public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException response.setCharacterEncoding("GB2312"); String studentnumber = request.getParameter("studentnumber"); String name = request.getParameter("name"); String sex = request.getParameter("sex"); String pro = request.getParameter("pro"); String classes = request.getParameter("classes"); String telephone = request.getParameter("telephone"); String password = request.getParameter("password"); tryConnection con=DriverManager.getConnection(url, "root","zxzxzx55"); String sql="insert into student(studentnumber,name,sex,pro,classes,telephone,password) values(?,?,?,?,?,?,?)"PreparedStatement pstm=con.prepareStatement(sql); pstm.setString(1, studentnumber); pstm.setString(2, name); pstm.setString(3, sex); pstm.setString(4, pro); pstm.setString(5, classes); pstm.setString(6, telephone); pstm.setString(7, password); PrintWriter out=response.getWriter(); int row=pstm.executeUpdate(); pstm.close(); con.close(); if(row>0) out.println("注册成功"); HttpSession session=request.getSession(true); session.setAttribute("sn", studentnumber); session.setAttribute("n", name); session.setAttribute("s", sex); session.setAttribute("p", pro); session.setAttribute("c", classes); session.setAttribute("te", telephone); session.setAttribute("pass", password); response.setHeader("refresh","2;URL=loginJudge.jsp"); else out.println("注册失败"); response.setHeader("refresh","2;URL=loginJudge.jsp"); catch(ClassNotFoundException e) PrintWriter out=response.getWriter(); out.println("errorclass");e.printStackTrace();response.setHeader("refresh","2;URL=loginJudge.jsp");catch(SQLException e)PrintWriter out=response.getWriter();out.println("用户名已被注册");e.printStackTrace();response.setHeader("refresh","2;URL=loginJudge.jsp");实验三：JSP技术的基础应用及程序设计一、实验目的掌握JSP语法及内置对象，并能够使用JSP开发Web页面。二、实验原理JSP技术是一个基于纯Java平台的技术，它主要用来产生动态网页内容。JSP实现了将静态内容和动态内容混合编码的技术。三、实验程序<%page language="java" contentType="text/html;charset=gb2312"%><%page import="java.sql.*"%><html><head><title>LoginJudge Page</title></head><body><%String studentnumber = request.getParameter("studentnumber");String password = request.getParameter("password");try Connection con = null;/数据库连接 Statement stm = null;/数据库表达式 ResultSet rs = null;/结果集 stm = con.createStatement(); String sql = "select * from student" rs = stm.executeQuery(sql); out.println("<table border=2>"); out.println("<tr><td>学号</td><td>姓名</td><td>性别</td><td>专业</td><td>班级</td><td>手机号</td><td>密码</td></tr>"); while (rs.next() if(rs.getString(1)=studentnumber&&rs.getString(7)=password) out.println("登陆成功"); break; out.println("<tr><td>"+ rs.getString(1)+"</td><td>"+ rs.getString(2) +"</td><td>"+ rs.getString(3) +"</td><td>"+ rs.getString(4)+"</td><td>"+ rs.getString(5)+"</td><td>"+ rs.getString(6)+"</td><td>"+ rs.getString(7)+"</td></tr>"); out.println("</table>"); rs.close(); stm.close(); con.close(); catch(Exception e) out.println(e.getMessage();%></body></html>4、实验结果实验四：JDBC数据库连接技术及其程序设计一、实验目的熟悉MySQL数据库系统的使用，掌握JDBC的基本原理以及编程接口的使用，能够开发数据库应用。二、实验原理JDBC是一种用于执行SQL语句的JavaAPI。它由一组用Java编程语言编写的类和接口组成。JDBC为工具/数据库开发人员提供了一个标准的API，使他们能够用纯JavaAPI来编写数据库应用程序。三、实验程序package com.demo;import java.io.*;import java.sql.*;import javax.servlet.