title: Spring Hibernate transaction management
body: <p>I have just started making a project using spring and hibernate. My DAO layer class extends HibernateDaoSupport. We are not using annotations. 
  Earlier, we were using struts, hence we used getTransaction, commit, rollback .. methods provided by Session class.
  My requirement is very simple, for all DAO classes, if there is an exception, rollback otherwise commit. Please suggest a simplest way of introducing spring transaction management. </p>
