hibernate4+spring3+struts2搭建框架实例

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"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

  </context-param>
  	<!-- contentloader -->

  </filter>

  <filter-mapping>

		<dispatcher>FORWARD</dispatcher>
	</filter-mapping>

	<filter-mapping>
		<filter-name>struts-cleanup</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3.applicationContex.xml文件配置，sessionFactory的配置类是：org.springframework.orm.hibernate4.LocalSessionFactoryBean
