JMS_使用ActiveMQ实现消息的发送和接收

一、说明

示例中使用activeMQ-all的jar包实现jms消息的发送和接收，发送端和接收端不依赖与服务器，如果想了解使用服务器配置的方式请参照之前的jsm和MDB的文章。

注意topic消息和queue消息的区别。

二、配置

1、ActiveMQ配置

activemq-web-console的配置不再重复。

2、Maven配置

<dependency><groupId>org.apache.activemq</groupId><artifactId>activemq-all</artifactId><version>5.5.0</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-nop</artifactId><version>1.6.2</version></dependency>

三、发送方和接收方的代码

1、发送方

public class AMQProducer {public static void main(String[] args) throws Exception {MessageProducer producer = null;Connection connection = null;ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");connection = factory.createConnection();ActiveMQSession session = (ActiveMQSession) connection.createSession(false, Session.AUTO_ACKNOWLEDGE);Queue queue = session.createQueue("myQueue2");producer = session.createProducer(queue);// Topic topic = session.createTopic("myTopic2");// producer = session.createProducer(topic);TextMessage textMessage = session.createTextMessage();textMessage.setText("Hello AMQ2");producer.send(textMessage);producer.close();connection.close();}}

2、接收方

public class AMQConsumer {public static void main(String[] args) throws Exception {ActiveMQConnectionFactory connFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");Connection conn = connFactory.createConnection();conn.start();Session session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);Queue queue = session.createQueue("myQueue2");MessageConsumer consumer = session.createConsumer(queue);// Topic topic = session.createTopic("myTopic2");// MessageConsumer consumer = session.createConsumer(topic);TextMessage message = (TextMessage) consumer.receive();String msg = message.getText();System.out.println(msg);consumer.close();conn.close();}}
