Oracel的期末作業，寫一個簡單的web頁面連接oracle數據庫實現增刪改查
完整源碼鏈接：https://pan.baidu.com/s/1f2TfFt-5NFNspYM43J2muA
提取碼: mfdh
開發環境：
編譯器：Eclipse
數據庫：Oracle
數據庫管理器：Navicat
效果展示：
文件目錄：
功能：
添加：添加新的學生信息，包括學號、姓名、性別、電話
刪除：刪除已有學生信息
更新：更改已有學生信息，包括姓名、性別、電話
查找：通過關鍵字查找相關學生信息
數據庫設計：
學生表Student
| 列名 | 類型 | 約束 | 備註 |
|---|---|---|---|
| id | NUMBER(38,0) | 非空、主鍵 | 學號 |
| name | NVARCHAR2(20) | 非空 | 姓名 |
| sex | NVARCHAR2(2) | 非空 | 性別 |
| phone | NVARCHAR2(25) | 非空 | 電話 |
