mall

mall is a complete online-shopping platform written in Java. It comes in two halves: a customer-facing storefront and an admin back office for the people running the shop. The storefront covers what shoppers expect — a homepage, product recommendations, search, product pages, a cart, the checkout and order flow, a member account area, customer service, and a help center. The admin side handles the work behind the counter: managing products, processing orders, looking after member accounts, running promotions, day-to-day operations, content, statistical reports, finances, user permissions, and settings. Under the hood the back end is built with Spring Boot and MyBatis, the standard Java stack for this kind of web application. Spring Boot runs the web server, MyBatis talks to the database, and Spring Security handles login and access rules. Around them sit the supporting pieces every busy shop needs: MySQL as the main database, Redis for caching, Elasticsearch for product search, MongoDB for document storage, RabbitMQ for passing messages between parts of the system, and the ELK stack for collecting and viewing logs. Everything is packaged into Docker containers so the whole stack can be deployed as a unit. The storefront and admin UI are separate Vue projects that talk to these back-end services, with a mobile version built on uni-app. Someone would pick this up to learn how a real-world online-shopping system is put together, to use as a template for their own shop, or as a teaching example for Spring Boot. A sister project, mall-swarm, rebuilds the same system on Spring Cloud Alibaba as a microservices version.
