javaEETomcatserver.xml详解

Tomcat Server处理一个http请求的过程
假设来自客户的请求为&＃xff1a;

http://localhost:8080/wsota/wsota_index.jsp

1) 请求被发送到本机端口8080&＃xff0c;被在那里侦听的Coyote HTTP/1.1 Connector获得
2) Connector把该请求交给它所在的Service的Engine来处理&＃xff0c;并等待来自Engine的回应
3) Engine获得请求localhost/wsota/wsota_index.jsp&＃xff0c;匹配它所拥有的所有虚拟主机Host
4) Engine匹配到名为localhost的Host&＃xff08;即使匹配不到也把请求交给该Host处理&＃xff0c;因为该Host被定义为该Engine的默认主机&＃xff09;
5) localhost Host获得请求/wsota/wsota_index.jsp&＃xff0c;匹配它所拥有的所有Context
6) Host匹配到路径为/wsota的Context&＃xff08;如果匹配不到就把该请求交给路径名为”"的Context去处理&＃xff09;
7) path&＃61;”/wsota”的Context获得请求/wsota_index.jsp&＃xff0c;在它的mapping table中寻找对应的servlet
8) Context匹配到URL PATTERN为*.jsp的servlet&＃xff0c;对应于JspServlet类
9) 构造HttpServletRequest对象和HttpServletResponse对象&＃xff0c;作为参数调用JspServlet的doGet或doPost方法
10)Context把执行完了之后的HttpServletResponse对象返回给Host
11)Host把HttpServletResponse对象返回给Engine
12)Engine把HttpServletResponse对象返回给Connector
13)Connector把HttpServletResponse对象返回给客户browser