*;public class saveregister extends HttpServlet public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException this.doPost(request,response); public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException response.setCharacterEncoding("GB2312"); tryConnection con=DriverManager.getConnection(url, "root","zxzxzx55"); String sql="insert into student(studentnumber,name,sex,pro,classes,telephone,password) values(?,?,?,?,?,?,?)"PreparedStatement pstm=con.prepareStatement(sql); pstm.setString(1, studentnumber); pstm.setString(2, name); pstm.setString(3, sex); pstm.setString(4, pro); pstm.setString(5, classes); pstm.setString(6, telephone); pstm.setString(7, password); PrintWriter out=response.getWriter(); int row=pstm.executeUpdate(); pstm.close(); con.close(); if(row>0) out.println("注册成功"); HttpSession session=request.getSession(true); session.setAttribute("sn", studentnumber); session.setAttribute("n", name); session.setAttribute("s", sex); session.setAttribute("p", pro); session.setAttribute("c", classes); session.setAttribute("te", telephone); session.setAttribute("pass", password); response.setHeader("refresh","2;URL=loginJudge.jsp"); else out.println("注册失败"); response.setHeader("refresh","2;URL=loginJudge.jsp"); catch(ClassNotFoundException e) PrintWriter out=response.getWriter(); out.println("errorclass");e.printStackTrace();response.setHeader("refresh","2;URL=loginJudge.jsp");catch(SQLException e)PrintWriter out=response.getWriter();out.println("用户名已被注册");e.printStackTrace();response.setHeader("refresh","2;URL=loginJudge.jsp");4、实验结果实验五：深入JDBC开发及JavaBean技术应用一、实验目的掌握能够使用JavaBean组件模型增加代码的重用性。二、实验原理JavaBean被称为是Java组件技术的核心。JavaBean使得开发人员可以把某些关键功能和核心算法提取出来封装成为一个组件对象，这样就增加了代码的重用性和系统的安全性。三、实验程序package com.demo;public class demo private String name; private String password1; public String getname() return name; public void setname(String name) this.name = name; public String getPassword1() return password1; public void setPassword1(String password1) this.password1 = password1; 实验六：基于MVC模式系统整合开发一、实验目的MVC是一种设计模式，目的就是实现Web系统的职能分工。使用JSP、Servlet、JavaBean实现MVC。二、实验原理Controller，负责用户界面和业务逻辑层的通信控制，一方面解释来自用户界面的输入，识别用户动作（如点击按钮等），调用相应Model中的方法，另一方面处理来自Model的事件和返回的执行结果，调用适当的View显示给用户，Controller主要由Servlet完成。Model，负责整个解决方案的业务逻辑实现，底层的数据库也由Model访问和操作。View负责系统向用户的展示，主要由HTML及JSP等完成。三、实验程序<%page language="java" contentType="text/html;charset=gb2312"%><%page import="java.sql.*"%><html><head><title>LoginJudge Page</title></head><body><%String studentnumber = request.getParameter("studentnumber");String password = request.getParameter("password");try Connection con = null;/数据库连接 Statement stm = null;/数据库表达式 ResultSet rs = null;/结果集 stm = con.createStatement(); String sql = "select * from student" rs = stm.executeQuery(sql); out.println("<table border=2>"); out.println("<tr><td>学号</td><td>姓名</td><td>性别</td><td>专业</td><td>班级</td><td>手机号</td><td>密码</td></tr>"); while (rs.next() if(rs.getString(1)=studentnumber&&rs.getString(7)=password) out.println("登陆成功"); break; out.println("<tr><td>"+ rs.getString(1)+"</td><td>"+ rs.getString(2) +"</td><td>"+ rs.getString(3) +"</td><td>"+ rs.getString(4)+"</td><td>"+ rs.getString(5)+"</td><td>"+ rs.getString(6)+"</td><td>"+ rs.getString(7)+"</td></tr>"); out.println("</table>"); rs.close(); stm.close(); con.close(); catch(Exception e) out.println(e.getMessage();%></body></html>package com.demo;import java.io.*;import java.sql.*;import javax.servlet.*;public class saveregister extends HttpServlet public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException this.doPost(request,response);
