Provider 提供工具管理队列的创建、删除。JMS PTP 模型定义了客户端如何向队列发送消息，从队列接收消息，浏览队列中的消息。 <pre name="code" class="java"> package activemq.test.p2p.consumer; import org.springframework.jms.core.JmsTemplate; import

消息订阅分为非持久订阅(non-durable subscription)和持久订阅(durable subscrip-tion)，非持久订阅只有当客户端处于激活状态，也就是和JMS Provider 保持连接状态才能收到发送到某个主题的消息，而当客户端处于离线状态，这个时间段发到主题的消息将会丢失，永远不会收到。持久订阅时，客户端向JMS 注册一个识别自己身份的ID，当这个客户端处于离线时，JMS Provider 会为这个ID 保存所有发送到主题的消息，当客户再次连接到JMS Provider时，会根据自己的ID 得到所有当自己处于离线时发送到主题的消息。 <pre name="code" class="java"> package activemq.test.topic; import javax.jms.Connection;
