接口 TransactionStatus
public interface TransactionStatus extends TransactionExecution, SavepointManager, Flushable
Representation of the status of a transaction.Transactional code can use this to retrieve status information, and to programmatically request a rollback (instead of throwing an exception that causes an implicit rollback).
Includes the
SavepointManagerinterface to provide access to savepoint management facilities. Note that savepoint management is only available if supported by the underlying transaction manager.- 从以下版本开始:

方法详细资料
hasSavepoint
boolean hasSavepoint()
Return whether this transaction internally carries a savepoint, that is, has been created as nested transaction based on a savepoint.This method is mainly here for diagnostic purposes, alongside
TransactionExecution.isNewTransaction(). For programmatic handling of custom savepoints, use the operations provided bySavepointManager.
flush
void flush()
Flush the underlying session to the datastore, if applicable: for example, all affected Hibernate/JPA sessions.This is effectively just a hint and may be a no-op if the underlying transaction manager does not have a flush concept. A flush signal may get applied to the primary resource or to transaction synchronizations, depending on the underlying resource.
