Execution code after transaction

[smklimenko]

Hi.
I have the following problem: I need executed some code after transaction was commited. For example:

class MyManager {
     @Transactional
     public void doSomething() {
          // Code required transaction
          myDao.doSomethingWihDao(); 
          
         // Code MUST by executed after transaction
         listeners.fireEvent();
     }
}

The main problem that transaction created outside of method doSomething() but events which fired in this method should be fired after transaction.
I can't start new transaction here because active session locks some data (for example lazy collections in Hibernate).

I think it will be good have something like:

class MyManager {
     @Transactional
     public void doSomething() {
          // Code required transaction
          myDao.doSomethingWihDao(); 
          
         // Code MUST by executed after transaction
         fireEvent();
     }

     @AfterTransactionCommited
     protected void fireEvent() {
         listeners.fireEvent();
     }
}

or something like:

class MyManager {
     @Transactional
     public void doSomething() {
          // Code required transaction
          myDao.doSomethingWihDao(); 

         TransactionUtil.afterTransactionCommited(new Runnable()) { 
                public void run() {
                  // Code MUST by executed after transaction
                 listeners.fireEvent();
               }
         }
     }
}

1) Create an aspect which runs after the transaction (use an after advice or if it is only for succesful transactions a after-returning advice)
2) Use the TransactionSynchronization to execute the listeners.

I would suggest 1 because that is a bit simpler to implement and create.
