基于springboot的外卖点餐

随着移动支付像微信和支付宝的普及，更多的人不愿意在口袋里放现金，导致本人捡钱的机会大大的降低，当前2021年随着美团和饿了么外卖平台的普及，更多的人不愿意花大量的时间在家自己煮饭吃，宁愿节约时间，甚至有的是不愿意洗碗，都在平台上点外卖，但是目前的两家外卖巨头，平台抽取商家的利润实在是收费太高，让大家很不情愿在上面入驻。

本设计是一个基于java采用springboot+mybatis框架开发的网上点餐项目，本在线点餐网站以IDEA+mysql为开发环境，HTML+CSS+JavaScript为页面编辑语言，springboot+mybatis为后台编辑语言来设计开发,开发一个在线点餐正是为了企业独立开发的目的。在国外 J2EE 已经成为开发电子商务平台的主流技术，本文研发的在线点餐系统使消费者进行购物时，不但菜品推荐更为符合食客的消费习惯，且菜品的质量安全以及消费者个人信息能够得到有效保障。

前台总体功能

首页功能：

1）展示菜单：按不同的分类（如主食，小炒，饮料）来显示一些菜品信息

2）新品上架：最新上架的菜品有“新”标识

3）推荐星值：1-5星

用户（顾客）功能：

1）用户注册：要求在客户端需要作一些格式验证，如果用户名已经存在，则要提示用户该账号已存在，注册失败！

2）用户登录：登录成功跳转到首页

A、用户在首页添加菜品到购物车

B、用户进入购物车还可以进行动态删减数量

C、用户提交订单，清空购物车

D、用户可以实时看到订单的状态（未接单、已接单（届时送达）、已完结）

E、用户可以查看并修改自己的信息（头像、密码、姓名、手机、地址）

登录设计

5.0.1 登录

配置springboot Security5，使用Security自带的登录请求，前端修改为自己设计的登录页面。springboot Security5实现接入数据库，托管账户。具体实现如下：

@Override //授权规则

protected void configure(HttpSecurity http) throws Exception {

http.authorizeRequests().antMatchers("/","/index","/main").permitAll()

.antMatchers("/userInfo","/insertUserInfo","/edUserInfo","/deleteUser/**").hasAnyRole("admin")

.antMatchers("/menuManage","/deleteOneMenu/**","/upLoadImg","/insertMenu","/updateMenu").hasAnyRole("admin")

.antMatchers("/insertType","/updateType","/deleteType").hasAnyRole("admin")

.antMatchers("/orderManage","/changeStatusToOne").hasAnyRole("admin")

.antMatchers("/myInfo","/updateMyImg","/updateMyInfo").hasAnyRole("admin","user")

.antMatchers("/shoppingCart","/shoppingCart-plus","/shoppingCart-minus","/addShoppingCart").hasAnyRole("user")

.antMatchers("/toOrder","/myOrder","/changeStatusToTwo").hasAnyRole("user");

http.formLogin().loginPage("/toLogin").usernameParameter("uUsername").passwordParameter("uPassword")

.loginProcessingUrl("/login") //表单提交的请求，可以不需要路由（走security的路由）

.failureUrl("/toLogin?error=true");

http.csrf().disable(); //取消ajax拦截（post），如果改为post/get则可能不会报错

http.logout().logoutSuccessUrl("/toLogin");

//解决中文乱码问题

CharacterEncodingFilter filter = new CharacterEncodingFilter();

filter.setEncoding("UTF-8"); filter.setForceEncoding(true);

http.addFilterBefore(filter, CsrfFilter.class);

//开启记住我功能

http.rememberMe().rememberMeParameter("remember");*/

}

userServiceImpl实现验证方法

@Override //验证规则

protected void configure(AuthenticationManagerBuilder auth) throws Exception {

auth.userDetailsService(tbUserService).passwordEncoder(new NoPasswordEncoder());

}

4.1.2 注册

判断前端传过来的字段，查询数据库中是否存在，如果不存在则完成插入，否则提示该账号已存在。

@PostMapping("/register")

public String register(String uUsername, String uPassword, String uRole,Model model){

List<TbUser> users = tbUserService.selectAllUser();

for (TbUser temp : users){ //验证成功，直接登录

if(uUsername.equals(temp.getUUsername())){

model.addAttribute("msg","刚刚：注册失败，该用户已存在！");

return "user/login";

}

TbUser user = new TbUser();

user.setUUsername(uUsername);

user.setUPassword(uPassword);

user.setURole(uRole);

tbUserService.insertUser(user);

model.addAttribute("msg","刚刚：注册成功，赶快登录进行登录吧~");

return "user/login";

}

4.2 首页展示

4.2.1 读取菜品数据

读取菜品数据表和菜品类型表，完成视图解析，返回到首页

@RequestMapping({"/main","/","/index"})

public String main(Model model,HttpSession session){

//用于封装整合后的对象的集合

List<MenuDetail> menus = new ArrayList<MenuDetail>();

List<MenuType> types = menuTypeService.selectAllType(); //查询出所有类型对象

//临时集合，用于存放需要移除的，0菜品的类型对象

List<MenuType> temp = new ArrayList<MenuType>();

//通过mt_id重新封装对象列表

for (MenuType type : types){

List<MenuDetail> menu = menuDetailService.selectByType(type.getMtId());

//如果当前分类没有菜品，则移除该分类，同时不添加

if (menu.size() == 0){

temp.add(type);

}

menus.addAll(menu);

}

//封装后的list

model.addAttribute("menus",menus);

//移除空的类型

for (MenuType t : temp){

types.remove(t);

}

model.addAttribute("types",types);

return "main";

}

4.3 消费者功能

4.3.1 加入购物车

通过Jquery获得遍历出来的菜品，经过ajax发送请求到后端完成菜品插入到购物车数据库表中。

function getDetail(a) {

let list = $(a).children('input'); //获得当前元素下的所有子input

if (list.length == 5){ //5个说明处于未登录状态

alert("请先登录，再订餐哦~");

}

if($(list[6]).val() == "ROLE_admin"){

alert("你就是老板啦，你不能下单哦~");

} else{

let mdName = $(list[0]).val();

let mdPrice = $(list[2]).val();

$('#tips-name').html("【名称】"+mdName);

$('#tips-price').html("【价格】"+mdPrice+'元');

/*发起请求*/

let postData = {};

postData['scName'] = mdName;

postData['scAmount'] = 1;

postData['scPrice'] = mdPrice;

postData['scImg'] = $(list[3]).val();

postData['mdId'] = $(list[4]).val();

postData['uId'] = $(list[5]).val();

$.ajax({

url: "/addShoppingCart",

type: 'POST',

data: postData,

success: function (arg) {

console.log(arg);

// window.location.reload();

}

})

}

/*去我的购物车页面*/

@RequestMapping("/shoppingCart")

public String shoppingCart(Model model,int uId){

//查询购物车的商品

List<ShoppingCart> products = shoppingCartService.selectAllByUId(uId);

int total = 0;

for (ShoppingCart cart : products){

total += cart.getScPrice()*cart.getScAmount();

}

model.addAttribute("products",products);

model.addAttribute("total",total);

if(total>=30 && total<50){

model.addAttribute("paytotal",total-2);

}

if(total>=50 && total<80){

model.addAttribute("paytotal",total-4);

}

if(total>=80){

model.addAttribute("paytotal",total-10);

}

return "user/shoppingCart";

}

4.3.2 管理购物车

动态删减数量

@RequestMapping("/shoppingCart-plus")

public String shoppingCartPlus(int uId,int mdId){

//把数量+1
