Question

我想计算队列中的消息。

InitialContext ctx = initQueue();
connFactory = (QueueConnectionFactory) ctx.lookup(CF_NAME);
queueConnection = connFactory.createQueueConnection();
queueConnection.start();
queueSession =
                queueConnection.createQueueSession(false, 
QueueSession.AUTO_ACKNOWLEDGE);
        queue = (Queue) ctx.lookup(queueName);

QueueBrowser queueBrowser = queueSession.createBrowser(queue);

但是在这里它停止了-------> QueueBrowser queueBrowser = queueSession.createBrowser（queue）

错误消息是：活动会话计数：1：org.wso2.andes.AMQDisconnectedException：不允许服务器关闭连接和重新连接。 javax.jms.JMSException：注册使用者时出错：org.wso2.andes.AMQException：由于类javax.jms.JMSException而唤醒在org.wso2.andes.client.AMQSession $ 6.execute（AMQSession.java:2143）在org.wso2.andes.client.AMQSession $ 6.execute（AMQSession.java:2086）在org.wso2.andes.client.AMQConnectionDelegate_8_0.executeRetrySupport（AMQConnectionDelegate_8_0.java:323）在org.wso2.andes.client.AMQConnection $ 3.run（AMQConnection.java:655）在java.security.AccessController.doPrivileged（本机方法）在org.wso2.andes.client.AMQConnection.executeRetrySupport（AMQConnection.java:652）在org.wso2.andes.client.failover.FailoverRetrySupport.execute（FailoverRetrySupport.java:102）在org.wso2.andes.client.AMQSession.createConsumerImpl（AMQSession.java:2084）在org.wso2.andes.client.AMQSession.createBrowserConsumer（AMQSession.java:1039）在org.wso2.andes.client.AMQQueueBrowser。（AMQQueueBrowser.java:51）在org.wso2.andes.client.AMQSession.createBrowser（AMQSession.java:1031）在org.wso2.andes.client.AMQSession.createBrowser（AMQSession.java:1018）在org.wso2.andes.client.AMQQueueSessionAdaptor.createBrowser（AMQQueueSessionAdaptor.java:87）在com.test.vediamo.ConnectionTest.doGet（ConnectionTest.java:96）在javax.servlet.http.HttpServlet.service（HttpServlet.java:622）在javax.servlet.http.HttpServlet.service（HttpServlet.java:729）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:292）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:207）在org.apache.tomcat.websocket.server.WsFilter.doFilter（WsFilter.java:52）在org.apache.catalina.core.ApplicationFilterChain.internalDoFilter（ApplicationFilterChain.java:240）在org.apache.catalina.core.ApplicationFilterChain.doFilter（ApplicationFilterChain.java:207）在org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:212）在org.apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:94）在org.apache.catalina.authenticator.AuthenticatorBase.invoke（AuthenticatorBase.java:504）在org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:141）

Answer 1

请先创建一个队列，然后按如下所示创建浏览器？

QueueBrowser浏览器= queueSession.createBrowser（queueSession.createQueue（“ test-queue”））;

JMS：不允许服务器关闭连接和重新连接
