Spring Cloud学习笔记【十】配置中心（消息驱动刷新配置）

上一篇中讲到，如果需要客户端获取到最新的配置信息需要执行refresh，我们可以利用 Webhook 的机制每次提交代码发送请求来刷新客户端，当客户端越来越多的时候，需要每个客户端都执行一遍，这种方案就不太适合了。使用 Spring Cloud Bus 可以完美解决这一问题。

服务端

新建一个spring boot项目，命名 service-config-server-bus

配置文件

    password: 123456

bootstrap.yml

spring:
  cloud:
    config:
      name: config-server # 对应 {application} 部分
      profile: dev # 对应 {profile} 部分
      label: master # 对应 {label} 部分，即 Git 的分支。如果配置中心使用的是本地存储，则该参数无用
      discovery:
        enabled: true
        service-id: service-config-server-bus #springcloud config的服务名
eureka:
  client:
    serviceUrl:
      defaultZone: http://admin:123456@localhost:8761/eureka/

控制层Controller

 1 package com.carry.springcloud;
 2 
 3 import org.springframework.beans.factory.annotation.Value;
 4 import org.springframework.cloud.context.config.annotation.RefreshScope;
 5 import org.springframework.web.bind.annotation.GetMapping;
 6 import org.springframework.web.bind.annotation.RestController;
 7 
 8 import reactor.core.publisher.Mono;
 9 
10 @RestController
11 @RefreshScope
12 public class ClientController {
13 
14     @Value("${info.profile}")
15     private String profile;
16 
17     @GetMapping("/info")
18     public Mono<String> hello() {
19         return Mono.justOrEmpty(profile);
20     }
21 }

@RefreshScope必须加，否则客户端会受到服务端的更新消息，但是更新不了，因为不知道更新哪里的，至于启动主类，用默认生成的不用改。

测试

分别启动 eureka-server、service-config-server-bus 和两个 service-config-client-bus

启动后，RabbitMQ 中会自动创建一个 topic 类型的 Exchange 和两个以springCloudBus.anonymous.开头的匿名 Queue

我们用Postman发生请求 http://localhost:9400/info 和 http://localhost:9401/info 返回内容的都是dev。

将 Git 中的配置信息由dev改为dev bus，并执行POST http://localhost:9300/actuator/bus-refresh 之后，再请求 http://localhost:9400/info 和 http://localhost:9401/info ，返回dev bus 说明成功了。
