重新啓動後ActiveMQ 5.13.2消息丟失

我是新來的活動MQ。安裝了activemq 5.13.2。在activeMQ服務器重新啓動後，我正在丟失所有消息（包括持久主題）。請在激活的MQ服務器重新啓動之前和之後找到以下控制檯屏幕截圖。重新啓動後ActiveMQ 5.13.2消息丟失

before activeMQ restart

After ActiveMQ restart

這是我的activemq.xml中配置：

消息是否標記爲永久？（請參閱http://activemq.apache.org/why-do-i-not-receive-messages-on-my-durable-topic-subscription.html） – mjn

正如@mjn所述 - 消息在默認情況下是非持久性的，如果從Web控制檯發送。對於從應用程序發送的消息，請仔細檢查您的代碼 –

您確定在重新啓動後不會因爲任何原因清除了「$ {activemq.data}/kahadb」目錄嗎？ – yegodm
