I am looking for an interceptor or a trigger to know that, all the context beans are destroyed and the applicationcontext instance is about to destroy itself. So I can do one process at the end of the application lifetime.
There is this event type ContextClosedEvent, which is close to the thing that I wanna do but, it throws the event after destruction of beans. I thing it comes with the close() method of the applicationcontext. So it doesn't fit to my need
Any ideas?

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.
During a graceful shutdown Spring Boot allows some grace period to the application to finish all the current requests or processes. Once, the grace period is over the unfinished processes or requests are just killed. By default, Spring Boot allows a 30 seconds graceful shutdown timeout.
Close ApplicationContext Another option to shutdown the Spring Boot application is to close Spring ApplicationContext using SpringApplication . SpringApplication. run(String…) method returns ApplicationContext as a ConfigurableApplicationContext We can use close() method to close ApplicationContext programmatically.
You can use registerShutDownHook() method of the abstract application context class. For more details have a look at this.
UPDATE
Then you should try @PreDestroy annotation on top of the method where you want to run something in the end when the spring context is about to destroy.
Hope this helps you. Cheers.
