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

</dependencyManagement> <build>

<plugin>

</plugins>
</build> </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
