登录和注册(jsp+servlet+JavaBean)
一：创建web项目导入struts2和hibernate的jar包，jar包放入WEB-INF下lib目录里
struts2的jar包六个：struts2-core-2.1.8.1.jar，commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar，freemarker-2.3.15.jar
ognl-2.7.3.jar，xwork-core-2.1.6.jar
hibernate的jar包十八个：antlr-2.7.6.jar，asm.jar ，asm-attrs.jar，
c3p0-0.9.1.jar，cglib-2.1.3.jar ，hibernate3.jar
commons-collections-2.1.1.jar ，jaas.jar
commons-logging-1.0.4.jar，dom4j-1.6.1.jar
ehcache-1.2.3.jar，javassist.jar，jaxen-1.1-beta-7.jar
jdbc2_0-stdext.jar，jta.jar ，log4j-1.2.11.jar，
xerces-2.6.2.jar ，xml-apis.jar
二：model层
Student.java
//Student.hbm.xml 此映射文件要与Student.java类放在一起，放在model层下 //MyClass.java //MyClass.hbm.xml 此xml配置同上 以下类放置组件包内 //BaseAction.java //HibernateUtil.java //LazyFilter.java(过滤器) //Page.java // dao层：StudentDao.java //service层：StudentService.java //实现service层：StudentServiceImpl.java // action层：StudentAction.java //struts.xml配置 此xml文件放到web项目src跟目录下 //hibernate.cfg.xml 此xml文件放到web项目src跟目录下 //上传的文件Book1.csv 用excel文档制作，保存的扩展名为.csv文件 //web.xml //index.jsp //show.jsp上传页面 //success.jsp上传成功后用分页显示 //error.jsp上传失败显示页面 以上三个JSP页面放到WEB-INF/page页面下 数据库test，表名student，myclass 三：大致的项目图 package com.wdpc.hibernate.model;
