一、创建一个javaBean类： UseBean
package com.oncall24h.ruchi; import java.io.Serializable; public class UseBean implements Serializable { private String username; private String password; public UseBean() { super(); } 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; } }
二、创建表单所在的JSP页面 register.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Register</title> </head> <body> <form action="do_register.jsp" method="post"> USERNAME: <input type="text" name="yonghuming"/> PASSWORD: <input type="password" name="mima"/> <input type="submit" value="submit"/> </form> </body> </html>
三、创建表单数据传到的Jsp页面 do_register.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Handle</title> </head> <body> <jsp:useBean id="user" class= "com.oncall24h.ruchi.UseBean"></jsp:useBean> <%-- user is an arbitrary identifier , UseBean is the defined class name which is the same as: UseBean user= new UseBean(); --%> <jsp:setProperty property="username" name="user" param="yonghuming"/> <%-- the same as: user.setUsername("yonghuming"); // yonghuming comes from the form of register.jsp --%> <jsp:setProperty property="password" name="user" param="mima"/> <%-- the same as: user.setPassword("mima"); // mima comes from the form of register.jsp --%> <jsp:getProperty property="username" name="user"/> <%-- the same as: user.getUsername("username"); //username is the property of class UseBean --%> <jsp:getProperty property="password" name="user"/> <%-- the same as: user.getPassword("password"); //password is the property of class UseBean --%> </body> </html>
