我需要在 Filter for spring mvc 中初始化休眠会话，我知道我需要在 web.xml 中添加 ContextListner 但我不知道在 applicationContext.xml 文件中写什么。请指导一些教程或示例......
详细说明：我需要使用 spring 表单标签预填充我的表单，因为我需要在 jsp 生命周期执行中打开 HibernateSession。我创建了一个 HibernateSessionFilter 来在 jsp 中启用休眠会话。现在再次为此我需要初始化我的休眠会话。见
sf = //不知道写什么;
在下面的代码中。我不知道如何在那里获得休眠 sessionFactory。我知道它可以通过 applicationContext.xml 完成，但无法获得所需的确切配置。

现在再次回到我开始的同一个异常：
