public @interface Transactional

If it isn't possible to use EJBs, this interceptor adds transaction support to methods or a class. The optional qualifier can be used to specify different entity managers.

Further details can be found at TransactionScoped which is an optional scope which can be used together with @Transactional.

Element Detail

qualifier

public abstract Class<? extends java.lang.annotation.Annotation>[] qualifier

Optional qualifier/s which allow/s to start only specific transactions instead of one for the injected EntityManagers. Default-value is Any which means any injected EntityManagers should be detected automatically and transactions for all injected EntityManagers will be started. Or the Default EntityManager will be used, if no qualifier and no EntityManager was found (in the annotated class) (see DELTASPIKE-320). This qualifier can also be used for integrating other frameworks, which follow a different style (see DELTASPIKE-319) as well as the usage of EntityManagers with qualifiers in a called method (of a different bean) which isn't Transactional itself.

Returns:

target persistence-unit identifier

Default:

javax.enterprise.inject.Any.class

readOnly

public abstract boolean readOnly

Only evaluated on the first/outermost transactional bean/method in the chain

Returns:

true to trigger #rollback for the current transaction(s), false otherwise

Default:

false
