Java相关流行框架源码分析，学习以及总结，项目持续更新中。

框架或者源码包括：

✅  JDK源码

✅  JUC源码

✅  Spring源码

✅  SpringBoot源码

✅  SpringAOP源码

✅  SpringSecurity源码

✅  SpringSecurity OAuth2源码

✅  JDK源码

✅  Dubbo源码

✅  Netty源码

✅  RocketMQ源码

✅  kafka源码

> 为什么要分析、学习源码？

  学习框架源码不仅能帮助我们在实际问题出现时快速定位问题、理解根因并高效解决，还能深入掌握框架的整体架构设计思路与核心设计模式，从而提升自身的系统设计能力与架构思维。
同时，通过学习优秀开源框架的底层实现，可以不断强化对复杂系统拆分、模块协作以及性能优化的理解，这对于个人技术能力的长期成长至关重要。因此，源码学习虽然过程相对枯燥，但这是提升架构设计能力的必经路径。只有持续积累，才能在实际系统设计与工程实践中做到真正的“游刃有余”。
