struts2 关于运行机制的一些笔记

apach接收到一个请求后http://localhost:8080/AAAA/hello

以后去找web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<display-name>Struts Blank</display-name>

<filter>

<filter-name>struts2</filter-name>

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>//处理请求：首先找你的NAMESPACE（这里是AAAA后面的“/”）

</filter>

<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>//过滤所有的URL地址

</filter-mapping>

<welcome-file-list>

<welcome-file>index.html</welcome-file>

</welcome-file-list>

</web-app>

struts2.xml namespace

<package name="default" namespace="/" extends="struts-default">

<action name="hello">

<result>

/hello.jsp

</result>

</action>

</package>

whatever 记下先
