Tomcat源码解读系列（二）——Tomcat的核心组成和启动过程

?

????????? Tomcat在接收到用户请求时，将会通过以上组件的协作来给最终用户产生响应。首先是最外层的Server和Service来提供整个运行环境的基础设施，而Connector通过指定的协议和接口来监听用户的请求，在对请求进行必要的处理和解析后将请求的内容传递给对应的容器，经过容器一层层的处理后，生成最终的响应信息，返回给客户端。

?在介绍请求的处理过程时，将会详细介绍各个组件的作用和处理流程。本文将会主要分析Tomcat的启动流程，介绍涉及到什么组件以及初始化的过程，简单期间将会重点分析HTTP协议所对应Connector启动过程。
