如何在JSP表单中添加数据库表中相关记录???附代码~
HTML code<%@ page language="java" import="java.util.*,java.sql.*,bao.*" pageEncoding="UTF-8"%><% request.setCharacterEncoding("UTF-8"); //从上一页面获得用户提交表单 String sSchlNumber,sPassword; sSchlNumber = request.getParameter("schlNumber"); sSchlNumber = sSchlNumber.replaceAll("'","''"); sPassword = request.getParameter("password"); sPassword = sPassword.replaceAll("'","''"); //检索该用户输入的信息是否正确 String query = "select * from student where 学号='" + sSchlNumber + " ' and 密码 = '" + sPassword + " '"; Connection conn=null; Statement stmt=null; ResultSet rs=null; try{ //获得数据库连接 Class.forName("com.mysql.jdbc.Driver").newInstance(); conn = DriverManager.getConnection("jdbc:mysql://localhost/wode?user=root&password=123456"); //创建statement stmt = conn.createStatement(); //执行查询 rs = stmt.executeQuery(query); /* String num = rs.getString(1); String name = rs.getString(2); String sex = rs.getString(4); String pwd = rs.getString(3); String xueyuan = rs.getString(6); String zhuanye = rs.getString(7); String jiguan = rs.getString(8); String note = rs.getString(9); String room = rs.getString(5); 这样定义也不对,显示有错误 */ if(rs.next()) { //往session里设置相关属性 session.setAttribute("学号",sSchlNumber); // System.out.println(rs.getString(1)); 这句话也显示不出来 } else{ response.sendRedirect("error.jsp"); } } catch(SQLException ex) { ex.printStackTrace(); response.sendRedirect("error.jsp"); return; }finally{ //关闭数据库 stmt.close(); conn.close(); }%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html> <head> <title>学生宿舍管理系统登录验证界面-by8421</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> </head> <body> <br><br><br> <center><h2>你的基本信息如下,请检查,如有错误请及时联系管理员!</h2> <table border ="1" cellpadding="0" cellspacing="0"> <tr> <td>学号:</td><td><%=System.out.println(rs.getString(1))%></td> </tr> <tr> <td>密码:</td><td><%="pwd"%></td> </tr> <tr> <td>姓名:</td><td><%="name"%></td> </tr> <tr> <td>性别:</td><td><%="sex"%></td> </tr> <tr> <td>院系:</td><td><%="xueyuan"%></td> </tr> <tr> <td>寝号:</td><td><%="room"%></td> </tr> <tr> <td>专业:</td><td><%="zhuanye"%></td> </tr> <tr> <td>籍贯:</td><td><%="jiguan"%></td> </tr> <tr> <td>备注:</td><td><%="note"%></td> </tr> </table><input type="button" value="返回" onclick="window.location = 'login-stu.jsp'"/><br><hr> </center> </body></html>
