Conditions Evaluation Report (`conditions`)

The conditions endpoint provides information about the evaluation of conditions on configuration and auto-configuration classes.spring-doc.cn

Retrieving the Report

To retrieve the report, make a GET request to /actuator/conditions, as shown in the following curl-based example:spring-doc.cn

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

The resulting response is similar to the following:spring-doc.cn
