Microservice E-commerce Platform - SpringCloud Alibaba Stack (Nacos/Gateway/Sentinel) + MyBatis-Plus + Feign Remote Calls.

Project Overview

Complete practice from monolithic to microservice architecture, covering enterprise middleware integration and distributed solutions. The project benchmarks against mid-senior Java backend engineer core competency models.

Technical Highlights

1. Distributed Architecture

Microservice Splitting: Independent services by business domain
Service Governance: Nacos discovery + Gateway routing
Distributed Transactions: Seata AT mode for cross-service consistency

2. Deep Middleware Integration

Redis: Cache + Distributed Lock + Session Management
Elasticsearch: Full-text Search + IK Analyzer
RocketMQ: Async Messaging + Transaction Messages
Sentinel: Rate Limiting + Circuit Breaking

3. High-Concurrency Seckill

Redis pre-deduction + Redisson reentrant lock
RocketMQ async persistence prevents overselling
Sentinel rate limiting protects system stability

4. Engineering Practices

Docker containerization
Gateway unified authentication
Nacos configuration center

Project Results

Architecture: 11 microservices designed and governed
Middleware: 11 enterprise middlewares integrated
Performance: 10k+ concurrent stress testing passed
