Spring Cloud Config 自动刷新所有节点 架构改造

详细参考：《Sprin Cloud 与 Docker 微服务架构实战》p162-9.9.4节

要做的改动是：

1、在spring cloud config server 服务端加入 spring-cloud-starter-bus-amqp 包

</project>

　　

2、添加配置

  rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest

spring:
  application:
    name: thunisoft-microservice-configs
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/ultrastrong/spring-cloud-config
          clone-on-start: true # 启动时候就clone配置仓库
        default-application-name: thunisoft-microservice-foo
  rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest
server:
  port: 8979
# 默认关闭权限验证
management:
  security:
    enabled: false

　　不要忘记关闭服务器端的安全认证，否则无法访问到端点。

3、使用 /bus/refresh 端点刷新配置时，只要在 服务器端就行了，这样所有的端点就都能收到更新请求了。

http://localhost:8979/bus/refresh
