我的SSH框架实例（附源码）

2021-11-02 23:16:18

　　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.

　　链接：https://pan.baidu.com/s/16i5dDIoDi4gOMsZfPvz6eg
　　提取码：pjqa

　　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
