Spring BootThere are four great artifact, namely auto-configuration, starters, CLI and actuator. This article mainly talks about actuator. Actuator is the set of introspection and monitoring of application systems provided by spring boot.The success is able to configure the application system to see and function related statistics.

Using actuator

  • Add dependency

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
