My Database table has mismatch column name with the Java Object   Entity  which leads to throw the above exception  By updating the table with appropriate column name resolves this issue

Thanks for comment of mannedear  I use springmvc and in my case I have to use as   Repository  Transactional  EnableTransactionManagement public class UserDao           and I also add spring-context to pom xml and it works

Check your dao class  It must be like this    Session session   getCurrentSession    Query query   session createQuery GET ALL     And annotations    Transactional  Repository

I have had the same issue  but in a class that was not a part of the service layer  In my case  the transaction manager was simply obtained from the context by the getBean   method  and the class belonged to the view layer - my project utilizes OpenSessionInView technique   The sessionFactory getCurrentSession   method  has been causing the same exception as the author s  The solution for me was rather simple   Session session   try       session   sessionFactory getCurrentSession      catch  HibernateException e        session   sessionFactory openSession        If the getCurrentSession   method fails  the openSession   should do the trick

I had the same issue  I resolved it doing the following    Add the this line to the dispatcher-servlet file        lt tx annotation-driven  gt     Check above  lt beans gt  section in the same file  These two lines must be present       xmlns tx  http   www springframework org schema tx  xsi schemaLocation   http   www springframework org schema tx http   www springframework org schema tx spring-tx xsd    Also make sure you added  Repository and  Transactional where you are using sessionFactory     Repository  Transactional public class ItemDaoImpl implements ItemDao        Autowired     private SessionFactory sessionFactory

I had this error too because in the file where I used  Transactional  annotation  I was importing the wrong class  import javax transaction Transactional     Instead of javax  use  import org springframework transaction annotation Transactional

User · Answer

Transactional  javax transaction Transactional  Put it just beside  Repository

User · Answer

My solution was  using Spring  putting the method that fails inside another method that creates and commits the transaction   To do that I first injected the following    Autowired private PlatformTransactionManager transactionManager    And finally did this   public void newMethod         DefaultTransactionDefinition definition   new DefaultTransactionDefinition        TransactionStatus transaction   transactionManager getTransaction definition        oldMethod         transactionManager commit transaction

My configuration was like this  I had a QuartzJob   a Service Bean   and Dao   as usual it was configured with LocalSessionFactoryBean  for hibernate    and SchedulerFactoryBean for Quartz framework   while writing the Quartz job   I by mistake annotated it with  Service   I should not have done that because I was using another strategy to wire the QuartzBean using AutowiringSpringBeanJobFactory extending SpringBeanJobFactory    So what actually was happening is that due to Quartz Autowire   TX was getting injected to the Job Bean and at the same time Tx Context was set by virtue of  Service annotation and hence the TX was falling out of sync       I hope it help to those for whom above solutions really didn t solved the issue   I was using Spring 4 2 5 and Hibernate 4 0 1     I see that in this thread there is a unnecessary suggestion to add  Transactional annotation to the DAO  Repository    that is a useless suggestion cause  Repository has all what it needs to have don t have to specially set that  transactional on DAOs   as the DAOs are called from the services which have already being injected by  Trasancational   I hope this might be helpful people who are using Quartz   Spring and Hibernate together

I encountered the same problem and finally found out that the  lt tx annotaion-driven   gt  was not defined within the  dispatcher -servlet xml where component-scan element enabled  service annotated class    Simply put  lt tx annotaion-driven   gt  with component-scan element together  the problem disappeared

In this class above  Repository just placed one more annotation  Transactional it will work  If it works reply back Y N     Repository  Transactional public class StudentDAOImpl implements StudentDAO

Add transaction-manager to your  lt annotation-driven  gt  in spring-servlet xml    lt tx annotation-driven transaction-manager  yourTransactionBeanID   gt

User · Answer

You must enable the transaction support   lt tx annotation-driven gt  or  EnableTransactionManagement  and declare the transactionManager and it should work through the SessionFactory   You must add  Transactional into your  Repository  With  Transactional in your  Repository Spring is able to apply transactional support into your repository   Your Student class has no the  javax persistence   annotations how  Entity  I am assuming the Mapping Configuration for that class has been defined through XML

You need to allow transaction to your DAO method  Add    Transactional readOnly   true  propagation Propagation NOT SUPPORTED    over your dao methods  And  Transactional should be from the package   org springframework transaction annotation Transactional

Add the annotation  Transactional of spring in the class service
