Mule フローにエラー処理ロジックを実装しようとしており、HTTP ステータス コードをテストしたいと考えています。私はメッセージフィルターを実装しており、スローcatch-exception-strategyをキャッチしたいのですが、それは可能ですが、ほとんどネストしたいのですが、それができないことがわかっているので、ロジックステートメントを次のように組み合わせています次のような操作:org.mule.api.routing.filter.FilterUnacceptedExceptionmessage-property-filterAND

<catch-exception-strategy when="#[exception.causedBy(org.mule.api.routing.filter.FilterUnacceptedException) &amp;&amp; header:INBOUND:http.status=404]" doc:name="Catch Exception Strategy">

ヒットしたときにこれがフローでエラーを引き起こしている方法:

Mule でこのタイプのロジックを実装する方法はありますか?

問題は、式エバリュエーターを混合していることです。when句は次のようになります。

<catch-exception-strategy when="#[exception.causedBy(org.mule.api.routing.filter.FilterUnacceptedException) and message.inboundProperties['http.status']=404 ]" doc:name="Catch Exception Strategy">

ここでは、 MELに関するドキュメントを見つけることができます
