rabbitmq 学习-3-初试1

本例是一个简单的异步发送消息实例
1，发送端
@Test(groups = { "sunjun" })
public class RabbitmqTest {
    private static Connection connection;
    static {
        ConnectionParameters params = new ConnectionParameters();
        ConnectionFactory factory = new ConnectionFactory(params);
        try {
            connection = factory.newConnection("192.168.18.21",
                    AMQP.PROTOCOL.PORT);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public void testSend() {
        try {
            Channel channel = connection.createChannel();
            System.out.println(channel.toString());
            Assert.assertNotNull(channel);
            byte[] messageBodyBytes = "hello world".getBytes();
            channel.basicPublish("exchangeName", "routingKey",
                    MessageProperties.PERSISTENT_TEXT_PLAIN, messageBodyBytes);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
2，接收端
@Test(groups = { "sunjun" })
public class RabbitmqTestB {
    private static Connection connection;
    static {
        ConnectionParameters params = new ConnectionParameters();
        ConnectionFactory factory = new ConnectionFactory(params);
        try {
            connection = factory.newConnection("localhost", AMQP.PROTOCOL.PORT);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public void testReceive() {
        try {
            Channel channel = connection.createChannel();
            System.out.println(channel.toString());
            Assert.assertNotNull(channel);
            channel.exchangeDeclare("exchangeName", "direct");
            channel.queueDeclare("queueName");
            channel.queueBind("queueName", "exchangeName", "routingKey");
            boolean noAck = false;
            GetResponse response = channel.basicGet("queueName", true);
            if (response == null) {
                System.out.println("No message retrieved.");
            } else {
                AMQP.BasicProperties props = response.getProps();
                byte[] body = response.getBody();
                System.out.println(new String(body));
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
先执行下发送端，再执行下接收端，输出：hello world
ok
