我的想法：
Hibernate：DaoImpl类继承HibernateDaoSupport，使用getHibernateTemplate()或者Session操作数据。
Spring：加进去什么都不干，就是使用C3P0。
Servlet：控制等等。
帮忙看看我的applicationContext.xml对不对：

Answer 1

java.lang.NoSuchMethodError:org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session

hibernate 4 中没有 HibernateDaoSupport，包括数据访问都不需要 hibernatetemplate，必须改写 dao，直接使用 hibernate 的 session 和 query 接口。

我使用了 Hibernate 4 的同时使用了 getHibernateTemplate().save(xxx) 所以报错找不出原因，可以的话将 Hibernate 3 中对应的 jar 包复制过来覆盖一下或者复制 jar 里面的方法，改写 Hibernate 4 的 jre，具体百度。
