ActiveMq的安装及使用

ActiveMq的安装

1. 解压缩ActiveMq的压缩包
2. 启动ActiveMq 在解压目录下bin中使用 activemq start

java操作ActiveMq

消息发布者的使用

    ConnectionFactory connectionFactory=new ActiveMQConnectionFactory("");
    Connection connection=connectionFactory.createConnection();
    connection.start();
    Session session=connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
    Queue queue=session.createQueue("");
    MessageProducer  producer=session.createProducer(queue);
    TextMessage textMessage=session.createTextMessage();
    textMessage.setText("");
    producer.send(textMessage);
    producer.close();
    session.close();
    connection.close();

消息接受者

    ConnectionFactory connectionFactory=new ActiveMQConnectionFactory("");
    Connection connection=connectionFactory.createConnection();
    connection.start();
    Session session=connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
    Queue queue=session.createQueue("");
    MessageConsumer consumer=session.createConsumer(queue);
    consumer.setMessageListener(new MessageListener() {

        @Override
        public void onMessage(Message message) {
            TextMessage textMessage=(TextMessage) message;
            try {
                textMessage.getText();
            } catch (JMSException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    }); 
    consumer.close();
    session.close();
    connection.close();

ActiveMq与Spring的整合

消息生产者

1. 先配置jms的connectionFactory
2. 然后配置singleConnectionFactory
3. 配置queue或者topic

4. 配置JmsTemplate

   <!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
   <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
       <property name="brokerURL" value="tcp://192.168.25.168:61616" />
   </bean>
   <!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
   <bean id="connectionFactory"
       class="org.springframework.jms.connection.SingleConnectionFactory">
       <!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
       <property name="targetConnectionFactory" ref="targetConnectionFactory" />
   </bean>
   <!-- 配置生产者 -->
   <!-- Spring提供的JMS工具类，它可以进行消息发送、接收等 -->
   <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
       <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
       <property name="connectionFactory" ref="connectionFactory" />
   </bean>
   <!--这个是队列目的地，点对点的 -->
   <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
       <constructor-arg>
       <value>spring-queue</value>
       </constructor-arg>
   </bean>
