SSM整合 记账簿项目

建议！！！先下载源码运行成功后理解每一部分都做了什么样的事情后在开发。

学完ssm框架后做了一个maven项目，关于一个简单的记账簿，这里主要使用到 ssm框架+maven项目（包括登录，注册，记账（就是添加），删除记账目录，修改记账目录）

源码

github下载地址

功能截图：

下面我详细向大家描述一下这个项目的总过程：

1. 环境搭建 ，首先创建一个maven项目，创建模式百度参考一下我就不具体说了，另外这里用到了mybatis的自动生成代码，如果不懂请参考：
   学习连接：http://how2j.cn/k/mybatis/mybatis-generator/1376.html#nowhere
2. 建立数据库
   2.1创建名称为 cashbook的mysql数据库，下面是sql执行代码，我会把cashbook.sql文件上传。
   category是记账的类别表格，
   date是记账的时间表
   img忽视吧 没什么用
   orderitem是记录的账单
   totalitem是每个用户记录的总条数
   user是用户表

4.maven整合SSm重要的配置文件：
