Project Introduction

This project is a high-performance review and coupon system inspired by the "HeiMa DianPing" course. It is built with Spring Boot, MyBatis-Plus, and Redis, and demonstrates practical solutions for high-concurrency scenarios such as distributed locking, Redis Streams, cache penetration/breakdown/avalanche, and more. The system includes core features like user login, merchant reviews, following, flash sale coupons, blog publishing, and commenting. The frontend resources are located in src/main/resources/nginx-1.18.0.

This project is suitable for learning enterprise-level backend development and hands-on practice with Redis and distributed systems.

Features

• User Authentication: Secure login and registration with session/token management.
• Merchant Reviews: Users can post, view, and interact with shop reviews.
• Follow System: Users can follow/unfollow others and view followed users’ activities.
• Flash Sale Coupons: High-concurrency voucher (seckill) system using Redis Streams and distributed locks.
• Blog System: Users can publish blogs, comment, and interact with posts.
• Commenting: Nested comment support for blogs and shops.
• High-Concurrency Solutions: Implements distributed locking, cache strategies (penetration, breakdown, avalanche), and Redis Stream for order processing.
• Frontend Resources: Located in src/main/resources/nginx-1.18.0.

Technology Stack

• Backend: Java, Spring Boot, MyBatis-Plus
• Database: MySQL
• Cache & Messaging: Redis (including Streams, distributed locks, caching)
• Frontend: Static resources (HTML/CSS/JS) in the nginx-1.18.0 directory
• Build Tool: Maven

Project Structure

• src/main/java/com/hmdp/
  • controller/ — RESTful API controllers
  • service/ — Business logic and interfaces
  • entity/ — Data models/entities
  • mapper/ — MyBatis-Plus mappers for database access
  • utils/ — Utility classes (e.g., cache client, password encoder)
  • config/ — Spring and MyBatis configuration
• src/main/resources/
  • application.yaml — Main configuration file
  • mapper/ — MyBatis XML mapping files
  • nginx-1.18.0/ — Frontend static resources

Getting Started

1. Clone the repository:

   git clone https://github.com/cs001020/hmdp.git

2. Switch to the initial branch for hands-on practice:

   git checkout init

3. Configure your database and Redis in application.yaml.
4. Start the backend application:
   • Use your IDE or run with Maven:
     mvn spring-boot:run
5. Serve the frontend resources using nginx or your preferred static server.

Notes

• For high-concurrency features (like seckill), ensure Redis is running and properly configured.

Java后端实现简历描述

Java后端开发项目经验 —— 高性能点评与优惠券系统

项目简介： 独立开发高并发点评与优惠券系统，采用Spring Boot、MyBatis-Plus、Redis等主流技术，支持用户登录、商户点评、关注、秒杀优惠券、博客发布与评论等功能，前后端分离，具备企业级高并发处理能力。

核心职责与技术亮点：

• 负责系统整体后端架构设计与核心功能开发，采用分层架构（Controller-Service-Mapper），结构清晰，易于维护。
• 实现用户注册、登录、会话管理，用户信息高效缓存于Redis，提升系统响应速度。
• 设计并实现关注系统，关注关系存储于Redis集合，支持高效的共同关注查询。
• 优化商户点评、博客发布、评论等社交功能，支持点赞、评论等互动。
• 设计并实现高并发秒杀优惠券模块，利用Redis Stream和分布式锁，保障数据一致性与高性能。
• 深入解决缓存穿透、击穿、雪崩等问题，封装CacheClient工具类，提升系统稳定性。
• 使用MyBatis-Plus简化数据库操作，提升开发效率。
• 负责系统配置、数据库设计与性能调优，保障系统高可用与可扩展性。
