## 👋简介
|
||
大家好呀，我是Lex👨💻。我是一名拥有8年经验的Java 后端开发人员👨💼，也是一个对 Spring 框架充满热情❤️的程序员。为了帮助那些希望深入了解 Spring 框架的程序员们🧑💻，我创建了这个 “Spring 源码阅读系列”📖。通过这个系列，我希望能够与你们共同探索 Spring 的内部工作机制⚙️。如果您有同样的兴趣或问题🤔，请联系我📩！
|
||
|
||
## 🍵**为何做Spring源码分析**
|
||
在我作为框架研发的开发者👨🔬的工作中，我经常遇到需要深入理解和调整框架行为的情况🔧。这些工作不只是简单地使用框架的API，更多地是需要对框架的内部工作方式有详细的了解🔍。虽然Github上有关于Spring的简化版本📦，这些对于入门学习确实有很大的帮助✅，但当涉及到真实的项目应用时，与真正的Spring框架还是有很大的差异❌。因此，我开始深入研究Spring的源码，希望能够更透彻地理解其内部的工作机制，以便更好地应用到我的实际工作中🧰。分享我的源码分析📝，也是为了给那些希望真正理解Spring，而不仅仅是使用它的开发者提供一些参考和帮助🙌。
|
||
|
||
## 🙏顺手点个星
|
||
亲爱的朋友们👥，我真的花了很多心思💭去研究和整理这个“Spring 源码阅读系列”📘。如果你觉得这东西还不错👍，或者给你带来了一点点帮助🤗，麻烦点一下星星吧🌟。这真的对我意义重大🎖，每一颗星✨都能让我觉得所有的努力都是值得的💪。我知道这是小事一桩，但你的那一下点击🖱，对我来说就是最好的鼓励🎉。无论如何，都要感谢你抽时间🕰阅读我的内容，真的很感激🙏！
