我的想法：
Hibernate：DaoImpl類繼承HibernateDaoSupport，使用getHibernateTemplate()或者Session操作數據。
Spring：加進去什麼都不干，就是使用C3P0。
Servlet：控制等等。
幫忙看看我的applicationContext.xml對不對：

目錄結構：

最佳回答：

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

hibernate 4 中沒有 HibernateDaoSupport，包括數據訪問都不需要 hibernatetemplate，必須改寫 dao，直接使用 hibernate 的 session 和 query 接口。

我使用了 Hibernate 4 的同時使用了 getHibernateTemplate().save(xxx) 所以報錯找不出原因，可以的話將 Hibernate 3 中對應的 jar 包復制過來覆蓋一下或者復制 jar 裡面的方法，改寫 Hibernate 4 的 jre，具體百度。
