创建连接的工具类:
//没有做成单例的 VirtualHost 需要复用 public class MQConnectionUtils { //创建新的连接 public static Connection newConnection() throws IOException, TimeoutException { //创建连接工厂 ConnectionFactory factory= new ConnectionFactory(); //链接地址 factory.setHost("192.168.91.6"); //用户名称 factory.setUsername("admin"); //用户密码 factory.setPassword("admin"); //amqp端口号 factory.setPort(5672); //连接virtualhost factory.setVirtualHost("/admin_toov5"); Connection connection = factory.newConnection(); return connection; } }
Producer类:
public class Producer { //队列名称 private static final String UEUE_NAME = "test_queue"; public static void main(String[] args) throws IOException, TimeoutException { //创建新的连接 Connection connection = MQConnectionUtils.newConnection(); //创建Channel Channel channel = connection.createChannel(); //创建队列 channel.queueDeclare(UEUE_NAME, false, false, false, null); //创建message String msg = "toov5_message"; System.out.println("生产者投递消息"+msg); //生产者发送消息 channel.basicPublish("",UEUE_NAME, null, msg.getBytes()); //关闭通道和连接 channel.close(); connection.close(); } }
运行结果,看下这个队列:
模拟Get message:
Consumer跟 Producer基本类似:
public class Consumer { //队列名称 private static final String QUEUE_NAME = "test_queue"; public static void main(String[] args) throws IOException, TimeoutException { System.out.println("消费者启动.........."); //创建新的连接 Connection connection = MQConnectionUtils.newConnection(); //创建Channel Channel channel = connection.createChannel(); // 消费者关联队列 channel.queueDeclare(QUEUE_NAME, false, false, false, null); DefaultConsumer defaultConsumerr = new DefaultConsumer(channel) { //监听获取消息 @Override public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties, byte[] body) throws IOException { String msg =new String(body,"UTF-8"); System.out.println("消费者获取生产者消息:"+msg); } }; //牵手模式设置 默认自动应答模式 true:自动应答模式 channel.basicConsume(QUEUE_NAME, true, defaultConsumerr); // //关闭通道和连接 // channel.close(); // connection.close(); } }
运行后的结果:
