public class RabbitMQConnection {
    public static Connection getConnection() throws Exception{
        //1.创建connectionFactory
        ConnectionFactory connectionFactory = new ConnectionFactory();
        //2.配置Host
        connectionFactory.setHost("127.0.0.1");
        //3.设置Port
        connectionFactory.setPort(5672);
        //4.设置账户和密码
        connectionFactory.setUsername("guest");
        connectionFactory.setPassword("guest");
        //5.设置VirtualHost
        connectionFactory.setVirtualHost("0517");
        return connectionFactory.newConnection();
    }
}
