javax.transaction
Interface Synchronization

public interface Synchronization

The transaction manager supports a synchronization mechanism that allows the interested party to be notified before and after the transaction completes. Using the registerSynchronization method, the application server registers a Synchronization object for the transaction currently associated with the target Transaction object. 事务管理器支持同步机制以允许在事务完成以后通知感兴趣者。 使用registerSynchronization方法，应用服务器为当前同目标Transaction对象关联事务注册一个Synchronization对象。
