Spring 4 + hibernate 4 - HibernateException: No Session found for current thread - spring

Question

I've read all of the other questions/answers about this issue but still missing something for me. Can anyone help?
I've found that <prop key="hibernate.current_session_context_class">thread</prop> partially works but it seams that it's not the spring current session so i commented it (if I use it, it will give this: HibernateException: get is not valid without active transaction).

Answer 1

In your code loadUserByUsername (which is not #Transactional) invokes getUserByEmail. Although it's marked #Transactional, the annotation (proxying) will not take effect because both methods belong to same class. In most cases the best is to mark whole #Service class with #Transactional annotation.
