Check if a transaction to database is finished in Spring

I have a @Component class with @Transactional annotation. In onApplicationEvent method I save same data in db and after that I call System.exit(0).

But data isn't saved and I want to check when the data is saved.

I use TransactionSynchronizationManager.isActualTransactionActive() but always is true.

How I can check safe if a transaction is finished?

1) Not sure it is latest, but you need a transaction interceptor, like that: https://docs.jboss.org/hibernate/core/3.6/javadocs/org/hibernate/Interceptor.html

and listen to afterTransactionCompletion(...)

2) you can simply wrap the DB calling method by try-catch and if calling method exited without exception - transaction is done. (in case you do not catch exceptions inside).

wrap your java code that calls the DB save like that:

try{
    saveData()...

    //transaction was OK here, I can System.exit
    System.exit();
}catch(Exception e){
     //transaction failed, I need so something
     soSomething();
}

What kind of ApplicationEvent do you listen to? If it is a custom event produced by your own code (via ApplicationEventPublisher) then you can put org.springframework.transaction.event.TransactionalEventListener annotation on your event-handling method and it will be invoked after transaction is committed. (if event was published of course)
