I'm building a new dynamic website and I created 2 DAO class in Spring MVC to manage the query in 2 different tables. I need to know how can i manage 2 DAO methods in a single transaction, using Hibernate...Pratically, I create 2 DAO Java classes and related implementation class:
First DAO class (FirstDAOImpl.java):
@Transactional(readOnly = false, rollbackFor=Exception.class)
public void insertUser(User user)
{
//do insert an user using hibernate...
}
Second DAO class (SecondDAOImpl.java):
@Transactional(rollbackFor=Exception.class)
public void insertUserRole(UserRole register)
{
//do insert user role using hibernate...
}
In my Spring controller, i need to call both DAO method in a single transaction...
Actually, I have a new transactional method for any DAO method:
@RequestMapping(value = "/new-user", method = RequestMethod.POST)
public String insertNewUser(Model model)
{
//Other code
try
{
firstDAO.insertUser(myUserObject);
secondDAO.insertUserRole(myUserRoleObject);
}
catch(Exception e)
{
logger.info("exception!");
}
//Other code
}
When the method insertUserRole() to insert a new record fails, the transaction for the previous method insertUser() is executed succesfully without rollback!
How can I manage these 2 methods in a single transaction? I would keep separates these 2 operations...
Thanks! :)
You need to call the DAO methods from another method with @Transactional.
The transaction will then be created outside of the DAO methods, and they will use the existing transaction (due to the default propagation) instead of creating their own new ones.
