如何使用 Mule ESB 过滤出站路由？

我有一个 Mule 实例，配置为处理来自第三方提供商的 xml 响应。最近，提供商已转向新版本，因此更改了 xml 响应。现在我需要一种方法来识别响应是 v1 还是 v2 实现，并调用我这边的适当端点来处理响应。

我目前所拥有的是：

<service name="processResponse">
...
    <outbound>
        <pass-through-router>
            <cxf:outbound-endpoint address="..." clientClass="..." wsdlPort="..." wsdlLocation="..." operation="..."/>
        </pass-through-router>
   </outbound>
</service>

我更愿意在 mule 中添加一个过滤器来识别第 3 方的修订（可能通过响应中的 xml 命名空间），然后调用适当的类。我找不到任何好的例子。

有人可以提供一个如何解决这个问题的例子吗？

I have a instance of Mule that is configured to process xml responses from a third party provider. Recently the provider has moved to a new revision and hence changed the xml response. Now I need a way to identify if the response is a v1 or v2 implementation and call the appropriate endpoint on my side to process the response.

What I have currently is:

<service name="processResponse">
...
    <outbound>
        <pass-through-router>
            <cxf:outbound-endpoint address="..." clientClass="..." wsdlPort="..." wsdlLocation="..." operation="..."/>
        </pass-through-router>
   </outbound>
</service>

I would prefer to add a filter in mule to identify the revision of the 3rd party (perhaps through the xml namespace in the response), and then call the appropriate class. I cannot find any good examples of this.

Can someone provide an example of how this could be solved?

看一下此示例，其中演示了一些版本转换。

我怀疑最直接的方法是使用 xpath 过滤器过滤路由。首先为每个版本定义vm服务。接下来，您将通过具有以下出站端点的服务来过滤它们。包罗万象总是一个好主意。

<outbound>
  <filtering-router>
    <vm:outbound-endpoint ref="Version1"/>
    <expression-filter evaluator="jxpath" expression="/your/version1/xpath/descriminator"/>
  </filtering-router>
  <filtering-router>
    <vm:outbound-endpoint ref="Version2"/>
    <expression-filter evaluator="jxpath" expression="/your/version2/xpath/descriminator"/>
  </filtering-router>
  <forwarding-catch-all-strategy>
    <stdio:outbound-endpoint system="ERR"/>
  </forwarding-catch-all-strategy>
</outbound>

I suspect the most straight forward means is a filtered route using an xpath filter. First define vm services for each version. Next you'll filter to them through a service with following outbound endpoint. A catch all is always a good idea.

<outbound>
  <filtering-router>
    <vm:outbound-endpoint ref="Version1"/>
    <expression-filter evaluator="jxpath" expression="/your/version1/xpath/descriminator"/>
  </filtering-router>
  <filtering-router>
    <vm:outbound-endpoint ref="Version2"/>
    <expression-filter evaluator="jxpath" expression="/your/version2/xpath/descriminator"/>
  </filtering-router>
  <forwarding-catch-all-strategy>
    <stdio:outbound-endpoint system="ERR"/>
  </forwarding-catch-all-strategy>
</outbound>
