Spring Boot Actuator

2. What Is An Actuator?

Actuators enable production-ready features to a Spring Boot application – without having to actually implement these things yourself.

They’re mainly used to expose different types of information about the running application – health, metrics, info, dump, env etc. And while these are no replacement for a production-grade monitoring solution – they’re a very good starting point.

http://localhost:8080/env
http://localhost:8080/health

Allows the application to be gracefully shutdown (not enabled by default).
