Hi  
I use hibernate 5.2.10 & spring boot 2.1.1 & JTA & Weblogic 12.2.2.1  
Now when we save any entity that has some constraint such as unique constraint & foreign key constraint … we get error but we could not get clear Exception in our back-end. Because our Exception catch in ResultSetReturnImpl and the result print with SqlExceptionHelper, so we could not catch those exception!!  
My code is

```auto
public viod add (T entity){
Session session = getSession();
try{
    session.save(entity);
}catch (TransactionException ex){
   System.out.println("++++++++"); // Do Not go here when throw exception for unique constraint
}
}

```

So we could not find any answer for this problem!  
Is there any answer??  
Could we override ResultSetReturnImpl and customize this method?

I found answer!!!  
It’s in spring configuration. I always use JTA for manage my transaction but should be use from JPA transaction for solve this issue.Like [This](https://www.baeldung.com/transaction-configuration-with-jpa-and-spring)
