Mule-ESB:基于HTTP状态的Mule筛选器 [英] Mule-ESB: Mule filter based on HTTP Status

问题描述

如何使用选择过滤器以外的其他过滤器根据http状态调用子流?

How do I use a filter other than a choice filter to call a subflow based on the http status?

<flow>  
<http:outbound-endpoint exhange-pattern="request-response>
if http.status!=201  
<flow-ref="subflow-to-invoke">  
</flow>
