类 ReactiveResourceSynchronization<O,​K>

    • 方法详细资料

      • beforeCommit

        public reactor.core.publisher.Mono<Void> beforeCommit​(boolean readOnly)
        从接口复制的说明: TransactionSynchronization
        Invoked before transaction commit (before "beforeCompletion").

        This callback does not mean that the transaction will actually be committed. A rollback decision can still occur after this method has been called. This callback is rather meant to perform work that's only relevant if a commit still has a chance to happen, such as flushing SQL statements to the database.

        Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.

        指定者:
        beforeCommit 在接口中 TransactionSynchronization
        参数:
        readOnly - whether the transaction is defined as read-only transaction

        TransactionSynchronization.beforeCompletion()

      • afterCommit

        public reactor.core.publisher.Mono<Void> afterCommit()
        从接口复制的说明: TransactionSynchronization
        Invoked after transaction commit. Can perform further operations right after the main transaction has successfully committed.

        Can e.g. commit further operations that are supposed to follow on a successful commit of the main transaction, like confirmation messages or emails.

        NOTE: The transaction will have been committed already, but the transactional resources might still be active and accessible. As a consequence, any data access code triggered at this point will still "participate" in the original transaction, allowing to perform some cleanup (with no commit following anymore!), unless it explicitly declares that it needs to run in a separate transaction. Hence: Use PROPAGATION_REQUIRES_NEW for any transactional operation that is called from here.

      • shouldUnbindAtCompletion

        protected boolean shouldUnbindAtCompletion()
        Return whether this holder should be unbound at completion (or should rather be left bound to the thread after the transaction).

        The default implementation returns true.

      • shouldReleaseBeforeCompletion

        protected boolean shouldReleaseBeforeCompletion()
        Return whether this holder's resource should be released before transaction completion (true) or rather after transaction completion (false).

        Note that resources will only be released when they are unbound from the thread (shouldUnbindAtCompletion()).

        The default implementation returns true.

        releaseResource(O, K)

      • shouldReleaseAfterCompletion

        protected boolean shouldReleaseAfterCompletion​(O resourceHolder)
        Return whether this holder's resource should be released after transaction completion (true).

        The default implementation returns !shouldReleaseBeforeCompletion(), releasing after completion if no attempt was made before completion.

        releaseResource(O, K)

      • processResourceAfterCommit

        protected reactor.core.publisher.Mono<Void> processResourceAfterCommit​(O resourceHolder)
        After-commit callback for the given resource holder. Only called when the resource hasn't been released yet (shouldReleaseBeforeCompletion()).
        参数:
        resourceHolder - the resource holder to process

      • releaseResource

        protected reactor.core.publisher.Mono<Void> releaseResource​(O resourceHolder,
                                                            K resourceKey)
        Release the given resource (after it has been unbound from the thread).
        参数:
        resourceHolder - the resource holder to process
        resourceKey - the key that the resource object was bound for

      • cleanupResource

        protected reactor.core.publisher.Mono<Void> cleanupResource​(O resourceHolder,
                                                            K resourceKey,
                                                            boolean committed)
        Perform a cleanup on the given resource (which is left bound to the thread).
        参数:
        resourceHolder - the resource holder to process
        resourceKey - the key that the resource object was bound for
        committed - whether the transaction has committed (true) or rolled back (false)
