netty-boot
简介
Netty-Boot
是一个基于 Netty 的轻量级 Web 中间件框架,专为高性能 Web 应用开发而设计。它充分利用了 Netty 的高效 IO 模型,支持快速开发高并发的 Web 服务。该框架整合了多种常见的中间件,包括 PostgreSQL、Redis、MongoDB、Elasticsearch、消息队列(MQ)、Dubbo 等,提供了强大的扩展能力,使开发者能够专注于业务逻辑开发。
Netty-Boot
的目标是简化 Netty 的使用,提供类似 Spring Boot 的易用性,帮助开发者轻松构建基于 Netty 的 Web 应用,同时享受 Netty 带来的高性能和可扩展性。
特性
- 高性能:基于 Netty 的异步非阻塞 IO,支持高并发和大规模连接。
- 模块化设计:支持 PostgreSQL、Redis、MongoDB、Elasticsearch、消息队列(MQ)和 Dubbo 等中间件的无缝集成。
- 灵活性:通过注解驱动的组件扫描和依赖注入,简化配置,增强代码的可维护性。
- WebSocket 支持:轻松实现 WebSocket 通信,支持长连接和实时数据推送。
- 易扩展性:通过 AOP 和自定义中间件,开发者可以扩展 Netty-Boot 的功能,满足复杂业务需求。
