登陆界面：
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <form action=success> <label align="left" for="user">用户名：<input type=text name="user" name="user" id="user"></label><p></p> <label align="left" for="password">密码 ：<input type=password name="password" id="password" name="password"></label><P></P> <input type=submit value="登陆"> <input type="reset" value="重置"> </form> </body> </html>
form表单action属性提交到success,配置文件里面name值与之对应，class表示提交到的处理类，method指定处理方法，当没有method值时，会用默认方法execute替代，result里面的name值对应LoginAction返回值
<action name="success" class="com.chen.Action.LoginAction" method="login" > <result name="success">/success.jsp</result> <result name="error">/error.jsp</result> <result name="user">/user.jsp</result> </action>
LoginAction类代码
public class LoginAction extends ActionSupport { private String user; private String password; public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getUser() { return user; } public void setUser(String user) { this.user = user; } @Override public String execute() throws Exception { // TODO Auto-generated method stub System.out.println("成功登陆"); return "success"; } public String login(){ if(user.equals("chen")){ if(password.equals("1234")){ return "success"; } return "error"; } return "error"; } }
