手写Tomcat 自己动手，从零开发一个迷你版Tomcat服务器！ 廖雪峰 2025-06-16 https://liaoxuefeng.com/books/jerrymouse/ 目录 简介 设计服务器架构 Servlet规范 实现HTTP服务器 实现Servlet服务器 实现Servlet组件 6.1. 实现ServletContext 6.2. 实现FilterChain 对于Java后端开发的同学来说，Tomcat服务器肯定不陌生。开发Java Web App，最后通常都会部署到Tomcat这样的服务器上。 很多同学可能觉得开发Web App是比较容易的，开发Web服务器就比较困难了。实际上，虽然开发Web服务器的难度比开发Web App要高，但也不是高得特别离谱。 对于已经能熟练开发Web App的同学来说，要进一步提升自己的架构水平，不如自己动手，从零开始编写一个Tomcat服务器。 本教程的目标就是以Tomcat服务器为原型，专注于实现一个支持Servlet标准的Web服务器，即实现一个迷你版的Tomcat Server，我们把它命名为Jerrymouse Server，与Tomcat主要区别在于，它俩的图标有所不同： Tomcat Server Jerrymouse Server Jerrymouse Server设计目标如下： 支持Servlet 6的大部分功能：
