Health check back-end only spring-boot application (message processing application)

Question

I do have a kafka message processing spring-boot applicattion without any rest controller or api and without any port.

Is there a way I could check the status of the application as if it is up or down?

Answer 1

Spring Boot has a feature called "Actuators" which configures endpoints for checking system's health and other details.

Actuators

you can simply add them to your application and you don't need to code any rest controllers.
