Question

所有：在我的环境中，所有配置都存储在localfile中，因此我的服务配置文件存储在classpath中：configs /.

因此，当classpath中的文件：配置/更改，需要动态刷新以提供最新属性时，我需要自动刷新所有值，我怎样才能满足这种需求？

Here is my configuration of config server:

application.yml

server:
  port: 8003
endpoints:
  restart:
    enabled: true
  refresh:
    enabled: true
spring:
  cloud:
    config:
      server:
        native:
          searchLocations: classpath:/
 etcd:
   conn:
     etcdPassword: 134
     etcdUrls:
     - http://localhost:2379
     etcdUsername: root
     enabled: true
   etcdServicePrefix: /congiguration/project1/
   enabled: true
   timeout: 1

bootstrap.yml

spring:
  application:
    name: configurations
  profiles:
     active: native

我有一个configurations.yml位于moudule 资源目录：

配置（-default与否）.yml

prop1: Hello
prop2: world
etcd:
   conn:
     etcdPassword: 134

Here is my configuration of config client:

bootstrap.yml

spring:
  application:
    name: configurations
  cloud:
    config:
      uri: http://localhost:8003/

application.yml

server:
  port: 7002
    management:
  security:
    enabled: false

入口点

@RefreshScope
@RestController
class TestController {
@Value("${prop2}")
private String prop2;
@RequestMapping("/prop2")
public String from() {
    return this.prop2;
  }
}

在浏览器中访问http://localhost:7002/prop2/时可以打印“世界”，但是当配置服务器 resources/configurations.yml 发生更改时，curl -X POST http://localhost:7002/refresh没有任何更改，只返回[] （它应该返回[“prop2”]）并通过访问http://localhost:7002/prop2/获得相同的结果。

发布/刷新时

登录控制台：

我认为这是从类路径加载配置的限制。由于在应用程序运行时无法动态更改类路径，因此无法重新加载更改。推荐的方法（如文档中所指出的）是为生产用例指定应用程序之外的搜索路径位置（以及高度可用的位置）。指定搜索路径位置时，可以更新配置，配置服务器将获取这些更改。 https://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_file_system_backend

Spring cloud config会自动刷新所有值
