Tomcat架构-请求处理流程

Engine

自动配置加载流程-TomcatServletWebServerFactory1、启动时，根据以下时序图加载ServletWebServerFactoryAutoConfiguration2、通过@Import({ServletWebServerFactoryConfiguration.EmbeddedTomcat.class})加载EmbeddedTomcat3、ServletWebServerFactoryConfiguration中通过@Bean声明了TomcatServletWebServerFactory

请求处理流程时序图：https://tomcat.apache.org/tomcat-9.0-doc/architecture/requestProcess/request-process.png

连接器 Connector监听网络端口；接受网络请求；读取网络字节流；根据应用层协议解析字节流，生成统一的 tomcat request 和 tomcat response 对象；将 tomcat request 对象转成 servletRequest；调用 servlet 容器，得到 servletResponse；将 servletResponse 转成 tomcat response；将 tomcat response 转成网络字节流；将响应字节流写回给浏览器；
