Java 无法从Spring云配置服务器获取值到我的配置客户端（限制服务）

经过几天的互联网搜索和多次尝试（没有任何结果），我在这里写作

我有一个Project-spring云配置服务器，它有以下文件（可以从中访问完整的项目）

• SpringCloudConfigServerApplication.java
• application.properties（在文件夹-资源下）
• 链接源文件夹-git config repo，它限制了服务的属性文件
• pom.xml

和客户端配置项目-限制具有以下文件的服务（可从访问完整项目）

• LimitsServiceApplication.java
• LimitConfiguration.java
• Configuration.java
• LimitsConfiguration Controller.java
• bootstrap.properties（在文件夹-资源下）
• pom.xml

此外——

Project-SpringCloudConfigServer工作正常，具有以下输出

// http://localhost:8888/limits-service/default

{
  "name": "limits-service",
  "profiles": [
    "default"
  ],
  "label": null,
  "version": "8dd340030a5c82a11327bf0d2e55ae3b6434240b",
  "state": null,
  "propertySources": [
    {
      "name": "file:///D:/Learn-Java/springboot-workspace/git-config-repo//limits-service.properties",
      "source": {
        "limits-service.minimum": "11",
        "limits-service.maximum": "99"
      }
    }
  ]
}

但是当运行Project-limits服务时，我有以下输出。无法从spring云配置服务器获取数据

// http://localhost:8080/limits

{
  "minimum": null,
  "maximum": null
}

以下是项目方面的文件

SpringCloud2020.0不再默认使用引导。您需要启用引导或在application.properties中使用spring.config.import。稍后我会给出答案。Github链接足以让我反思并添加必要的内容。非常感谢您@Spencergib。根据2020.0发行说明，在配置客户端的pom.xml中添加SpringCloudStarter引导程序对我来说是可行的。对于其他人，将下面的依赖项jar放在pom.xml

org.springframework.cloud-spring-cloud-starter-bootstrap

@spencergib-这对我仍然不起作用。问题是-
