本文整理了Java中org.hibernate.Transaction.begin()方法的一些代码示例，展示了Transaction.begin()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.begin()方法的具体详情如下：
包路径：org.hibernate.Transaction
类名称：Transaction
方法名：begin

Transaction.begin介绍

[英]Begin this transaction. No-op if the transaction has already been begun. Note that this is not necessarily symmetrical since usually multiple calls to #commit or #rollback will error.
[中]开始这个交易。如果交易已经开始，则无操作。请注意，这不一定是对称的，因为通常多次调用#提交或#回滚都会出错。
