先写好表单的html页面form.html
<!DOCTYPE html>
<html>
<head>
<title>form.html</title>
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="this is my page">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<!--<link rel="stylesheet" type="text/css" href="./styles.css">-->
</head>
<body>
<form action="/RequestTest/servlet/GetFormInf" method="post">
UserName: <input type="text" name="username"></br>
PassWord: <input type="password" name="password"></br>
Gender: <input type="radio" name="gender" value="male">male
<input type="radio" name="gender" value="female">female</br>

</select>
</br>
Likes: <input type="checkbox" name="likes" value="sing">Sing
<input type="checkbox" name="likes" value="dance">Dance
<input type="checkbox" name="likes" value="basketball">BasketBall

<!--隐藏输入项-->
<input type="hidden" name="id" value="123456">
<input type="submit" value="submit">
</form>
</body>
</html>
再写好GetFormInf.java
package RequestDemo;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class GetFormInf extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
System.out.println(request.getParameter("username"));
System.out.println(request.getParameter("password"));
System.out.println(request.getParameter("gender"));
System.out.println(request.getParameter("city"));
String[] likeString = request.getParameterValues("likes");
for(int i=0;likeString!=null && i<likeString.length;i++)
{
System.out.println(likeString[i]);
}
System.out.println(request.getParameter("description"));
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
doGet(request, response);
}
}
在浏览器中浏览form.html,如下图所示:
填写相关数据提交后,在终端中会显示:
