条件评估报告（conditions）

QWen Max 中英对照 Conditions Evaluation Report (conditions) Conditions Evaluation Report (conditions)

conditions 端点提供了有关配置类和自动配置类上条件评估的信息。

获取报告

要获取报告，请向 /actuator/conditions 发起 GET 请求，如下列基于 curl 的示例所示：

$ curl 'http://localhost:8080/actuator/conditions' -i -X GET

得到的响应类似于以下内容：

HTTP/1.1 200 OK
Content-Type: application/vnd.spring-boot.actuator.v3+json
Content-Length: 3227
