spring cloud连接rabbitmq失败

遇到一个很操蛋的问题.

spring cloud简单集成 stream

启动, 

配置文件

spring:
  application:
    name: demox-service
    index: ${spring.application.name}
  rabbitmq:
    host: 192.168.0.100
    port: 5672
    username: username
    password: 111111
    virtual-host: /test-config

然后发现日志没有错误,但是mq页面就是没有连接

然后仔细看日志:

Failed to declare exchange,出现一堆的Failed.

进入他的源代码调试一下 AmqpConnectException

原来配置文件没有读取正确.坑死人了.

加入config依赖

		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-config</artifactId>
		</dependency>

然后就能正常读取配置,连接mq就成功了...
