Spring cloud config 自动即时刷新所有值

Question

all：在我的 env 中，所有配置都存储在 localfile 中？所以我的服务配置文件存储在 classpath:configs/ 中。

因此，当 classpath:configs/ 中的文件发生更改时，需要即时刷新以提供最新属性，我需要自动刷新所有值，我该如何满足此需求？

Here is my configuration of config server:

应用程序.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

引导程序.yml

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

我在模块资源目录中有一个configuration.yml ：

配置（-默认与否）.yml

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

Here is my configuration of config client:

引导程序.yml

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

应用程序.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;
  }
}

它可以http://localhost:7002/prop2/在浏览器中访问时打印“world” ，但是当配置服务器resources/configurations.yml发生变化时，curl -X POST http://localhost:7002/refresh什么都没有改变，只返回 [](It should return ["prop2"]) 和访问相同的结果http://localhost:7002/prop2/。

发布/刷新时登录控制台：

配置服务器：

我认为这是从类路径加载配置的限制。由于您无法在应用程序运行时动态更改类路径，因此我们无法重新加载更改。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外部的搜索路径位置（以及高度可用的位置）。当您指定搜索路径位置时，您可以更新配置，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
