freemarker-2.3.8.jar
struts2-core-2.0.11.jar
xwork-2.0.4.jar
ognl-2.6.11.jar

2.修改Tomcat server.xml

< Context  path ="/struts2"  docBase ="E:\MyEclipse\struts2\WebRoot"  reloadable ="true"   />

3.修改项目 部署配置文件web.xml

< filter >
     < filter-name > struts </ filter-name >
     < filter-class > org.apache.struts2.dispatcher.FilterDispatcher </ filter-class >
</ filter >

< filter-mapping >
     < filter-name > struts </ filter-name >
     < url-pattern > /* </ url-pattern >
</ filter-mapping >

3.新建class处理action

package  org.test.struts.action;

public   class  ActionLogin  {
    private String username;
    private String password;
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String execute() throws Exception{
        return "success";
    }
}

3.新建struts.xml
在WebRoot/WEB-INF/classes文件夹下

<? xml version="1.0" encoding="UTF-8"  ?>
<! DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd" >
< struts >
     < package  name ="struts"  extends ="struts-default" >
         < action  name ="login"  class ="org.test.struts.action.ActionLogin"   >
             < result  name ="success"   > /result.jsp </ result >
         </ action >
     </ package >
</ struts >

4.建立login.jsp

     < form  action ="login.action"  method ="post" >
        username: < input  type ="text"  name ="username"   />< br >
        password: < input  type ="password"  name ="password"   />< br >
