新建GoLogin.java和LoginServlet.java的servlet類

分別修改他們的doGet和doPost方法

login.jsp:

1  <form action="servlet/LoginServlet" method="post">2         <table>3             <tr><td>用戶名:</td><td><input type="text" name="username" /></td></tr>4             <tr><td>密碼:</td><td><input type="password" name="password" /></td></tr>5             <tr><td></td><td><input type="submit" value="登陸" /></td></tr>6         </table>7     </form>
