基于 Python 学生问题管理系统设计与实现

零碎阐明
学生问题管理系统的开发是否可行,能够从以下几个方面进行全面的剖析。[15]

3.1.1 技术可行性
学生问题管理系统次要应用 python 技术、基于 B / S 构造,Mysql 数据库,利用程序开发须要一个残缺的性能,应用简略的特点,残缺的数据,建设数据库的平安与稳固。所以该零碎又较高开发需要性以及开发时候也须要肯定的开发常识,零碎的开发是可行的。

3.1.2 操作可行性
学生问题管理系统登录界面简略易操作,采纳常见的界面窗口登录界面,通过电脑拜访操作,用户能够执行,只有平时用电脑拜访操作。零碎应用 python 语言的倒退的倒退,基于 B / S 构造,开发环境使零碎更加完满。该零碎操作不便的特点,易于治理和良好的交互性,操作非常简单,是能够反对本开发的。

3.1.3 经济可行性
学生问题管理系统是基于 B / S 模式,零碎的开发原本就是如何省钱如何开发,因为零碎的规模不大,所以开发人员也只有我一个人,开发过程中应用的技术在校园所学的常识和联合本人在家网络上的学习常识,技术方面是不会存在太多难度的,并且没有额定的开发人员,也不会有别的开销。而且开发技术大多都是收费的,网络上很多开源我的项目和框架能够作为参考,所以该我的项目是具备经济可行性的。

3.1.4 法律可行性
学生问题管理系统是数据管理系统类设计,法律上的可行性次要取决于新制度的倒退是否会导致社会或政治上的侵权,以及它是否守法问题,零碎开发过程中的所有技术材料都是非法的。在开发过程中没有知识产权问题。没有进犯版权,因为它没有复制其余零碎。在开发过程中不承当任何法律责任。3.2 零碎流程剖析

环境须要
1. 运行环境:最好是 java jdk 1.8,咱们在这个平台上运行的。其余版本实践上也能够。
2.IDE 环境:IDEA,Eclipse,Myeclipse 都能够。举荐 IDEA;
3.tomcat 环境:Tomcat 7.x,8.x,9.x 版本均可
4. 硬件环境:windows 7/8/10 1G 内存以上;或者 Mac OS;
5. 数据库:MySql 5.7 版本;
6. 是否 Maven 我的项目:否;

技术栈

  1. 后端:Spring+SpringMVC+Mybatis
  2. 前端:JSP+CSS+JavaScript+jQuery

应用阐明

  1. 应用 Navicat 或者其它工具,在 mysql 中创立对应名称的数据库,并导入我的项目的 sql 文件;
  2. 应用 IDEA/Eclipse/MyEclipse 导入我的项目,Eclipse/MyEclipse 导入时,若为 maven 我的项目请抉择 maven;
    若为 maven 我的项目,导入胜利后请执行 maven clean;maven install 命令,而后运行;
  3. 将我的项目中 springmvc-servlet.xml 配置文件中的数据库配置改为本人的配置;
  4. 运行我的项目,在浏览器中输出 http://localhost:8080/ 登录

管理员管理控制层:

import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;

import com.sxl.controller.MyController;

@Controller(“adminController”)
@RequestMapping(value = “/admin”)
public class AdminController extends MyController {



@RequestMapping(value = "/index")
public String frame(Model model, HttpServletRequest request)throws Exception {return "/admin/index";}

@RequestMapping(value = "/main")
public String main(Model model, HttpServletRequest request)throws Exception {return "/admin/main";}

@RequestMapping(value = "/tj1")
public String tj1(Model model, HttpServletRequest request)throws Exception {String sql="select DATE_FORMAT(insertDate,'%Y-%m-%d') dates,sum(allPrice) price from t_order order by DATE_FORMAT(insertDate,'%Y-%m-%d')  desc";
    List<Map> list = db.queryForList(sql);
    model.addAttribute("list", list);
    System.out.println(list);

}


@RequestMapping(value = "/password")

@RequestMapping(value = "/changePassword")
public ResponseEntity<String> loginSave(Model model,HttpServletRequest request,String oldPassword,String newPassword) throws Exception {Map admin = getAdmin(request);
    if(oldPassword.equals(admin.get("password").toString())){
        String sql="update t_admin set password=? where id=?";
        db.update(sql, new Object[]{newPassword,admin.get("id")});
        return renderData(true,"1",null);
    }else{return renderData(false,"1",null);
    }
}

}
