基於Spring MVC + Spring + MyBatis的【學生管理管理系統】


資源下載:https://download.csdn.net/download/weixin_44893902/45602690

練習點設計:模糊查詢、刪除、新增

一、語言和環境

  1. 實現語言:JAVA語言。
  2. 環境要求:MyEclipse/Eclipse + Tomcat + MySql。
  3. 使用技術:Jsp+Servlet+JavaBeanSpringMVC + Spring + Mybatis

二、實現功能

隨着“朝陽會計培訓學院”人數的增多,現需要制作學生管理系統,主要功能如下:

1.首頁默認顯示所有學員信息,如圖所示。
圖 1 首頁顯示所有信息
2.鼠標懸停某行數據時,該數據顯示橙色,如圖所示。
圖 2 鼠標懸停效果
3.用戶輸入學生姓名時,點擊搜索,則完成模糊查詢,顯示查詢結果,如圖 3 所示。
圖 3 模糊查詢結果
4.用戶點擊刪除,則彈出提示框,用戶點擊確定后,刪除選中數據並顯示最新數據,如圖 4 和圖 5 所示。
圖 6 增加數據 圖 7 展示最新數據
在這里插入圖片描述
5. 用戶點擊“錄入”鏈接,則打開新增頁面,填寫完相關信息后,如果不想錄入點擊“取消”回到主頁,錄入則點擊錄入按鈕,增加學員信息數據到數據庫,且頁面跳轉到列表頁面展示最新數據,.

三、 數據庫設計

  1. 創建數據庫(student_db)。
  2. 創建數據表(student),結構如下。

四、推薦實現步驟

1.SSM 版本的實現步驟如下:
(1)創建數據庫和數據表,添加測試數據(至少添加 5 條測試數據)。
(2)創建 Web 工程並創建各個包,導入工程所需的 jar 文件。
(3)添加相關 SSM 框架支持。
(4)配置項目所需要的各種配置文件(mybatis 配置文件、spring 配置文件、springMVC 配置文件)。
(5)創建實體類。
(6)創建 MyBatis 操作數據庫所需的 Mapper 接口及其 Xml 映射數據庫操作語句文件。 (7)創建業務邏輯相應的接口及其實現類,實現相應的業務,並在類中加入對 DAO/Mapper 的引用和注入。
(8)創建 Controller 控制器類,在 Controller 中添加對業務邏輯類的引用和注入,並配置 springMVC 配置文件。
(9)創建相關的操作頁面,並使用 CSS 對頁面進行美化。
(10)實現頁面的各項操作功能,並在相關地方進行驗證,操作要人性化。
(11)調試運行成功后導出相關的數據庫文件並提交。

2.JSP 版本的實現步驟如下:
(1)按以上數據庫要求建庫、建表,並添加測試數據。
(2)創建 Web 工程並創建各個包,導入工程所需的 jar 文件。
(3)創建實體類。
(4)創建 Servlet 獲取用戶不同的請求,並將這些請求轉發至業務處理層相應的業務方法。
(5)創建業務處理層,在其中定義業務方法實現系統需求,在這些業務方法中需要執行 DAO 方法。
(6)創建 BaseDAO 工具類,使用 JDBC 完成數據表數據的查詢、刪除和添加。
(7)編寫 JSP 頁面,展示數據的查詢結果。

五、實現代碼
