[SOLVED] Transactional annotation on whole class + excluding a single method

Transactional annotation on whole class + excluding a single method

I have a class with @Transactional annotation (instead of marking it for all of its method).

Although i have a single method inside that class that shouldn't be annotated as @Transactional.

My question is is there an annotation i can put in this method to mark it as "non-transactional"? or should i start marking each single method in this class as "transactional" excluding this method (a lot of work)

thanks.

Solution

There are different transaction propagation strategies to use. These exist in the enum Propagation. The ones you might want to use are

/**
 * Execute non-transactionally, suspend the current transaction if one exists.
 * Analogous to EJB transaction attribute of the same name.
 * <p>Note: Actual transaction suspension will not work on out-of-the-box
 * on all transaction managers. This in particular applies to JtaTransactionManager,
 * which requires the {@code javax.transaction.TransactionManager} to be
 * made available it to it (which is server-specific in standard J2EE).
 * @see org.springframework.transaction.jta.JtaTransactionManager#setTransactionManager
 */
NOT_SUPPORTED(TransactionDefinition.PROPAGATION_NOT_SUPPORTED),

/**
 * Execute non-transactionally, throw an exception if a transaction exists.
 * Analogous to EJB transaction attribute of the same name.
 */
NEVER(TransactionDefinition.PROPAGATION_NEVER), // maybe not this one

So annotate the method inside your class with either of these.

@Transactional
public class MyTransactionalClass { 
    @Transactional(propagation = Propagation.NOT_SUPPORTED)
    public void nonTransactionalMethod() {...}
}

You can find all the propagation strategies here.
