package com.example.demo02.mq.util;

import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

import java.io.IOException;

public class ConnectionUtils {
    //为什么使用静态代码块初始化连接工厂？
    //因为连接工厂只需要初始化一次，所以使用静态代码块初始化
    private static ConnectionFactory connectionFactory;
    static {
        // 创建连接工厂
        connectionFactory = new ConnectionFactory();
        //mq服务主机地址
        connectionFactory.setHost("*********");
        //连接端口
        connectionFactory.setPort(40991);
        connectionFactory.setVirtualHost("/my240410");
        //设置用户名
        connectionFactory.setUsername("allen");

    public static Connection getConnection() {

            return null;

@SpringBootTest

    @Test

}
