1.所需要的JAR包
2.web.xml配置文件，这个和平时的配置是一样的
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"

</filter-mapping> <welcome-file-list>

</welcome-file-list>
</web-app>
3.applicationContex.xml文件配置，sessionFactory的配置类是：org.springframework.orm.hibernate4.LocalSessionFactoryBean
<?xml version="1.0" encoding="UTF-8"?>
