Spring 3.1.1 + Struts 2.3.1.2 + Hibernate 4.1 整合(SSH)
最近一直有朋友在问,最新版的Spring、Struts、Hibernate整合老是有问题,昨晚大概看了一下。从Hibernate 4 开始,本身已经很好的实现了数据库事务模块,而Spring也把Hibernate4之后的HibernateDaoSupport去掉了,Spring建议使用官方的HibernateAPI进行操作。这样一来,以前习惯使用HibernateDaoSupport来操作的人来说刚刚开始可能有些不习惯。我跟据官方的说明,大概的整合一下。
现在把主要的代码和配置贴出来,供大家参考,其它配置文件和代码和以前没有什么大变化,直接就能用,主要就是Dao。
