在index.jsp添加相關(guān)的代碼

<%@ 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">

<body>

<h1>用戶注冊</h1>
<div>
    <form action="RegisterServlet" method="get">
    <table>
    <tr>
    <td>登錄名：</td> 
    <td><input type="text" name="username" required> (可包含a-z、0-9和下劃線)</td>
    </br>
    <tr>
    <td>密碼：</td> 
    <td><input type="password" name="password" required> (至少包含6個字符)</td>
    </tr>
    <tr>
    <td>再次輸入密碼：</td>

    </td>
    </tr>
   
     </tr>
     <td>喜歡的城市：</td> 
    <td>
         <select name="selectList">
