使用以下文件配置，应用程序始终提供 WARN 问题。请参阅下面的日志示例。

连接器按以下方式设置：

<file:connector name="InputFileConnector" doc:name="File Connector" workDirectory="${Processing_Path}" 
            workFileNamePattern="#[message.outboundProperties['originalFilename']]" moveToDirectory="${Archive_Path}" 
            moveToPattern="#[message.outboundProperties['originalFilename']]"
            streaming="true" autoDelete="false" validateConnections="true" fileAge="${FileAge}"/>

入站端点配置：

<file:inbound-endpoint responseTimeout="10000" doc:name="File" path="${Inbound_Path}" pollingFrequency="${PollingFrequency}" connector-ref="InputFileConnector">
            <!-- Add filename-regex-filter to insure files are there to kick off the process -->
            <file:filename-regex-filter pattern="SAMPLE\d+\.FILE" caseSensitive="true"/>
        </file:inbound-endpoint>

我正在寻找有关导致 Mule 出现此 WARN 问题的任何见解或建议。

更新将流属性更改为 false，解决了 WARN 问题。

Mule 在流文件端点方面存在一些问题，因此您可以streaming="false"在连接器中尝试您的应用程序。我不知道 Mule 文件流式传输到底发生了什么，但我猜它可能类似于打开文件句柄，当文件从处理列表中删除时会产生异常。
