Method Summary

All Methods Instance Methods Abstract Methods Default Methods
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
