非spring集成方式

消息创建者

public class Producer {
private static final String TASK_QUEUE_NAME = "fenfatest.task_queue";

public static void main(String[] args)
throws IOException, TimeoutException, java.util.concurrent.TimeoutException, InterruptedException {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("192.168.231.209");
factory.setPort(5672);
factory.setUsername("test");
factory.setPassword("test");
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();
channel.queueDeclare(TASK_QUEUE_NAME, true, false, false, null);
// 分发信息
for (int i = 0; i < 10; i++) {
String message = "Hello RabbitMQ" + i;
channel.basicPublish("", TASK_QUEUE_NAME, MessageProperties.PERSISTENT_TEXT_PLAIN, message.getBytes());
System.out.println("NewTask send '" + message + "'");
}
channel.close();
connection.close();
}
}

消息消费者

public class Work2 {

private static final String TASK_QUEUE_NAME = "fenfatest.task_queue";

public static void main(String[] args) throws IOException, TimeoutException {
ConnectionFactory factory = new ConnectionFactory();
factory.setHost("192.168.231.209");
factory.setPort(5672);
factory.setUsername("test");
factory.setPassword("test");
Connection connection = factory.newConnection();
Channel channel = connection.createChannel();

channel.queueDeclare(TASK_QUEUE_NAME, true, false, false, null);
System.out.println("Worker2 Waiting for messages");

// 每次从队列获取的数量
channel.basicQos(1);
final Consumer consumer = new DefaultConsumer(channel) {
@Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties,
byte[] body) throws IOException {
String message = new String(body, "UTF-8");
System.out.println("Worker2 Received '" + message + "'");
}
};
boolean autoAck = true;
// 消息消费完成确认
channel.basicConsume(TASK_QUEUE_NAME, autoAck, consumer);

}
}
