3.配置web.xml

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

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

	</form>
</body>

5.新建一个Action类

package com.zchen.struts.action;

public class LoginAction {

	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() {
		return "success";

	}

}

6.配置struts.xml文件

<?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="struts2" extends="struts-default">
		<action name="login" class="com.zchen.struts.action.LoginAction">

		</action>
	</package>
</struts>

7.新建一个result页面

<body>
	username:${requestScope.username }<br>
	password:${requestScope.password }<br>
</body>
