一.这一章从头构建一个简单的Servlet容器,可以处理Servlet和静态资源(如html文件/图片等). 要处理Servlet,必须遵循javax.servlet.Servlet规范,而处理静态资源同第一章. 关键是模仿tomcat的结构,来合理组织代码. 首先,servlet规范规定javax.servlet.Servlet接口有5个方法,签名如下: public void init(ServletConfig config) throws ServletException public…

1 在这个博客中,我将描述一下web服务器.Servlet容器的基本概念,以及Servlet容器和jvm之间的关系.我想要证明的是Servlet容器不过就是一个java程序. 2 什么是web服务器 在了解什么是Servlet容器前,我们需要先知道什么是web服务器. web服务器使用http协议传输数据.下面是一个简单的例子:一个用户在浏览器中输入一个url(例如,www.baidu.com),然后它将会获取到一个web页面.因此,web服务器做的事情是发送一个web页面给浏览器.http协议…

这算是一篇读书笔记,留着以后复习看看. Web Server又称为Http Server,因为它使用HTTP协议和客户端(一般是各种各样的浏览器)进行通信. 什么是HTTP协议呢? HTTP协议是基于有状态的TCP协议(默认的的TCP端口是80),最早版本的HTTP协议是HTTP/0.9,然后被HTTP/1.0代替了,代替HTTP/1.0的是现在使用的HTTP/1.1,详细介绍可以看RFC(请求注释)文档:http://www.w3.org/Protocols/HTTP/1.1/rfc2616.…

1 spring boot内嵌容器支持tomcat.jetty和undertow 但是undertow性能最好,详见: https://examples.javacodegeeks.com/enterprise-java/spring/tomcat-vs-jetty-vs-undertow-comparison-of-spring-boot-embedded-servlet-containers/…
