12306 is a distributed railway ticketing system project designed to teach high-concurrency and microservices architecture through a realistic e-commerce scenario.
The project addresses the challenge of learning distributed system design by providing a full-stack implementation of a ticket booking platform with member management, ticketing, orders, and payment services. It demonstrates core distributed concepts including caching, message queues, database sharding, and design patterns. The system is built on modern technology: Java 17, Spring Boot 3, Spring Cloud Alibaba, Vue 3, alongside infrastructure components like Elasticsearch, Redis, RocketMQ, Nacos, Sentinel, and ShardingSphere.
The project offers two deployment models to suit different learning goals. The Spring Boot aggregated service version prioritizes testing and deployment, allowing direct startup of a unified service and gateway. The Spring Cloud microservices version emphasizes learning microservices design patterns by running separate payment, order, user, ticketing, and gateway services independently. This dual approach makes it suitable for students preparing for employment interviews who want to understand both monolithic and distributed architectures, or for those specifically interested in high-concurrency system design. The README positions this as an official recommendation for campus recruitment preparation.
The project maintains active engagement with its learning community through a public communication channel and resource sharing mechanism. Development focuses on keeping the technology stack current with the latest Java and Spring ecosystem releases. The codebase is structured to demonstrate production-grade patterns and architectural decisions relevant to modern enterprise systems.
