问题描述

如何处理基于201或503的Jersey Rest服务响应?我可以混合使用groovy和其他评估者吗?在我的示例中，部分使用了消息属性和其他常规用法

How can I process a Jersey Rest Service Response based on 201 or 503? Can I mix groovy and other evaluators? In my example, part is using message properties and other groovy

<flow> 
    <http:outbound-endpoint address="${host}" exchange-pattern="request-response"/>
    <when expression="message:INBOUND:http.status==201">  
    <flow-ref name=="flow2">  
    <when expression="message:INBOUND:http.status==503">  
    <flow-ref name="flow3">
    <when expression="payload instanceof java.lang.SocketException" evaluator="groovy">
    <flow-ref name="flow4">  
</flow>  

推荐答案

您可以使用 MEL 语法.

choice也需要一个otherwise块，在这种情况下决定要执行的操作.

choice needs an otherwise block also, decide what you want to do in that case.

<flow> 
    <http:outbound-endpoint address="${host}" exchange-pattern="request-response"/>
    <choice>
         <when expression="#[message.inboundProperties['http.status']==201]">  
             <flow-ref name=="flow2">  
         </when>
         <when expression="#[message.inboundProperties['http.status']==503]">  
             <flow-ref name="flow3">
         </when>
         <when expression="#[exception instanceof java.net.SocketException]">
             <flow-ref name="flow4">  
         </when>
         <otherwise>
         <!-- decide what you want to do here -->
         </otherwise> 
     </choice>
</flow>
