1.創建form表單
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!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=UTF-8"beanForm.jsp> <title>Insert title here</title> </head> <body> <div style="margin-left:500px;"> <form action="testBean.jsp" method="post" name="f1"> <table> <tr> <td align="right">用戶名：</td> <tdalign="left"> <input type="text" name="userName"></input> </td> </tr> <tr> <td align="right">密碼：</td> <td align="left"> <input type="password"maxlength="16" id="mima" name="password"></input> </td> </tr> <tr> <td align="right">性別：</td> <td align="left" > <input type="radio" name="sex" value="男"/>男 <input type="radio" name="sex" value="女"/>女 </td> </tr> <tr> <td align="right">年齡：</td> <td align="left" > <input name="age" type="number" /> </td> <tr> <td align="right">個人愛好：</td> <td align="left"> <input type="checkbox" name="hobby" value="運動"/>運動 <input type="checkbox" name="hobby" value="睡覺"/>睡覺 <input type="checkbox" name="hobby" value="購物"/>購物 <input type="checkbox" name="hobby" value="上網"/>上網 </td> </tr> <tr> <td colspan="2" align="center"> <input type="submit"/> <input type="reset"/> </td> </tr> </table> </form> </div> </body> </html>
2.在服務器中創建javaBean類
package com.serv; public class Student { //屬性 private String userName; private String password; private String sex; private Integer age; private String[] hobby; private String hobbys=""; //提供set和get方法 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 getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } public String[] getHobby() { return hobby; } public void setHobby(String[] hobby) { this.hobby = hobby; } public String getHobbys() { //將String數組轉化成String字符串，便於取值； int len=this.hobby.length; if(len>0) { for(String str:hobby) { hobbys+=str+","; } } hobbys=hobbys.substring(0,hobbys.length()-1); return hobbys; } public void setHobbys(String hobbys) { this.hobbys = hobbys; } }
3.前段或者後臺取值
package com.serv; public class Student { //屬性 private String userName; private String password; private String sex; private Integer age; private String[] hobby; private String hobbys=""; //提供set和get方法 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 getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } public String[] getHobby() { return hobby; } public void setHobby(String[] hobby) { this.hobby = hobby; } public String getHobbys() { //將String數組轉化成String字符串，便於取值； int len=this.hobby.length; if(len>0) { for(String str:hobby) { hobbys+=str+","; } } hobbys=hobbys.substring(0,hobbys.length()-1); return hobbys; } public void setHobbys(String hobbys) { this.hobbys = hobbys; } }testBean.jsp
