方法详细资料

• getOrder

  public int getOrder()

  从接口复制的说明: Ordered
  Get the order value of this object.

  Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

  Same order values will result in arbitrary sort positions for the affected objects.

  指定者:

  getOrder 在接口中 Ordered

  覆盖:

  getOrder 在类中 TransactionSynchronizationAdapter

  返回:

  the order value

  Ordered.HIGHEST_PRECEDENCE, Ordered.LOWEST_PRECEDENCE

• beforeCompletion

  public void beforeCompletion()

  从接口复制的说明: TransactionSynchronization
  Invoked before transaction commit/rollback. Can perform resource cleanup before transaction completion.

  This method will be invoked after beforeCommit, even when beforeCommit threw an exception. This callback allows for closing resources before transaction completion, for any outcome.

  指定者:

  beforeCompletion 在接口中 TransactionSynchronization

  覆盖:

  beforeCompletion 在类中 TransactionSynchronizationAdapter

  另请参阅:

  TransactionSynchronization.beforeCommit(boolean), TransactionSynchronization.afterCompletion(int)

• afterCompletion

  public void afterCompletion​(int status)

  从接口复制的说明: TransactionSynchronization
  Invoked after transaction commit/rollback. Can perform resource cleanup after transaction completion.

  NOTE: The transaction will have been committed or rolled back 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.

  指定者:

  afterCompletion 在接口中 TransactionSynchronization

  覆盖:

  afterCompletion 在类中 TransactionSynchronizationAdapter

  参数:

  status - completion status according to the STATUS_* constants
