struts2框架的搭建(基础)

1.首先把struts2中的包导入:
   commons-logging.jar
   commons-logging-api.jar
   freemaker.jar
   struts-core.jar
   ognl.jar
   struts2-core.jar
   xwork.jar  

 

2.下面是web.xml的配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app 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">
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.FilterDispatcher
        </filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
  <welcome-file-list>
    <welcome-file>HelloWorld.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3.struts.xml这样写(代替了struts-config.xml)

<!DOCTYPE struts PUBLIC  
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  
        "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <package name="struts2demo" extends="struts-default">
        <action name="HelloWorld" class="tutorial.HelloWorld">
            <result>/HelloWorld.jsp</result>
        </action>
    </package>
</struts>

 

4:JSP页面中Struts2标签的导入。

<%@ taglib prefix="s" uri="/struts-tags"%>
