SpringBoot集成rabbitmq:java.net.ConnectException

SpringBoot集成rabbitmq錯誤:org.springframework.amqp.AmqpConnectException: java.net.ConnectException的解決辦法

秒殺項目集成了rabbitmq，啓動項目時，報錯，錯誤信息如下：

配置文件如下：

#rabbitmq
spring.rabbitmq.host=ip
spring.rabbitmq.port=5672
spring.rabbitmq.username=username
spring.rabbitmq.password=password
spring.rabbitmq.virtual-host=/  

注意：用戶使用的是guest,而guest只能默認只能連接本機IP(也就是127.0.0.1)，而192.168.220.128是虛擬機的ip，所以會報org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused: connect

解決方法：就是修改rabbitmq的配置文件rabbitmq.config 增加一行代碼

1、進入rabbitmq的安裝目錄（視個人情況而定）

2、編輯abbitmq.config配置文件

3、增加如下代碼:

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