import java.io.IOException;
import java.util.concurrent.TimeoutException;

public class Amqp {

    public  static Connection getConnection() throws IOException, TimeoutException {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("127.0.0.1");
        factory.setPort(5672);
        factory.setVirtualHost("/test");
        factory.setUsername("mm");
        factory.setPassword("123");
        Connection connection = factory.newConnection();
        return connection ;
    }
}

public class Send {

    private final static String QUEUE_NAME ="hello";
    public static void main(String[] args) throws IOException, TimeoutException {
            Connection connection = Amqp.getConnection();
            Channel channel = connection.createChannel();
