if i remove this property no exception is occurred.

My code is like below :

  @Service
    Class ABCServiceImpl 
{
    @Transactional
    void methodA()
    {
       // called the method in DAOImpl package -- methodB().
    }

}

@Repository
Class ABCDAOImpl
{
    @Autowired
    SessionFectory s;

    void methodB()
    {
      // hibernate operatoion
    }

}

Thanks in advance.

  1. Try to close the connection manually. and
  2. use .openSession(); method to open session instead of .getCurrentSession(); no exception comes.

If this flag is set to true then session will be automatically closed during the after completion phase of the transaction. Agree with Edward on what you are trying to implicitly close the connection throwing that Exception.

The problem is that you cant call close() twice on a Session, the second time you call the close() method, it will throw that Exception.

By setting auto_close you are implicitly closing the session after you use it, so the solution would be removing the close() methods in your code, or just remove that auto_close config and close the sessions manually after using them.
