Application exception overridden by commit exception

 ERROR TransactionInterceptor:307 - Application exception overridden by commit exception

       ：

Remember only unchecked exceptions cause rollbacks in spring transactions.

What is happening is that you're catching the unchecked exception, converting it to a checked exception and then propogating it. The transaction manager does not rollback for RecordExistsException and thinks that your first transaction has succeded. Thats why it tries to save your child objects. You should annotate your service with 

  
 
   

    Code:
   
 
   
@Transactional (rollbackFor= RecordExistsException.class)
  
or have your exception class extend RuntimeException. 
    ：
  
OK, the way I read that an exception occurs and it does indeed do a commit. I would presume there must be a rollback rule defined telling it to do this.

Before Spring2.0 might look like this.

<prop key="*">PROPAGATION_REQUIRED, -com.mydomain.exception.MyException</prop>
