配置文件：

spring.rabbitmq.host=192.168.220.128
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest 
#spring.rabbitmq.port=5672
#spring.rabbitmq.virtual-host=

注意：用户使用的是guest,而guest只能默认只能连接本机IP(也就是127.0.0.1)，而192.168.220.128是虚拟机的ip，所以会报org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused: connect

解决方法：就是修改rabbitmq的配置文件rabbitmq.config 增加一行代码

1、进入rabbitmq的安装目录（视个人情况而定）

2、编辑abbitmq.config配置文件

3、增加如下代码

[{rabbit,[{loopback_users,[]}]}]
