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.
首先我们要下载ActiveMQ，下载地址：
http://www.apache.org/dyn/closer.cgi?path=/activemq/apache-activemq/5.8.0/apache-activemq-5.8.0-bin.zip
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。
一、显示发送者的对象
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.MessageProducer;
import javax.jms.ObjectMessage;
import javax.jms.Session; import org.apache.activemq.ActiveMQConnectionFactory; public class Sender { public static void main(String[] args) throws Exception {
aa();
}
public static void aa() throws Exception{
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);
}
System.out.println("ok...");
session.commit();
session.close();
connection.close();
}
}
二、接受者对象
import java.util.concurrent.TimeUnit; import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;
import javax.jms.Session; import org.apache.activemq.ActiveMQConnectionFactory; public class Receiver { public static void aa() throws Exception{
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.getName());
} catch (JMSException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
session.commit();
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} });
TimeUnit.MINUTES.sleep(1); session.close();
connection.close();
} public static void main(String[] args) throws Exception{
aa();
}
}
import java.io.Serializable;
public class User implements Serializable {
private int id;
private String name;
private String pwd;
public User(int id,String name,String pwd){
this.id=id;
this.name=name;
this.pwd=pwd;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}
先运行发送者，然后运行接收者即可。。。。
