访问/刷新执行器不工作时出现意外错误（类型=不允许方法，状态=405）错误

Question

我创建了一个 @RestController class 并尝试使用来自配置服务器的 /refresh 执行器值。 /刷新执行器不工作。我收到以下错误。 Spring 引导版本为 2.0.0-Release。我无法升级 spring 引导版本。

http://localhost:8888/secondservice/admin/refresh

    Whitelabel Error Page
    This application has no explicit mapping for /error, so you are seeing this as a fallback.

Answer 1

There was an unexpected error (type=Method Not Allowed, status=405). Request method 'GET' not supported

上述错误意味着 HTTP GET 在该特定端点上不受支持。

要从 spring 配置服务器刷新配置，您需要在 http://localhost:8888/secondservice/admin/refresh

上发出 HTTP POST 请求

以下来自Springguide

You can invoke the refresh Actuator endpoint by sending an empty HTTP POST to the client’s refresh endpoint

要发出 HTTP POST 请求，您可以使用任何 HTTP 客户端，例如 Postman or cURL。要使用 cURL，您可以运行在终端上执行以下命令

curl -X POST http://localhost:8888/secondservice/admin/refresh
