输入请求：
[
{
"id" : "1",
"make" : "NAHB"
},
{
"id" : "2",
"make" : "Honda"
},
{
"id" : "3",
"make" : "Samsung"
}
]
我正在使用iterate，将上面数组的每个元素作为请求发送到后端服务（在myactual项目中，这不是那么简单的服务，即它的响应非常复杂，有很多数组和子数组（子数组）为了更好地理解问题，我保持这样。）
后端服务的响应由AggregateMediator汇总在一个soap xml中。
以下是AggregateMediator的回复
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<Information>
<jsonObject>
<id>3</id>
<name>Mobile</name>
<model>S8</model>
</jsonObject>
<jsonObject>
<id>2</id>
<name>Car</name>
<model>Amaze</model>
</jsonObject>
<jsonObject>
<id>1</id>
<name>Home</name>
<area>5000sqft</area>
</jsonObject>
</Information>
</soapenv:Body>
</soapenv:Envelope>
我想使用输入请求丰富上面的AggregateMediator响应。 即我想合并输入请求和后端服务的输出。（id在它们之间是常见的。）
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<Information>
<jsonObject>
<id>3</id>
<name>Mobile</name>
<model>S8</model>
<make>Samsung</make>
</jsonObject>
<jsonObject>
<id>2</id>
<name>Car</name>
<model>Amaze</model>
<make>Honda</make>
</jsonObject>
<jsonObject>
<id>1</id>
<name>Home</name>
<area>5000sqft</area>
<make>NAHB</make>
</jsonObject>
</Information>
</soapenv:Body>
</soapenv:Envelope>
我在调用后端服务之前将输入请求数组保留在属性中，并且能够在响应流中访问它。 但问题是“请求和响应都是数组”。我怎样才能在两个不同的数组上同时运行两个foreach，并在更新响应的每个数组元素之前匹配它们的id。

这是一个高级答案;我想你可以自己解决这些细节：
我希望有所帮助。
