搭建高可用rabbitmq集群及spring boot实现集群配置

# 具体参看了配置的源码
# org.springframework.boot.autoconfigure.amqp.RabbitProperties
# RabbitMQ单机
spring:
  rabbitmq:
    host: localhost
    port: 5672
    username: your_username
    password: your_password
# RabbitMQ单机，只使用addresses
spring:
  rabbitmq:
    addresses:ip1:port1
    username: your_username
    password: your_password
# RabbitMQ集群，addresses一定要逗号分隔
spring:
  rabbitmq:
    addresses:ip1:port1,ip2:port2,ip3:port3
    username: your_username
    password: your_password
