Spring mvc Hibernate 集成

Question

spring mvc中如何集成hibernateUtil和hibernate.cgf.xml？ Witch XML 文件我应该配置 dao-context.xml 还是 store-servlet.xml？ enter image description here

Store-servlet.xml

spring mvc中如何集成hibernateUtil和hibernate.cgf.xml？

• hibernate.cfg.xml：这是主要的休眠配置文件，用于加载实体的数据库配置和映射文件。这必须是项目中的类路径位置。默认情况下，hibernate 会查找类路径目录的根目录。如果要使用不同的位置，则必须在加载配置时将位置传递给配置对象。在这里您必须定义数据库详细信息和映射文件位置。

• hibernateUtil：实际上，spring mvc 中并没有集成这个类。所以它是实现 DAO 和手动控制 Hibernate 会话和事务的简单方法。
