linux - How to shutdown a Spring Boot Application in a correct way?

Question

In the Spring Boot Document, they said that 'Each SpringApplication will register a shutdown hook with the JVM to ensure that the ApplicationContext is closed gracefully on exit.'

When I click ctrl+c on the shell command, the application can be shutdown gracefully. If I run the application in a production machine, I have to use the command java -jar ProApplicaton.jar. But I can't close the shell terminal, otherwise it will close the process.

If I run command like nohup java -jar ProApplicaton.jar &, I can't use ctrl+c to shutdown it gracefully.

What is the correct way to start and stop a Spring Boot Application in the production environment?

Answer 1

If you are using the actuator module, you can shutdown the application via JMX or HTTP if the endpoint is enabled.

add to application.properties:

endpoints.shutdown.enabled=true

Following URL will be available:

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

Depending on how an endpoint is exposed, the sensitive parameter may be used as a security hint.

For example, sensitive endpoints will require a username/password when they are accessed over HTTP (or simply disabled if web security is not enabled).
