我正在尝试使用持久队列的vm传输;这是连接器配置:
<vm:connector
name="vmConnector"
createMultipleTransactedReceivers="true"
numberOfConcurrentTransactedReceivers="20">
<vm:queue-profile maxOutstandingMessages="50000">
<file-queue-store/>
</vm:queue-profile>
</vm:connector>
传输工作正常并且传输.msg文件正在.mule的相应子目录中累积。现在,如果我杀死VM(或者定期关闭mule实例),然后重新启动mule和我的应用程序,我会期望消耗当前队列中的消息,但事实并非如此。
我明白了吗?我认为这种行为将是使用持久队列的一个原因。或者我的配置有问题?这是我可以从文档中收集到的所有内容,但我可能错过了一些内容。
编辑:在进一步检查时,我在申请日志中发现了以下投诉:
