ActionMQ 是开源的JMS实现,以下文章内容由小编根据大牛们的文献进行的总结测试
参考连接:http://www.cnblogs.com/xwdreamer/archive/2012/02/21/2360818.html
1.下载ActiveMQ
去官方网站下载:http://activemq.apache.org/
2.运行ActiveMQ
解压缩apache-activemq-5.5.1-bin.zip,然后双击apache-activemq-5.8.0\bin\activemq.bat运行ActiveMQ程序。
启动ActiveMQ以后,登陆:http://localhost:8161/admin/,创建一个Queue,命名为FirstQueue。如下图
目录结构如下:
运行在网页中,它会让你登录用户方可进入,默认的用户名和密码是admin,
3 . 测试
ActiveMQ默认使用的TCP连接端口是61616,通过查看该端口的信息可以测试ActiveMQ是否成功启动window环境运行 netstat -an|find "61616"
Class源代码中可以看到
4.创建Eclipse JAVA项目并运行
创建project:ActiveMQ-5.8,并导入apache-activemq-5.8.0\lib目录下需要用到的jar文件,项目结构如下图所示:
若找不到相应的包,使用以下连接下载也行 http://repo1.maven.org/maven2/org/apache/activemq/activemq-rar/
3.1.Sender.java
package cn.jms; 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); } } }
3.2.Receiver.java
package cn.jms; 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,这里设定为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) { } } } }
4.注意事项
先启动apache-activemq-5.8.0\bin\activemq.bat运行ActiveMQ程序。在运行main方法,否则回报连接失败的错误,如下
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details. javax.jms.JMSException: Could not connect to broker URL: tcp://localhost:61616.

5.测试过程
1、先运行Sender,输出以下信息,若先运行Receiver则无输出
发送消息:ActiveMq 发送的消息1
发送消息:ActiveMq 发送的消息2
发送消息:ActiveMq 发送的消息3
发送消息:ActiveMq 发送的消息4
发送消息:ActiveMq 发送的消息5
2、运行Receiver
收到消息ActiveMq 发送的消息1
收到消息ActiveMq 发送的消息2
收到消息ActiveMq 发送的消息3
收到消息ActiveMq 发送的消息4
收到消息ActiveMq 发送的消息5
