我有一个特殊问题
我开发了一个ServletContextListener，用于在应用程序启动时在队列上创建消息监听器，并在应用程序中停止（接收器，会话和连接）消息监听器，如下所示
public class AppContextListener implements ServletContextListener {
private static JMSQueue updateIssueOrderApprovalQueue;
private static JMSQueue rejectIssueRequestQueue;
public void contextInitialized(ServletContextEvent p1) {
updateIssueOrderApprovalQueue = IssueOrderApprovalOperationsListener.registerUpdateIssueOrderApprovalQueueListener();
rejectIssueRequestQueue = RejectIssueRequestOperationsListener.rejectIssueRequestQueueListener();
}
public void contextDestroyed(ServletContextEvent event) {
try{
if(updateIssueOrderApprovalQueue != null)
updateIssueOrderApprovalQueue.close();
} catch(Exception e){
e.printStackTrace();
}
try{
if(rejectIssueRequestQueue != null)
rejectIssueRequestQueue.close();
} catch(Exception e){
e.printStackTrace();
}
}
}
代码工作正常，没有。当我停止应用程序时，Wildfly控制台中的消费者减少了 但是服务器控制台包含一些奇怪的错误，如下所示

我认为服务器仍然有活动线程等待消息来调用我的监听器，当他检查我的监听器时，线程找不到监听器，因为我已经关闭了服务器和应用程序之间的jms连接。
注意：在服务器中禁用（停止）我的应用程序部署后，错误仅在日志中打印一次。
