public class Producer {
    
    

    private final static  String QUEUE_NAME="hello";
    public static Connection getConnetion (String[] args) throws Exception{
    
    
        /**
         * 获取连接
         */
        com.rabbitmq.client.Connection connection = ConnectionUtil.getConnection("172.16.16.115", 5672, "/", "guest", "guest");

        return null;
    }
}

import com.rabbitmq.client.Connection;
