(S3后端不工作)Spring配置服务器:无法从AWS S3获取配置文件内容

Question

我使用S3作为Spring Config服务器的后端。我在我的bucket中上传了3个文件。

1. application-local.properties
2. 应用程序专用属性
3. application-qa.properties

然后，我将尝试达到文档中提到的REST API端点。

网址：http://localhost:4000/application/qa

9秒后，我得到了200的回复，下面是身体。

"name": "application",
"profiles": [
"qa"
],
"label": null,
"version": null,
"state": null,
"propertySources": []
} 

从技术上讲，我应该在propertySources中获取数据，但我什么都没得到。

我不知道如何解决这个问题。

Answer 1

有几件事可能会有所帮助。如果您使用的是Spring Boot>=2.4，属性spring.cloud.config.server.bootstrap=true需要作为命令行参数或通过此处的maven启动器提供。该属性必须在"；引导程序"；读取CCD_ 3之前的相位。

它可能与以下内容有关：

• IAM访问所选存储桶
• 凭据-在使用配置服务器时，我只使用了针对AWS S3的提供程序链进行身份验证。从源代码来看，提供程序链似乎是创建S3客户端的唯一方法。遗憾的是，您不能配置自己的AmazonS3bean

您得到的响应表明应用程序可以与S3对话，但无法找到属性。如果Spring Config Server无法与S3通信，则在命中/actuator/health时，它将报告DOWN。你的应用程序在执行器中显示健康吗？
