javax.transaction
Interface Transaction

public interface Transaction

The Transaction interface allows operations to be performed against the transaction in the target Transaction object. A Transaction object is created corresponding to each global transaction creation. The Transaction object can be used for resource enlistment, synchronization registration, transaction completion, and status query operations. Transaction接口允许操作执行基于目标Transaction对象的事务。创建一个Transaction对象 符合每一个全局事务创建。Transaction对象可以用于资源征集、同步注册、事务完成和状态查询操作。

commit

Complete the transaction represented by this Transaction object. 完成Transaction对象表示的事务。

Throws:

RollbackException - Thrown to indicate that the transaction has been rolled back rather than committed. 抛出表示事务已被回滚而不是提交。

HeuristicMixedException - Thrown to indicate that a heuristic decision was made and that some relevant updates have been committed while others have been rolled back. 抛出表示试探性决定已经作出，某些相关更新已提交，然而其它一些被回滚。

HeuristicRollbackException - Thrown to indicate that a heuristic decision was made and that all relevant updates have been rolled back. 抛出表示试探性决定已经做出，但所有相关更新已回滚。

SecurityException - Thrown to indicate that the thread is not allowed to commit the transaction. 抛出表示当前线程不允许提交事务。

IllegalStateException - Thrown if the transaction in the target object is inactive. 如果目标对象的事务为非活动状态则抛出。

SystemException - Thrown if the transaction manager encounters an unexpected error condition. 如果事务管理器遭遇无法预料错误的情况时抛出。

<!-- -->

delistResource

Disassociate the resource specified from the transaction associated with the target Transaction object. 解除与目标Transaction对象关联的事务指定的资源关联。

Parameters:

xaRes - The XAResource object associated with the resource (connection). 与资源关联的XAResource对象（连接）。

flag - One of the values of TMSUCCESS, TMSUSPEND, or TMFAIL. TMSUCCESS、TMSUSPEND或者TMFAIL值之一。

Returns:

true if the resource was delisted successfully; otherwise false. 如果资源已成功被解除，返回true，否则为false。

Throws:

IllegalStateException - Thrown if the transaction in the target object is inactive. 如果目标对象的事务为非活动状态则抛出。

SystemException - Thrown if the transaction manager encounters an unexpected error condition. 如果事务管理器遭遇无法预料错误的情况时抛出。

<!-- -->

enlistResource

Enlist the resource specified with the transaction associated with the target Transaction object. 加入与目标Transaction对象关联的事务指定的资源。

Parameters:

xaRes - The XAResource object associated with the resource (connection). 与资源关联的XAResource对象（连接）。

Returns:

true if the resource was enlisted successfully; otherwise false. 如果资源已成功被加入，返回true，否则为false。

Throws:

RollbackException - Thrown to indicate that the transaction has been marked for rollback only. 抛出表示事务已被标记为仅回滚。

IllegalStateException - Thrown if the transaction in the target object is in the prepared state or the transaction is inactive. 如果目标对象的事务在准备状态或者为非活动状态则抛出。

SystemException - Thrown if the transaction manager encounters an unexpected error condition. 如果事务管理器遭遇无法预料错误的情况时抛出。

<!-- -->

getStatus

Obtain the status of the transaction associated with the target Transaction object. 获取与目标Transaction对象关联的事务状态。

Returns:

The transaction status. If no transaction is associated with the target object, this method returns the Status.NoTransaction value. 事务状态。如果当前线程没有关联事务，方法返回Status.NoTransaction值。

Throws:

SystemException - Thrown if the transaction manager encounters an unexpected error condition. 如果事务管理器遭遇无法预料错误的情况时抛出。

<!-- -->

registerSynchronization

Register a synchronization object for the transaction currently associated with the target object. The transction manager invokes the beforeCompletion method prior to starting the two-phase transaction commit process. After the transaction is completed, the transaction manager invokes the afterCompletion method. 为目前与目标对象关联的事务注册一个同步对象。事务管理器在开始两步事务提交过程前调用 beforeCompletion方法。事务完成后，事务管理器调用afterCompletion方法。

Parameters:

sync - The Synchronization object for the transaction associated with the target object. 与目标对象关联事务的Synchronization对象。

Throws:

RollbackException - Thrown to indicate that the transaction has been marked for rollback only. 抛出表示事务已被标记为仅回滚。

IllegalStateException - Thrown if the transaction in the target object is in the prepared state or the transaction is inactive. 如果目标对象的事务在准备状态或者为非活动状态则抛出。

SystemException - Thrown if the transaction manager encounters an unexpected error condition. 如果事务管理器遭遇无法预料错误的情况时抛出。

<!-- -->

rollback

Rollback the transaction represented by this Transaction object. 回滚Transaction对象表示的事务。

Throws:

IllegalStateException - Thrown if the transaction in the target object is in the prepared state or the transaction is inactive. 如果目标对象的事务在准备状态或者为非活动状态则抛出。

SystemException - Thrown if the transaction manager encounters an unexpected error condition. 如果事务管理器遭遇无法预料错误的情况时抛出。

<!-- -->

setRollbackOnly

Modify the transaction associated with the target object such that the only possible outcome of the transaction is to roll back the transaction. 修改当前线程的关联事务，使得事务的唯一可能结果是回滚该事务。

Throws:

IllegalStateException - Thrown if the target object is not associated with any transaction. 如果目标对象没有和关联任何事务时抛出。

SystemException - Thrown if the transaction manager encounters an unexpected error condition. 如果事务管理器遭遇无法预料错误的情况时抛出。
