JSP学生信息管理系统设计
本文实例为大家分享了JSP学生信息管理系统源码，供大家参考，具体内容如下
新建学生信息数据库
1.添加记录模块
<%@ page contentType="text/html" pageEncoding="UTF-8"%>
<html>
<head>
<title>添加新学生</title>
</head>
<body>
<form action="stuinsert2.jsp" method="post">
<table border="0" width="238" heigth="252">
<tr><td>学号：</td><td><input type="text" name="id"></td></tr>
<tr><td>姓名</td><td><input type="text" name="name"></td></tr>
<tr><td>性别</td><td><input type="text" name="sex"></td></tr>
<tr><td>年龄</td><td><input type="text" name="age"></td></tr>
<tr><td>专业</td><td><input type="text" name="sdept"></td></tr>
<tr align="center">
<td colspan="2">
<input type="submit" value="提交">
<input type="reset" value="取消">
</td>
</tr>
</table>
</form>
</body>
</html>
<%@ page language="java" import="java.sql.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>添加学生处理程序</title>
</head>
<body>
<% Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url="jdbc:sqlserver://localhost:1433; DatabaseName=p";
String user="sa";
String password="123456";
Connection conn=DriverManager.getConnection(url,user,password);
request.setCharacterEncoding("UTF-8");
String id=request.getParameter("id");
String name=request.getParameter("name");
String sex=request.getParameter("sex");
int age=Integer.parseInt(request.getParameter("age"));
String sdept=request.getParameter("sdept");
String sql=String.format("select * from student where Sno=%s",id);
Statement stmt=conn.createStatement();
PreparedStatement pstmt;
ResultSet rs=stmt.executeQuery(sql);
if(!(rs.next())){
pstmt=conn.prepareStatement("insert into Student values(?,?,?,?,?)");
pstmt.setString(1,id);
pstmt.setString(2,name);
pstmt.setString(3,sex);
pstmt.setInt(4,age);
pstmt.setString(5,sdept);
pstmt.executeUpdate();
out.print("添加成功");
%>
<a href="stuinsert.jsp" rel="external nofollow" rel="external nofollow" >返回菜单</a><br>
<a href="main.jsp" rel="external nofollow" ></a>
<%}else{
out.println("该学号已存在");%>
<a href="stuinsert.jsp" rel="external nofollow" rel="external nofollow" >重新添加</a>
<%}%>
</body>
</html>
2.查询(all)模块

<%@ page import="javax.sql.*" %>
<%@ page import="javax.naming.*" %>
<html>
<head>
<title>信息查看页面</title>
</head>
<body>
<center>
<% DataSource ds=null;
InitialContext ctx=new InitialContext();
ds=(DataSource)ctx.lookup("java:comp/env/jdbc/sqlserver");
Connection conn=ds.getConnection();
PreparedStatement pstmt=conn.prepareStatement("select * from Student");
ResultSet rs=pstmt.executeQuery();
%>
<table border="2" bgcolor="ccceee" width="650">
<tr bgcolor="CCCCCC" align="center">
<td>记录条数</td><td>学号</td><td>姓名</td>
<td>性别</td><td>年龄</td><td>专业</td>
</tr>
<%
while(rs.next()){
%>
<tr align="center">
<td><%=rs.getRow()%></td>
<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>
</tr>
<%}%>
</center>
<%if(rs!=null){rs.close();}
if(pstmt!=null){pstmt.close();}
if(conn!=null){conn.close();}
%>
</table>
</body>
</html>
条件查询模块
<%@ page language="java" pageEncoding="UTF-8"%>
<html>
<head>
<title>My JSP 'stufind2.jsp' starting page</title>
