SSM框架的師范學院教務信息查詢系統(tǒng)的設計與實現(xiàn)源碼

系統(tǒng)說明
根據上文中對用戶需求的一系列綜合細致的分析，針對本文基于Java Web的教務信息查詢系統(tǒng)，得到模塊結構圖，如圖所示：
?
?
本系統(tǒng)中老師模塊實現(xiàn)的功能主要有個人信息的維護即對用戶資料的增刪改查，和成績的錄入和查詢；學生模塊實現(xiàn)的功能有個人信息的維護還有成績的查詢；負責后臺運營協(xié)調的管理員則可以進行對所有用戶的信息維護，以及綜合管理課程班級信息和學生科目成績。
環(huán)境需要
1.運行環(huán)境：最好是java jdk 1.8，我們在這個平臺上運行的。其他版本理論上也可以。
2.IDE環(huán)境：IDEA，Eclipse,Myeclipse都可以。推薦IDEA;
3.tomcat環(huán)境：Tomcat 7.x,8.x,9.x版本均可
4.硬件環(huán)境：windows 7/8/10 1G內存以上；或者 Mac OS；?
5.數據庫：MySql 5.7版本；
6.是否Maven項目：否；
技術棧
1. 后端：Spring+SpringMVC+Mybatis
2. 前端：JSP+CSS+JavaScript+jQuery
使用說明
1. 使用Navicat或者其它工具，在mysql中創(chuàng)建對應名稱的數據庫，并導入項目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse導入項目，Eclipse/MyEclipse導入時，若為maven項目請選擇maven;
若為maven項目，導入成功后請執(zhí)行maven clean;maven install命令，然后運行；
3. 將項目中springmvc-servlet.xml配置文件中的數據庫配置改為自己的配置;
4. 運行項目，在瀏覽器中輸入http://localhost:8080/ 登錄
