Java implementation of restaurant ordering system

1. Background of ordering management system

With the development of science and technology, going to a restaurant for a meal and checking out are all done online.
a. Compared with the current systems, this system has table management, cuisine management, dish name management, order management, order details and other functions.
b. Compared with the existing system, this system is a B/S structure. Generally, the ordering system is a C/S structure, which is not as good as the B/S structure in performance. Moreover, the C/S interface needs to be installed with a client, which is under great pressure. My system only needs a computer or a mobile phone with a browser, and can order meals in the same LAN.
c. In terms of architecture, our system is a distributed architecture, and the traditional ordering system is not reasonable.

2. Technical framework of order management system

Main technology
Spring,SpringMVC,Mybatis
JSP,JSTL,jQuery,HTML,CSS,JS
Mysql
bootstrap
Development tools and environment

4. Database design

CREATE TABLE `dinnertable` (
  `id` int(11) NOT NULL AUTO_INCREMENT,--table id
  `tableName` varchar(20) DEFAULT NULL, -- Table name
  `tableStatus` int(11) DEFAULT '0',   -- Table status 0 indicates idle status 1 indicates reserved status

)
-- Sichuan cuisine, Hunan cuisine, etc

  PRIMARY KEY (`id`),
  KEY `order_table_id` (`table_id`),
  CONSTRAINT `order_table_id` FOREIGN KEY (`table_id`) REFERENCES `dinnertable` (`id`)
) 

-- Order Details 
CREATE TABLE `orderdetail` (
  `id` int(11) NOT NULL AUTO_INCREMENT,       -- order details id
  `orderId` int(11) DEFAULT NULL,             -- Subordinate orders id

  CONSTRAINT `orderDetail_food_id` FOREIGN KEY (`food_id`) REFERENCES `food` (`id`),
  CONSTRAINT `orderDetail_order_id` FOREIGN KEY (`orderId`) REFERENCES `orders` (`id`)
)

-- Administrator table
CREATE TABLE `admin` (
  `id` varchar(20) NOT NULL,                     -- Administrators id
  `name` varchar(20) DEFAULT NULL,               -- Administrator name
  `password` varchar(32) DEFAULT NULL,           -- Administrator password
