本文整理了Java中org.hibernate.Transaction.commit()方法的一些代码示例，展示了Transaction.commit()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Transaction.commit()方法的具体详情如下：
包路径：org.hibernate.Transaction
类名称：Transaction
方法名：commit

Transaction.commit介绍

[英]Commit this transaction. This might entail a number of things depending on the context:

  • If this transaction is the #isInitiator, Session#flush the Sessionwith which it is associated (unless Session is in FlushMode#MANUAL).
  • If this transaction is the #isInitiator, commit the underlying transaction.
  • Coordinate various callbacks
    [中]提交此事务。根据具体情况，这可能需要做很多事情：
    *如果此事务是#isInitiator，则会话#刷新与其关联的会话（除非会话处于刷新模式#手动）。
    *如果此事务是#isInitiator，则提交基础事务。
    *协调各种回调
