在選擇異常策略中捕捉異常策略

我看不到捕捉表達式策略的異常上下文中的causeMatches方法。我在運行時遇到錯誤。我在哪裏可以找到異常上下文對象中的可用方法？我無法找到一個API文檔中 - http://www.mulesoft.org/docs/site/3.8.3/apidocs/在選擇異常策略中捕捉異常策略

請發佈您的XML配置？ – star

沒有你的XML，它只是猜測失敗的原因。但是，這是一個工作異常策略：

<choice-exception-strategy doc:name="Choice_Exception_Strategy"> 
     <catch-exception-strategy when="exception.causeMatches('com.mulesoft.weave.*')" doc:name="Catch Weave"> 
      <logger message="#[message]" level="INFO" doc:name="Logger"/> 
     </catch-exception-strategy> 
     <catch-exception-strategy when="exception.causeMatches('java.lang.Exception')" doc:name="Catch other"> 
      <logger message="#[message]" level="INFO" doc:name="Logger"/> 
     </catch-exception-strategy> 
    </choice-exception-strategy>

如有疑問，請閱讀文檔：https://docs.mulesoft.com/mule-user-guide/v/3.8/catch-exception-strategy

這裏是例外的選擇策略。沒有編譯錯誤，但語法看起來有點不同。

<choice-exception-strategy name="ImplementationChoice_Exception_Strategy"> 
    <catch-exception-strategy 
     when="#[exception.causeMatches('com.mule.weave.*') || exception.message=='Payload is empty.']" 
     doc:name="No flights DW exception"> 
     <set-payload value="No flights too #[flowVars.code + '\n' + exception]" 
      doc:name="Set Payload" /> 
     <set-property propertyName="http.status" value="400" 
      doc:name="Property" /> 
     <logger level="INFO" doc:name="Logger" /> 
    </catch-exception-strategy> 
    <catch-exception-strategy doc:name="Catch Exception Strategy"> 
     <set-payload value="data is not available, try later #['\n' + exception]" 
      doc:name="Set Payload" /> 
     <set-property propertyName="http.status" value="500" 
      doc:name="Property" /> 
     <logger level="INFO" doc:name="Logger" /> 
    </catch-exception-strategy> 
</choice-exception-strategy>
