Apache ActiveMQ消息中间件的基本使用
Apache ActiveMQ是Apache软件基金会所研发的开放源码消息中间件;由于ActiveMQ是一个纯Java程式,因此只需要操作系统支援Java虚拟机,ActiveMQ便可执行。
支持Java消息服务 (JMS) 1.1 版本
Spring Framework
集群 (Clustering)
支持的编程语言包括:C、C++、C#、Delphi、Erlang、Adobe Flash、Haskell、Java、JavaScript、Perl、PHP、Pike、Python和Ruby [1]
协议支持包括:OpenWire、REST、STOMP、WS-Notification、XMPP以及AMQP
好,我们先写个demo来试试 ActiveMQ的效果.
解压后,在x:/apache-activemq-5.8.0-bin/bin 目录下执行 activemq.bat即可启动 ActiveMQ,
由于ActiveMQ内置了Jetty web服务器,当ActiveMQ启动成功后,可以通过:http://localhost:8161/admin/访问ActiveMQ的控制台,默认的用户名和密码是:admin。
至此ActiveMQ 服务已经启动了,接下来我们先将x:/apache-activemq-5.8.0-bin/activemq-all-5.8.0.jar拷贝到你的classpath目录下,利用Java写个demo来尝试一下这个消息中间件。
JmsSender:
[java]
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://127.0.0.1:61616");
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("Test.foo");
MessageProducer producer = session.createProducer(destination);
producer.setDeliveryMode(DeliveryMode.PERSISTENT);
for(int i=0; i<100; i++) {
int id = i+1;
ObjectMessage message = session.createObjectMessage();
message.setObject(new User(id, "张三"+id, "123456"));
producer.send(message);
}
session.commit();
session.close();
connection.close();
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://127.0.0.1:61616");
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("Test.foo");
MessageProducer producer = session.createProducer(destination);
producer.setDeliveryMode(DeliveryMode.PERSISTENT);
for(int i=0; i<100; i++) {
int id = i+1;
ObjectMessage message = session.createObjectMessage();
message.setObject(new User(id, "张三"+id, "123456"));
producer.send(message);
}
session.commit();
session.close();
connection.close();
JmsReceiver:
[java]
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://127.0.0.1:61616");
Connection connection = connectionFactory.createConnection();
connection.start();
final Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("Test.foo");
MessageConsumer consumer = session.createConsumer(destination);
//listener 方式
consumer.setMessageListener(new MessageListener() {
public void onMessage(Message msg) {
ObjectMessage message = (ObjectMessage) msg;
//TODO something....
try {
User user = (User) message.getObject();
System.out.println("收到消息:"+user);
} catch (JMSException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
session.commit();
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
