ActiveMQ 初学

直接上代码：

  发送：

 public static void main(String[] args) {  
        // ConnectionFactory ：连接工厂，JMS 用它创建连接  
        ConnectionFactory connectionFactory; // Connection ：JMS 客户端到JMS  
        // Provider 的连接  
        Connection connection = null; // Session： 一个发送或接收消息的线程  
        Session session; // Destination ：消息的目的地;消息发送给谁.  
        Destination destination; // MessageProducer：消息发送者  
        MessageProducer producer; // TextMessage message;  
        // 构造ConnectionFactory实例对象，此处采用ActiveMq的实现jar  
        connectionFactory = new ActiveMQConnectionFactory(  
                ActiveMQConnection.DEFAULT_USER,  
                ActiveMQConnection.DEFAULT_PASSWORD, "failover:(tcp://localhost:61616,tcp://10.1.1.123:61616)");  
        try { // 构造从工厂得到连接对象  
            connection = connectionFactory.createConnection();  
            // 启动  
            connection.start();  
            // 获取操作连接  
            session = connection.createSession(Boolean.TRUE,  Session.AUTO_ACKNOWLEDGE);  
            // 获取session注意参数值xingbo.xu-queue是一个服务器的queue，须在在ActiveMq的console配置  
            destination = session.createQueue("FirstQueue");  
            // 得到消息生成者【发送者】  
            producer = session.createProducer(destination);  
            // 设置不持久化，此处学习，实际根据项目决定  
            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);  
            // 构造消息，此处写死，项目就是参数，或者方法获取  
            sendMessage(session, producer);  
            session.commit();  
        } catch (Exception e) {  
            e.printStackTrace();  
        } finally {  
            try {  
                if (null != connection)  
                    connection.close();  
            } catch (Throwable ignore) {  
            }  
        }  
    }  
  
    public static void sendMessage(Session session, MessageProducer producer)  
            throws Exception {  
        for (int i = 1; i <= SEND_NUMBER; i++) {  
            TextMessage message = session.createTextMessage("ActiveMq 发送的消息"  
                    + i);  
            // 发送消息到目的地方  
            System.out.println("发送消息：" + "ActiveMq 发送的消息" + i);  
            producer.send(message);  
        }  
    }  

  接收：

 public static void main(String[] args) {  
        // ConnectionFactory ：连接工厂，JMS 用它创建连接  
        ConnectionFactory connectionFactory;  
        // Connection ：JMS 客户端到JMS Provider 的连接  
        Connection connection = null;  
        // Session： 一个发送或接收消息的线程  
        Session session;  
        // Destination ：消息的目的地;消息发送给谁.  
        Destination destination;  
        // 消费者，消息接收者  
        MessageConsumer consumer;  
        connectionFactory = new ActiveMQConnectionFactory(  
                ActiveMQConnection.DEFAULT_USER,  
                ActiveMQConnection.DEFAULT_PASSWORD, "failover:(tcp://localhost:61616,tcp://10.1.1.123:61616)");  
        try {  
            // 构造从工厂得到连接对象  
            connection = connectionFactory.createConnection();  
            // 启动  
            connection.start();  
            // 获取操作连接  
            session = connection.createSession(Boolean.FALSE,  Session.AUTO_ACKNOWLEDGE);  
            // 获取session注意参数值xingbo.xu-queue是一个服务器的queue，须在在ActiveMq的console配置  
            destination = session.createQueue("FirstQueue");  
            consumer = session.createConsumer(destination);  
            while (true) {  
                // 设置接收者接收消息的时间，为了便于测试，这里谁定为100s  
            	
                TextMessage message = (TextMessage) consumer.receive(100000);  
                if (null != message) {  
                    System.out.println("收到消息" + message.getText());  
                } else {  
                    break;  
                }  
            }  
        } catch (Exception e) {  
            e.printStackTrace();  
        } finally {  
            try {  
                if (null != connection)  
                    connection.close();  
            } catch (Throwable ignore) {  
            }  
        }  
    }  

 

基于Spring的ActiveMQ:

  XML文件：

<bean id="topicListenConnectionFactory" class="org.apache.activemq.spring.ActiveMQConnectionFactory">
		<property name="brokerURL" value="tcp://127.0.0.1:61616" />
		<property name="clientID" value="clientId_007" />
	</bean>


<bean id="deviceListener" class="net.coc.activemq.listener.DeviceMessageListener">
		<property name="deviceAdapter" ref="deviceAdapter"></property>
	</bean>

<bean id="deviceTopic" class="org.apache.activemq.command.ActiveMQTopic">
		<constructor-arg value="Assets.Device.Topic" />
	</bean>

<bean
		class="org.springframework.jms.listener.DefaultMessageListenerContainer">
		<property name="connectionFactory" ref="topicListenConnectionFactory" />
		<property name="pubSubDomain" value="true" />
		<property name="receiveTimeout" value="10000" />
		<property name="destination" ref="deviceTopic" />
		<property name="subscriptionDurable" value="true" />
		<property name="clientId" value="deviceListenerclientId_007" />
		<property name="durableSubscriptionName" value="deviceListenerclientId_007" />
		<property name="messageListener" ref="deviceListener" />
	</bean>

 

Java：

public class DeviceMessageListener implements MessageListener {

	private DeviceAdapter deviceAdapter;

	public DeviceAdapter getDeviceAdapter() {
		return deviceAdapter;
	}

	public void setDeviceAdapter(DeviceAdapter deviceAdapter) {
		this.deviceAdapter = deviceAdapter;
	}

	@Override
	public void onMessage(Message message) {
		TextMessage textMsg = (TextMessage) message;
		try {
			JSONObject msg = JSONObject.fromObject(textMsg.getText());
			deviceAdapter.execute(msg);
			deviceAdapter.finish();
		} catch (JMSException e) {
			e.printStackTrace();
			throw new RuntimeException(e);
		} catch (Exception e) {
			e.printStackTrace();
			throw new RuntimeException(e);
		}
	}
}

 

 

deviceAdapter 是具体解析消息的处理类，这个需要根据各自的需求自己定制；
