Project Introduction

HuLa-Server is an instant messaging system server built with SpringBoot3, Netty, MyBatis-Plus and RocketMQ. It adopts a microservice architecture design, providing high-performance real-time communication capabilities, supporting core features such as private chat, group chat, and message push. The system has high scalability and reliability, suitable for various instant messaging scenarios.

Technology Stack

• SpringBoot 3: The latest version of the Spring Boot framework, providing a more modern Java development experience, supporting GraalVM native images, using Jakarta EE API, with better performance and lower memory consumption.

• Netty: A high-performance asynchronous event-driven network application framework, used to implement WebSocket long connection services, ensuring message real-time and reliability. Netty's high concurrent processing capability and excellent network programming model enable the system to support a large number of simultaneous online clients.

• MyBatis-Plus: Provides powerful enhancement functions and plugins for MyBatis, simplifies database operations, provides code generator, pagination plugin, performance analysis, and other features, greatly improving development efficiency.

• RocketMQ: A distributed message middleware, used for handling asynchronous communication between systems, supporting reliable message delivery, sequential messages, transaction messages, and other features, ensuring system scalability and decoupling.

• Redis: A high-performance in-memory database, used to store user session information, message cache, and other data, providing high-speed data access capabilities.

• MySQL: A reliable relational database, used to store user information, message records, and other persistent data.

• WebSocket: Implements full-duplex communication between client and server, supporting real-time message push.
