SSM框架搭建簡單實例 - 搭建步驟
需求分析：
實現用戶表信息的增刪改查
1. 開發環境
- 環境 ： JDK 1.8
- 軟件 ： myeclipse
- 數據庫 ： MySql
2. 創建數據庫
- 數據庫名稱：ssm
- 字符集：UTF-8
- 表 ： user
3. 工程搭建
- 工程使用Springmvc、spring、mybatis框架整合完成。
- 項目完整目錄截圖
4. 創建web工程
- 準備需要的jar包
- spring（包括springmvc）
- mybatis
- mybatis-spring整合包
- 數據庫驅動
- 第三方連接池。
- Json依賴包（springmvc 自帶，可不加）
-
web.xml 文件
需要配置的有 ： Spring監聽器， SpringMVC 核心前端控制器， 字符集過濾器
