What it is

mall is a complete e-commerce system built on Spring Boot and MyBatis, distributed as a Java project under the Apache-2.0 license. It ships two applications in one repository: a storefront system for shoppers and an administrative back office for operators. The storefront covers the home portal, product recommendation, product search, product display, shopping cart, order flow, member center, customer service, and help center. The back office covers product management, order management, member management, promotion management, operations management, content management, statistics reports, finance management, permission management, and settings. Deployment is containerized with Docker. The project lives in the Java and Spring ecosystem, and its topic list places it alongside MySQL, Redis, MongoDB, Elasticsearch, RabbitMQ, and the ELK stack.

The concrete problem it solves is the gap between a demo storefront and a working commerce stack. A team that needs catalog, cart, checkout, membership, promotions, and reporting normally assembles those pieces from scratch, wiring an ORM, an authorization framework, a search engine, a message broker, a cache, and object storage by hand. mall provides those layers already integrated: MyBatis with MyBatisGenerator for data access, Spring Security with JWT for authentication and authorization, Elasticsearch for the search subsystem, RabbitMQ for messaging, Redis for in-memory storage, and MongoDB as a NoSQL store. The repository is split into mall-common, mall-mbg, mall-security, mall-admin, mall-search, mall-portal, and mall-demo, so the administrative API, the storefront API, and the search service can be read and deployed separately.

Key capabilities

• Storefront API in mall-portal covering home portal, product recommendation, product search, product display, cart, order flow, member center, customer service, and help center.
• Administrative API in mall-admin covering product, order, member, promotion, operations, content, statistics report, finance, permission, and settings management.
• Dedicated search service in mall-search built on Elasticsearch.
• Authentication and authorization through Spring Security with JWT login support, packaged as the reusable mall-security module.
• Data layer generated by MyBatisGenerator and exposed through MyBatis, with Druid as the connection pool and PageHelper for physical pagination.
• Object storage support for both Aliyun OSS and MinIO.
• Log collection and visualization through LogStash and Kibana, with Nginx serving static resources.

Who uses it and how

• Teams evaluating a full commerce stack can open the hosted admin demo and the hosted storefront demo before installing anything.
• Developers learning Spring Boot, Spring Security, and MyBatis use the project as a reference implementation, following the written tutorial and the video tutorial published alongside the code.
• Operators running a self-hosted shop deploy the backend with Docker and pair it with the separate mall-admin-web
