我的SSH框架实例（附源码），
整理一下从前写的SSH框架的例子，供新人学习，使用到了注解的方式.
源码和数据库文件在百度网盘：http://pan.baidu.com/s/1hsH3Hh6
提取码：br27
对新同学的建议：最好的学习方法是自己手动敲一遍，切不可看过别人写的，就觉得自己会做了
使用方式
1、首先将项目mywork3.rar解压，导入到myeclipse中，注意修改applicationContext.xml 中用户名、密码，jdk使用1.6以上的就可以。
解压后其目录结构如下：
2、在mysql中新建数据库mydb
3、导入SQL文件 user.sql
4、启动项目，输入http://localhost:8080/mywork3/ 即可打开页面
