REQUIRES_NEW在Spring + Hibernate中不创建新交易

Question

I have a Spring and hibernate application (both latest version) and I have 2 beans as mentioned below

@Component
public class Bean1{

@Autowired 
Bean2 bean2;

@Transactional(propagation = Propagation.REQUIRED)
public void foo()
{
    bean2.bar();
}


@Component
public class Bean2{

@Transactional(propagation = Propagation.REQUIRES_NEW)
public void bar()
{
    try{
           // Do something which throws exception
    }
    catch (Exception e) {
        log & eat the exception here only.
        But inspite of this the outer transaciton gets rolled back
    }
}

The issue is that when bean2.bar causes any exception (eg foreign Key ConstraintViolationException ) then it rolls back the outer transaction as well saying " Transaction rolled back because it has been marked as rollback-only","moreInfo":""}"

On seeing hibernate logs I found only one line for "new transaction"

D| o.s.o.h.HibernateTransactionManager- Creating new transaction with name ... PROPAGATION_REQUIRED,ISOLATION_DEFAULT; ''

which means no new transaction is getting created for the inner bean2.bar();

I am not able to find out what's wrong here? Any help is greatly appreciated.

REQUIRES_NEW applies to JTA transaction Managers only. Refer Spring Doc here

REQUIRES_NEW
public static final Propagation REQUIRES_NEW

Execute non-transactionally, suspend the current transaction if one exists. Analogous to EJB transaction attribute of the same name.
Note: Actual transaction suspension will not work on out-of-the-box on all transaction managers. This in particular applies to JtaTransactionManager, which requires the javax.transaction.TransactionManager to be made available it to it (which is server-specific in standard J2EE).
