视频成果
SSM框架基于JavaWeb在线投票系统的设计与实现源码

零碎阐明
依据系统分析，将在线投票管理系统分为前台功能模块和后盾功能模块。其中零碎前台性能实现用户注册、用户登录、浏览、投票、投票核心和投票历史等性能。零碎前台性能如图5-2所示：

图5-2 零碎前台功能模块结构图

用户注册：用户填写用户名、明码和性别，点击注册按钮进行注册。

用户登录：用户填写曾经注册的用户名和明码，点击登录按钮进行登录。

浏览：用户能够浏览在线投票管理系统中公共凋谢内容。

投票：用户抉择本人须要的投票，针对主题，勾选选项，进行投票操作。投票形式反对单选只能投一次、单选一天只能投一次、多选只能投一次、多选一天只能投一次等四种形式。

投票核心：在线投票管理系统展现所有投票主题供用户抉择。

投票历史：存储用户曾经投票的历史内容，用户登陆前方可查看。

零碎后盾性能实现以下性能，投票信息管理、具体投票查看、用户信息管理、投票信息统计和管理员登录等性能。零碎后盾性能如图5-3所示：

图5-3 零碎后盾功能模块结构图

投票信息管理：管理员进行投票信息管理，能够治理投票主题和投票选项。针对投票主题，能够增加投票主题（须要填写主题名称、主题类型、开始工夫、完结工夫和主题简介）、查看主题、批改主题和删除主题；针对投票选项治理，能够增加选项（须要填写选项名称和抉择所属主题）、查看选项、批改选项和删除选项。

具体投票查看：管理员查看投票的详细信息，以列表模式显示，每条投票详细信息包含：投票ID、用户名、投票主题、投票选项、总投票数和投票工夫等信息。

用户信息管理：管理员进行用户信息管理，能够增加用户（须要填写用户名、明码、性别和状态）、查看用户信息、批改用户信息和删除用户。

投票信息统计：管理员进行投票信息统计，默认显示所有的投票主题统计，输出搜寻主题名称后显示单个主题的投票统计。

管理员登录：管理员输出用户名、明码和验证码，点击登录按钮，进行登录操作。

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

后端：Spring+SpringMVC+Mybatis
前端：JSP+CSS+JavaScript+jQuery

应用阐明

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；
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；
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;
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:

package com.sxl.controller.admin;

import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

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);    return "/admin/tj/tj1";}@RequestMapping(value = "/password")public String password(Model model, HttpServletRequest request)throws Exception {    return "/admin/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);    }}
