SpringBoot配置多个RabbitMq

• YML

 rabbitmq:
    first:
      username: ${app.appkey}
      password: ${app.appkey}
      virtual-host: ${app.appid}
      addresses: x.x.x.x:5672,x.x.x.x:5672 #集群
    second:
      username: guest 
      password: guest
      virtual-host: /
      host: 127.0.0.1
      port: 5672
