Annotation Transactional How to rollback

Question

I used this annotation successfully for a Dao class  And rollback works for tests    But now I need to rollback real code  not just tests  There are special annotations for use in tests  But which annotations are for non-test code  It is a big question for me  I spent a day for that already   The official documentation did not meet my needs    class MyClass      this does not make rollback  And record appears in DB          EmployeeDaoInterface employeeDao           public MyClass                 ApplicationContext context   new ClassPathXmlApplicationContext                      new String      HibernateDaoBeans xml                  employeeDao    IEmployeeDao  context getBean  employeeDao                         Transactional rollbackFor  Exception class       public void doInsert  Employee newEmp   throws Exception           employeeDao insertEmployee newEmp           throw new RuntimeException              employeeDao is    Transactional public class EmployeeDao implements IEmployeeDao       private SessionFactory sessionFactory       public void setSessionFactory SessionFactory sessionFactory            this sessionFactory   sessionFactory             public void insertEmployee Employee emp            sessionFactory getCurrentSession   save emp             And here is a test for which the annotations work well     RunWith SpringJUnit4ClassRunner class   ContextConfiguration locations       HibernateDaoBeans xml      TransactionConfiguration transactionManager    txManager   defaultRollback   true   Transactional public class EmployeeDaoTest         Autowired     EmployeeDaoInterface empDao        Test     public void insert record                       assertTrue empDao insertEmployee newEmp            HibernateDaoBeans xml          lt bean id  employeeDao  class  Hibernate EmployeeDao  gt       lt property name  sessionFactory  ref  sessionFactory    gt   lt  bean gt       lt tx annotation-driven transaction-manager  txManager   gt    lt bean id  txManager  class  org springframework orm hibernate3 HibernateTransactionManager  gt       lt property name  sessionFactory  ref  sessionFactory    gt   lt  bean gt                   YES  I rolled back the transaction  I just added BEAN for the service    and then annotation  Transactional begin to work  -       lt bean id  service  class  main MyClass  gt       lt property name  employeeDao  ref  employeeDao    gt   lt  bean gt    Thanks all  Russia will not forget you

Just throw any RuntimeException from a method marked as  Transactional   By default all RuntimeExceptions rollback transaction whereas checked exceptions don t  This is an EJB legacy  You can configure this by using rollbackFor   and noRollbackFor   annotation parameters    Transactional rollbackFor Exception class    This will rollback transaction after throwing any exception

For me rollbackFor  was not enough  so I had to put this and it works as expected    Transactional propagation   Propagation REQUIRED  readOnly   false  rollbackFor   Exception class    I hope it helps  -

You can throw an unchecked exception from the method which you wish to roll back  This will be detected by spring and your transaction will be marked as rollback only   I m assuming you re using Spring here  And I assume the annotations you refer to in your tests are the spring test based annotations      The recommended way to indicate to the Spring Framework s transaction infrastructure that a transaction s work is to be rolled back is to throw an Exception from code that is currently executing in the context of a transaction    and note that      please note that the Spring Framework s transaction infrastructure code will  by default  only mark a transaction for rollback in the case of runtime  unchecked exceptions  that is  when the thrown exception is an instance or subclass of RuntimeException
