Spring shutdown event that fires just before an ApplicationContext is destroyed?

I am looking for an interceptor or trigger to know that the entire beans context is destroyed, and the applicationcontext instance is about to destroy itself. Therefore, I can do one process at the end of the life of the application.

There is a type of ContextClosedEvent event that is close to what I want to do, but it throws an event after the beans are destroyed. I do this using the close () method of the contexttext application. So it does not fit my need

Any ideas?

You can use the registerShutDownHook () method of the abstract application's context class. For more information, see this.

UPDATE

Then you should try the @PreDestroy annotation on top of the method in which you want to run something at the end when the spring context is about to destroy.

Hope this helps you. Greetings.

Create a bean that implements SmartLifecycle, with getPhase returning Integer.MAX_VALUE. Its stop () method will be executed before any other stop or destroy methods. You can do a cleanup on all resources in live beans.

  @Component public class Terminator implements SmartLifecycle { private boolean started = true; @Override public void stop() { // CLEANUP CODE } @Override public void stop(Runnable callback) { stop(); callback.run(); } @Override public int getPhase() { return Integer.MAX_VALUE; } @Override public boolean isAutoStartup() { return true; } @Override public boolean isRunning() { return started; } }  0   08 .
