1.创建form表单
<%@ 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">
<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">用户名：</td>
<td align="left">
<input type="text" name="userName"></input>
</td>
</tr>
<tr>
<td align="right">密码：</td>
<td align="left">
<input type="password" maxlength="16" id="mima" name="password"></input>
</td>
</tr>
<tr>
<td align="right">性别：</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">年龄：</td>
<td align="left" >
<input name="age" type="number" />
</td>
<tr>
<td align="right">个人爱好：</td>
<td align="left">
<input type="checkbox" name="hobby" value="运动"/>运动
<input type="checkbox" name="hobby" value="睡觉"/>睡觉
<input type="checkbox" name="hobby" value="购物"/>购物
<input type="checkbox" name="hobby" value="上网"/>上网
</td>
</tr>
<tr>
<td colspan="2" align="center">
<input type="submit"/>
<input type="reset"/>
</td>
</tr> </table>
</form>
</div>
</body>
</html>
beanForm.jsp
2.在服务器中创建javaBean类
package com.serv; public class Student
{
//属性
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()
{
//将String数组转化成String字符串，便于取值；
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.前段或者后台取值
package com.serv; public class Student
{
//属性
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()
{
//将String数组转化成String字符串，便于取值；
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;
} }
