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

SessionFactory.getCurrentSession介绍

[英]Obtains the current session. The definition of what exactly "current" means controlled by the org.hibernate.context.spi.CurrentSessionContext impl configured for use.

Note that for backwards compatibility, if a org.hibernate.context.spi.CurrentSessionContextis not configured but JTA is configured this will default to the org.hibernate.context.internal.JTASessionContextimpl.
[中]获取当前会话。“当前”的确切含义由组织控制。冬眠上下文spi。CurrentSessionContext impl已配置为可供使用。
请注意，为了向后兼容，如果一个组织。冬眠上下文spi。CurrentSessionContext未配置，但配置了JTA。这将默认为组织。冬眠上下文内部的JTASessionContextimpl。
