Answer 1

You need to do db update operation (insert, update, delete) within transaction boundary .
Session session = getCurrentSession();
Transaction trans = session.beginTransaction(); //begin transaction
//db operation
session.save(test)
trans.commit(); //end transaction
OR
For annotation support, in your spring config bean, add this
<tx:annotation-driven transaction-manager="transactionManager" mode="proxy" proxy-target-class="true" />

Answer 2

Remove this tag from sessionFactory -> hibernateProperties
<property name="hibernate.current_session_context_class">thread</property>
