基于Struts和hibernate框架的学生信息管理系统
准备工作：
1、新建工程StudentMessageManagerSystem:File→New→WebProject→ProjectName→Finish
2、导入数据库驱动文件WebRoot下的WEB-INF下的lib，右键Import→FileSystem，然后选择驱动文件。
3、导入MyEclipse自带的Struts：工程名右键→MyEclipse→Add Struts Capabilities→Struts specification→Struts 2.1→Finish
4、导入MyEclipse自带的Hibernate架包：工程名右键→MyEclipse→Add Hibernate Capabilities→Hibernate specification→hibernate 4.1→Next→Next→
jdbc:mysql://localhost:3306/test
com.mysql.jdbc.Driver
root
0514
第一个test为数据库名；0514为我的数据库密码。
（这个配置在hibernate.cfg.xml中，后面还需要继续配置，我下面会贴出）
5、工程结构图如下：
