How can I create a new transaction with HibernateTransactionManager by using @Transactional(propagation = Propagation.REQUIRES_NEW) but encountering an error?

edit

If you are encountering an error while trying to create a new transaction with HibernateTransactionManager by using @Transactional(propagation = Propagation.REQUIRES_NEW), there could be several reasons for the error. Here are some possible solutions:

1. Make sure that you have configured the HibernateTransactionManager properly in your Spring configuration file. You should define the transaction manager bean and set up the session factory, data source, and other required properties.

2. Check if you have set up the @EnableTransactionManagement annotation properly in your configuration file. This is required to enable Spring's declarative transaction management.

3. Verify that the @Transactional annotation is applied to the correct method in your code. Make sure that the transactional method is being called correctly and that it is annotated with @Transactional(propagation = Propagation.REQUIRES_NEW).

4. Ensure that the transactional method is being called from a different transactional method. @Transactional(propagation = Propagation.REQUIRES_NEW) creates a new transaction every time the method is called, so it should not be nested within a transaction.

5. Make sure that the error you are encountering is not related to database connectivity or data integrity. Check the database logs and error messages to see if there are any issues with the database.

6. Finally, if none of the above solutions work, try debugging your code to identify the source of the error. Add breakpoints and log statements to track the flow of the code and see where the error is occurring.
