Method Summary

Modifier and Type	Method	Description
default void	close()	等效于txClose()
void	txClose()	提交事务 提交前需要执行txSuccess()或txFailure()否则默认回滚
void	txFailure()	标记事务失败 标记完毕后即可调用txClose()或close()回滚
long	txId()	事务Id
boolean	txIsFailure()	事务是否被标记为失败
boolean	txIsOpen()	事务是否仍然存活
boolean	txIsSuccess()	事务是否被标记为成功
void	txSuccess()	标记事务成功 标记完毕后即可调用txClose()或close()提交
