集成 Spring 和 Hibernate 3. 应用程序在创建 bean 时抛出异常
Integrating Spring and Hibernate 3. Application throws exception when creating the beans
下午好!我开始使用框架 Spring 和 Hibernate 研究依赖注入和控制反转以及数据持久性。我正在尝试使用 Spring 集成两者来控制由 Spring 监视的所有组件的 Hibernate SessionFactory 可以接收作为依赖 SessionFactory,Spring 控制 everything.Unfortunately 我不能为了实现这个目标,我得到以下异常:

从他所说的无法创建 bean 到 "SessionFactory" 因此无法创建用于数据持久化的 beans,"DAOS"。我已经遇到这个问题一个星期了,我已经看到并审查了应用程序中的设置-config.xml,尝试了很多东西,我尝试了论坛但我尝试过的都没有用,现在我请求你的帮助。
