activeMq的点对点发送

1. 建立连接工厂

ConnectionFactory factory = new ActiveMQConnectionFactory("system","manager","tcp://localhost:61616"); 参数1：用户名，默认：ActiveMQConnection.DEFAULT_USER=null;可以根据mq的配置文件自己设置 参数2：密码，默认：ActiveMQConnection.DEFAULT_PASSWORD=null;可以根据mq的配置文件自己设置 参数3：url，默认：ActiveMQConnection.DEFAULT_BROKER_URL=failover://tcp://localhost:61616; url有几种：

1. TCP：

			MQ默认使用的协议，开放性、高效性、可靠性是其主要特点，这个协议可满足一般应用的大部分需求，因此在项目中还是比较常用的。
			<transportConnector name="nio" uri="nio:localhost:61618" />  

2. NIO：

			网络消息的传播效率非常的高。因此，当系统存在高用户量、高并发或网络堵塞时，可考虑用此协议。

3. SSL：

			安全套接层协议
			在MQ目录/conf/activemq.xml文件中修改以下配置Xml代码：
				<sslContext>   
					<sslContext keyStore="file:${activemq.base}/conf/broker.ks" keyStorePassword="password"/>   
				</sslContext>  
				<transportConnectors>  
					<transportConnector name="ssl" uri="ssl://localhost:61617"/>  
				</transportConnectors>  

2. 建立连接

Connection conn = factory.createConnection();

3. 获取session

Session session = conn.createSession(true, Session.AUTO_ACKNOWLEDGE); 参数1：是否自动提交 参数2：Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, Session.DUPS_OK_ACKNOWLEDGE

4. 建立Destination

Destination destination = session.createQueue("queue");

5. 建立MessageProducer

MessageProducer producer = session.createProducer(destination);

6. 产生消息并发送：

ObjectMessage om = session.createObjectMessage(d); producer.send(om);

7. 建立消费者

MessageConsumer consumer = session2.createConsumer(destination2);

8. 注册监听器

consumer.setMessageListener(new MyListener());
