昨天发了一下其他相关知识的一些代码，所以从今天开始更新那个选课系统的代码！
先从前端界面代码开始！
登录界面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Insert title here</title> </head> <body> <div id="addSubjectForm" align="center"> <form action="SchoolServlet" method="post"> <tr> <h1>学校教务系统 </h1> </tr> <table align="center"> <tr> <td>身份： <select name="profession"> <option value="1">管理员</option> <option value="2">教师</option> <option value="3" selected>学生</option> </select> </td> </tr> <tr><td> 用户名:<input pattern="[a-zA-Z0-9]{6,12}" name="username"></td></tr> <tr><td> 密码:<input pattern="[a-zA-Z0-9]{6,12}" type="password" name="password"></td> </tr> </tr> <tr> <td colspan="2"><div align="center"> <input type="submit" value="登录"></div></td> </tr> </table> </form> </div> </body> </html>
