Call a method at Spring Boot application crash

Question

For my use case, I wanted to invoke a method doSomething() under three scenarios:

1. When my Spring Boot application has started. [Done]
2. When my Spring Boot application is shutting down. [Done]
3. When my Spring Boot application has crashed. [Pending]

Basically, an application crash is a type of application shutdown. But I am looking for a way to differentiate between the two. I want to pass the exception which has caused the application to crash to doSomething(ex) as well.

Can I achieve this through ContextClosedEvent or is there another way to achieve the functionality?

Answer 1

is it ok using @PreDestroy?

import org.springframework.stereotype.Component;
import javax.annotation.PreDestroy;

@Component
public class MyService  {

    @PreDestroy
    public void predestory() {
        System.out.println("--------using predestoy-----");
    }
}
