Question

I have the following code. I want the execution to continue even if there is an exception

@Transactional(noRollbackFor={PersistenceException.class, PSQLException.class,SQLGrammarException.class})
public void executeQuery(String parameterName){
    Query query = objectManager.getEntityManager().createNativeQuery("SOME UPDATE QUERY");

    Map<String, String> paramMap = (Map) destTableMap.get(parameterName);
    query.setParameter("xyz",5);

    try{
        query.executeUpdate();
    }catch(Exception ex){
         ex.printStackTrace();
    }
}

The exception stack trace that I receive is

Exception in thread "main" org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rollbackOnly

From the documentation:

If the Session throws an exception, including any SQLException,
immediately rollback the database transaction, call Session.close()
and discard the Session instance. Certain methods of Session will not
leave the session in a consistent state. No exception thrown by
Hibernate can be treated as recoverable. Ensure that the Session will
be closed by calling close() in a finally block.

The transaction must be rolled back. So, if you want to continue executing if Hibernate throws an exception, you should put the execute the executeQuery method in its own transaction, using the REQUIRES_NEW propagation in the @Transactional annotation. This way, only this short transaction will be rolled back.
