Mall4cloud is a microservices e-commerce platform built on Spring Boot 4 and Spring Cloud that implements a B2B2C marketplace architecture. The project addresses the need for a complete, production-ready multi-tenant shopping system by combining distributed transaction management through Seata, service discovery via Nacos, caching with Redis, message queuing through RocketMQ, search capabilities with Elasticsearch, and file storage using MinIO. It provides separate interfaces for platform administrators, merchants, and end users, along with a complete order processing workflow.
The system solves the complexity of building scalable multi-merchant e-commerce platforms by offering a reference implementation that demonstrates how to coordinate multiple microservices in a real-world commerce scenario. The architecture uses Canal for data synchronization and includes modules for platform management, shop management, product management, order management, specifications, permissions, and resources. This approach allows developers to study microservices patterns in an e-commerce context while having a foundation they can evaluate for multi-merchant source code assessment or adapt for enterprise deployments.
Organizations considering adoption should note that the open-source version targets B2B2C marketplace scenarios and is suitable for teams learning microservices architecture, evaluating multi-merchant commerce systems, or planning secondary development of enterprise shopping platforms. The project maintains both an open-source version under AGPLv3 and commercial licensing options. Commercial versions extend support to additional business models including B2C, S2B2C, B2B2B, SaaS, multi-tenant, and cross-border scenarios, with source code delivery and permanent licensing available through commercial agreements.
The project maintains active development with regular updates to its technology stack, having upgraded to Spring Boot 4, Spring Cloud, and Vue3 on its main branch. Documentation is provided in the repository's doc directory alongside quick-start guidance. The codebase reflects ongoing maintenance of dependencies and framework compatibility, with specific versions tracked in backend pom.xml and frontend package.json files rather than hardcoded in documentation.
