1.下载apache-activemq-5.14.5-bin.zip
2、运行ActiveMQ
解压缩apache-activemq-5.5.1-bin.zip,然后双击apache-activemq-5.5.1\bin\activemq.bat运行ActiveMQ程序。
启动ActiveMQ以后,登陆:http://localhost:8161/admin/,用户名:admin,密码:admin 创建一个Queue,命名为FirstQueue。
3、jar包准备
4、测试小程序开发
创建project:Receiver,并导入jar目录下需要用到的jar文件,项目结构如下图所示:
在另一个warkspace打开eclipse创建sender
Receiver.java
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.MessageConsumer;
import javax.jms.Session;
import javax.jms.TextMessage;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
public class Receiver {
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,"tcp://localhost: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) {
}
}
}
}
sender.java
import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
public class sender {
private static final int SEND_NUMBER = 5;
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,"tcp://localhost: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);
}
}
}
刚开始eclipse1中运行Receiver以后console介面没有任何信息,在eclipse2中运行Sender以后,eclipse2中的console显示如下信息
