“技术深度” 与 “技术广度”是对开发者来说最为重要的两个维度,本项目致力于从源码层面,剖析和挖掘互联网行业主流技术的底层实现原理,**为广大开发者 “提升技术深度” 提供便利**。
加入我们,一起通读互联网行业主流框架及中间件源码,成为强大的 “源码猎人”,目前开放的有 **Spring 全家桶**、**Mybatis**、**Netty**、**Dubbo 框架**,及 **Redis**、**Tomcat** 中间件等,让我们一起开拓新的领地,揭开这些源码的神秘面纱。
本项目主要用于记录框架及中间件源码的阅读经验、个人理解及解析,希望能够使阅读源码变成一件简单有趣,且有价值的事情,抽空更新中... (如果本项目对您有帮助,请 watch、star、fork 素质三连一波,鼓励一下作者,谢谢)
