合我的迭代消息（分别通过迭代/聚合节点上的id属性链接），然后另一个聚合器来聚合其他响应以及上面的响应（已经聚合的响应）

我的响应处理程序：

我试过那件牛仔裤，但仍然得到不同的回应。我想问几个问题：Jean由于某种原因，消息正在重置为
