The system +implements distributed architecture with anti-overselling mechanisms, rate limiting, and distributed locking using Redis +and Lua scripts. + +**Project Completion**: 90% + +## Core Architecture + +### Technology Stack + +- **Backend**: Spring Boot 2.7.6, Java 1.8 +- **Database**: MySQL with JPA/Hibernate +- **Cache**: Redis Cluster with Redisson +- **Frontend**: JSP + JSTL + Bootstrap 5 + jQuery +- **Build Tool**: Maven +- **API Documentation**: Knife4j (Swagger) + +### Key Components + +- **Controllers**: Handle HTTP requests for different modules (flash sales, cart, orders, admin) +- **Services**: Business logic layer with Redis-based caching and distributed operations +- **Repositories**: JPA data access layer for MySQL operations +- **DTOs**: Data transfer objects for API communication +- **Entities**: JPA entities mapping to database tables + +### Redis Integration + +- **Cluster Configuration**: Multi-node Redis cluster setup via RedissonConfig +- **Data Types**: String (locks, sessions), Hash (user/product info, cart), List (order queues), Set (successful users), + ZSet (rankings) +- **Lua Scripts**: Atomic operations for flash sales, distributed locks, rate limiting, cart operations +- **Message Queues**: Pub/Sub for order status changes and inventory updates + +## Common Development Commands + +### Build and Run + +```bash +# Compile project +mvn clean compile + +# Run application +mvn spring-boot:run + +# Package application +mvn clean package +``` + +### Testing + +```bash +# Run all tests +mvn test + +# Run specific

+### Key Configuration Files + +- `application.yml`: Main application configuration including Redis cluster, database, and custom flash sale settings +- `pom.xml`: Maven dependencies and build configuration +- `src/main/resources/lua/`: Lua scripts for Redis atomic operations + +### Important Configuration Sections + +- **Redis Cluster**: Configured for 6-node cluster with authentication +- **Flash Sale Settings**: Rate limiting (10 requests/minute), max quantity per user (1), stock preload timing +- **Cache TTL**: User info (30min), product info (60min), flash sale data (10min) +- **Database**: HikariCP connection pool with optimized settings + +## Development Guidelines + +### Service Layer Patterns + +- All Redis operations use Redisson for cluster support +- Critical operations (stock deduction, cart updates) use Lua scripts for atomicity +- Distributed locks prevent overselling using Redisson's RLock +- Rate limiting implemented via sliding window algorithm in Lua + +### Key Services + +- **FlashSaleService**: Core flash sale logic with distributed locking and Lua scripts +- **RedisService**: Generic Redis operations wrapper +- **DistributedLockService**: Distributed locking abstraction +- **RateLimitService**: API rate limiting using Redis +- **CartService**: Shopping cart operations with Redis Hash storage + +### Testing Approach + +- Unit tests exist for core services (FlashSaleServiceTest, RedisServiceTest) +- Integration tests should verify Redis cluster connectivity +- Load testing recommended for flash sale scenarios + +## Lua Script Usage + +The system includes 5 Lua scripts in `src/main/resources/lua/`: + +- `flashsale.lua`: Atomic stock deduction with overselling prevention +- `distributed_lock.lua`: Distributed lock acquisition +- `unlock.lua`: Safe distributed lock release +- `rate_limit.lua`: Sliding window rate limiting +- `cart_operation.lua`: Atomic shopping cart operations + +## API Documentation + +-
