Spring in Action, Sixth Edition
Spring Boot Actuator is a Spring Boot module that exposes operational and management information about a running application.
- How it is used
- Provides operational visibility and limited control of a running Spring Boot application through management endpoints.
- How deep it goes
- Shows starter setup, endpoint requests, health configuration, exposure settings, and security matching; defers JMX endpoint treatment.
- Examples
- Uses curl requests for /actuator/info and /actuator/health, YAML contact properties, and a ROLE_ADMIN endpoint matcher.
- What you can do after
- Operate/configure it by adding the Maven starter, inspecting HTTP endpoints, selecting exposure, and restricting access with Spring Security.
