启动异常：
java.lang.ClassCastException: org.springframework.orm.hibernate4.SessionHolder cannot be cast to org.springframework.orm.hibernate3.SessionHolder
由于hibernate4已经完全可以实现事务了 与spring3.1中的hibernatedao,hibernateTemplete等有冲突，所以spring3.1里已经不提供hibernatedaosupport,hibernateTemplete了，只能用hibernate原始的方式用session。 获得session：getSessionFactory().getCurrentSession()。
