WeChat Order System Design And Implementation

With the popularity of the internet and smart phones,more and more scenes are moved from the offline to online,we can call the car,we can order,we can do payment through the phone.But making order in a restaurant is still mainly through the paper menu now,menu paper is not convenient to update,ordering efficiency is also low,the waiter is in need to wait for making order,this costs high for the restaurant,and not environmental protection,so electronic menu is imperative.In the mobile internet time,WeChat is an APP which almost everyone to install and use,with two-dimensional code as the entrance,with the official account as the carrier,and with the popularity of mobile payment,ordering through WeChat official account is a way can improve the order efficiency,reduce the cost of the restaurant.This paper mainly studies the analysis,design and implementation of WeChat order system,from the project design,system analysis design and database system design,to establish a scalable,highly available,distributed,safe and convenient maintenance system.In the system,use Ice(Internet Communications Engine)services distributed RPC(Remote Procedure Call)framework,API(Application Process Interface)is using the Spring framework to develop,specific use Spring MVC(Model-View-Controller)framework and Spring Boot framework to simplify the development,In storage,database use MySQL and cache service use Redis,ORM(Object Relational Mapping)framework use Mybatis,use Nginx and Tomcat to deploy the system,use AliCloud and Linux CentOS,use Facebook React Native framework and Android to develop APP client,the front interface using Node layer call interface,to transmit data through the JSON(JavaScript Object Notation)data format,interface development using HTML5,realize the separation of frontend and backend;system analysis and design,focusing on the description of the functional modules of the system,including the completion of the user module,order module,WeChat module,payment module and other modules.
