Spring Cloud Config Server - 用於刷新密鑰的空數組

Question

我有一個春天的雲配置服務器在這種回購而在這個客戶端回購以下是我的POM文件

配置服務器的 application.yml

server:
  port: 8081
spring:
  application:
    name: cloud-config-server
  cloud:
    config:
      server:
        monitor:
          github:
            enabled: true
          gitee:
            enabled: true
        git:
          password: ${PASSWORD}
          username: ${USERNAME}
          uri: https://github.com/Ali-Wassouf/springcloudconfigrepo
          search-paths: '{application}'

該服務器服務的配置倉庫具有以下結構

.
+-- serviceA
|   +-- application-dev.properties
|   +-- application-prod.properties
+-- serviceB
|   +-- application-dev.properties
|   +-- application-prod.properties

我為配置存儲庫配置了一個 webhook。 我還有一個在本地運行的 rabbitMQ 圖像。

當我將更改推送到配置存儲庫時，我會在控制台上看到這些行

o.s.c.c.monitor.PropertyPathEndpoint     : Refresh for: *:prod
s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@2c943d8f: startup date [Mon Nov 23 18:55:19 CET 2020]; root of context hierarchy

o.s.cloud.bus.event.RefreshListener      : Received remote refresh request. Keys refreshed []

Refreshed 鍵數組為空我嘗試更改為舊版本的 Spring Boot/Cloud 以及更新版本，但這不起作用。

我見過與我的案例類似的問題，但沒有一個有任何答案。

Answer 1

在您的application.yml您已經定義了spring.cloud.config.server.git.search-paths配置鍵。 但是，從 spring 官方文檔中查看此文檔，關鍵似乎應該是searchPaths （snakeCase，沒有破折號）。 因此，我認為您的application.yml應該如下所示：

server:
  port: 8081
spring:
  application:
    name: cloud-config-server
  cloud:
    config:
      server:
        monitor:
          github:
            enabled: true
          gitee:
            enabled: true
        git:
          password: ${PASSWORD}
          username: ${USERNAME}
          uri: https://github.com/Ali-Wassouf/springcloudconfigrepo
          searchPaths: '{application}'

Answer 2

問題出在客戶端，缺少 spring cloud 配置以及 spring cloud 的依賴管理將此依賴項添加到客戶端代碼

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>

並添加此依賴項管理

<dependencyManagement>
       <dependencies>
           <dependency>
               <groupId>org.springframework.cloud</groupId>
               <artifactId>spring-cloud-dependencies</artifactId>
               <version>${spring-cloud.version}</version>
               <type>pom</type>
               <scope>import</scope>
           </dependency>
       </dependencies>
</dependencyManagement>

解決了這個問題。
