lwebserver's Introduction

仿Tomcat简化版Servlet容器

通过搭建简单HTTP服务器，学习服务器原理和计算机网络知识

学习内容：

  • IO模式
  • Socket
  • TCP/IP
  • 框架源码(Tomcat,Spring,Netty等)
  • 高级网络编程
  • 线程模型

实现的简化功能：

  • BIO NIO AIO

NIO使用的是IO多路复用的Select机制

  • HTTP Protocol

Keep-Alive

  • Servlet

ServletContext Dispatcher

  • Request&Response

  • Forward&Redirect

  • session&cookie

使用技术

基于Java BIO/NIO/AIO(NIO2)、多线程（select）、Socket网络编程、XML解析、log4j/slf4j日志

模式

  • 当前NIO的实现参照的是Tomcat的源码

解决问题

  • AIO的高错误率，backlog参数的调节issue
  • NIO下对Socket实现长连接(keep-alive)，并设置心跳定时清理
  • 分析多余的socket连接issue

准备添加的功能：

  • SSL
  • limtlatch
  • 辅Selector
