    @After
    public void tearDown() throws Exception {

            sessionFactory.close();
        }
    }

    @Test
    public void test() {
        Session session=sessionFactory.openSession();
        session.beginTransaction();
        Student student=new Student("fuwh",22);
        session.save(student);
        session.getTransaction().commit();

　　测试完三个框架各自的必须包无问题后，那么现在就开始用Spring来整合Struts2和Hibernate。

　　Spring在整合Strut2的时候，需要加入Struts提供的一个struts2-spring-plugin-2.5.10.jar开发包。

　　然后在web.xml文件中，加入Spring的监听器，默认会让Spring来创建所有的Struts2对象，但是如果Spring创建不成功。

　　则struts2会自己创建。

　　Spring在整合Hibernate的时候，则需要加入一些数据库访问的包，本例中还使用了dbcp的连接池。

　　spring-orm-4.3.6.RELEASE.jar

　　spring-jdbc-4.3.6.RELEASE.jar

　　commons-dbcp2-2.1.1.jar

　　commons-pool2-2.4.2.jar

　　如果还要使用切面，事务等其他功能则另外添加jar包。

这样就基本上整合好了。

当然数据源并不是必须的，也可以将Spring的配置文件中的数据源删掉，然后在hibernate中配置数据库连接属性。
