我陷入了一个非常小的问题 我想在消息过滤器下包装 idempotent-message-filter 这是我的流程： -
<idempotent-message-filter name="Validation" idExpression="#[message:payload]" doc:name="Idempotent Message">
<simple-text-file-store directory="./idempotent" />
</idempotent-message-filter>
<flow name="tttFlow1" doc:name="tttFlow1">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" path="path" doc:name="HTTP"/>
<message-filter onUnaccepted="ValidationFailFlow" doc:name="filter to validate xml" throwOnUnaccepted="true" >
<filter ref="Validation"/>
</message-filter>
<logger message="Passed" level="INFO" doc:name="Logger"/>
<set-payload value="Passed" doc:name="Set Payload"/>
<catch-exception-strategy doc:name="Catch Exception Strategy">
<set-payload value="EXCEPTION!" doc:name="Set Payload" />
</catch-exception-strategy>
</flow>
获得以下例外： -

所以，我的问题很简单： -
答案 0 :(得分：1)
我认为idempotent-message-filter实际上是一个拦截消息处理器而不是过滤器（实现org.mule.api.routing.filter.Filter.class），所以它不能在消息过滤器中使用。
但是，看起来您正在将其用于throwOnUnaccepted功能。 idempotent-message-filter本身具有此属性，因此不需要：
<idempotent-message-filter name="Validation" idExpression="#[message:payload]" throwOnUnaccepted="true" />
答案 1 :(得分：0)
感谢Ryan，所以我的工作解决方案是： -
<idempotent-message-filter idExpression="#[message:payload]" doc:name="Idempotent Message" throwOnUnaccepted="true" onUnaccepted="ValidationFailFlow">
<simple-text-file-store directory="./idempotent" /> <!-- In memory files -->
</idempotent-message-filter>
