前置条件添加struts2的jar包
配置web.xml前端控制器
<filter> <filter-name>Struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>Struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
配置struts.xml的配置文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="helloworld" extends="struts-default"> <action name="welcome" class="com.tarena.action.WelcomeAction"> <result name="success">/jsp/welcome.jsp</result> <result name="fail">/jsp/nameform.jsp</result> </action> </package> </struts>
根据配置文件添加jsp页面
nameform.jsp静态页面
<%@page pageEncoding="utf-8"%> <html> <head> <title>Hello World</title> </head> <body> <form action="HelloWorld/welcome.action" method="get"> <table> <tr> <td> 姓名： </td> <td> <input name="name" type="text" /> </td> </tr> <tr> <td> 密码： </td> <td> <input name="password" type="text" /> </td> </tr> <tr> <td></td> <td> <input type="submit" value="Submit" /> </td> </tr> </table> </form> </body> </html>
welcome.jsp静态页面
<%@page pageEncoding="utf-8"%> <html> <head> <title>Welcome</title> </head> <body> <h1> Welcome, ${name} </h1> </body> </html>
添加java类
package com.tarena.action; public class WelcomeAction{ private String name; private String password; public String execute() { if ("name".equalsIgnoreCase(name)) { return "fail"; } return "success"; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
