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">&nbsp;&nbsp;&nbsp;
 <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 language="java" import="java.sql.*" pageencoding="utf-8"%>
<%@ 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>
 </head>
 <body>
 请选择查询条件<hr width="100%" size="3">
 <form action="stufind3.jsp" method="post">
 性别<input type="radio" value="男" name="sex" checked="checked">男
 <input type="radio" value="女" name="sex">女
 年龄范围：<p>&nbsp;&nbsp;
 最小：<input type="text" name="a1"><br><br>&nbsp;
 最大：<input type="text" name="a2"><p>
 <input type="submit" value="提交">
 <input type="reset" value="取消">
 </form>
 </body>
</html>

<%@ page contenttype="text/html" import="java.sql.*" pageencoding="utf-8"%>
<html>
 <head>
 <title>条件查询处理页面</title>
 </head>
 <body>
 <center>
 <%class.forname("com.microsoft.sqlserver.jdbc.sqlserverdriver");
 string user="sa";
 string password="123456";
 string url="jdbc:sqlserver://localhost:1433;databasename=p";
 connection conn=drivermanager.getconnection(url,user,password);
 request.setcharacterencoding("utf-8");
 string sex=request.getparameter("sex");
 int age1=integer.parseint(request.getparameter("a1"));
 int age2=integer.parseint(request.getparameter("a2"));
 string sql="select * from student where ssex=? and sage>=? and sage<=?";
 preparedstatement pstmt=conn.preparestatement(sql);
 pstmt.setstring(1,sex);
 pstmt.setint(2,age1);
 pstmt.setint(3,age2);
 resultset rs=pstmt.executequery();
 %>
 <table border="2" bgcolor="ccceee" width="650">
 <tr bgcolcor="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>
 <%}%>
 </table>
 <%if(rs!=null){rs.close();}
  if(pstmt!=null){pstmt.close();}
  if(conn!=null){conn.close();}
 %>
 </center>
 </body>
</html>

3.修改模块

<%@ page language="java" import="java.util.*" pageencoding="utf-8"%>
<html>
 <head> 
 <title>修改提交页面</title>
 </head>
 <body>
 <center>
  请选择修改记录所满足的条件
 <form action="stuupdate2.jsp" method="post">

  string name=request.getparameter("name");
  string sex=request.getparameter("sex");
  session.setattribute("sex",sex);
  session.setattribute("name",name);
  string sql="select * from student where ssex=? and sname=?";
  preparedstatement pstmt=conn.preparestatement(sql);
  pstmt.setstring(1,sex);
  pstmt.setstring(2,name);
  resultset rs=pstmt.executequery();
  if(rs.next()){
  string id=rs.getstring("sno");
  string name2=rs.getstring("sname");
  string sex2=rs.getstring("ssex");
  int age=rs.getint("sage");
  string sdept=rs.getstring("sdept");
  if(pstmt!=null){pstmt.close();}
  if(rs!=null){rs.close();}
  if(conn!=null){conn.close();}
  %>
  <form action="stuupdate3.jsp" method="post">

 </body>
</html>

<%@ page language="java" import="java.sql.*" pageencoding="utf-8"%>
<html>
 <head> 
 <title>修改后重写页面</title>

  </form>
 </body>
</html>


<%@ page language="java" import="java.sql.*" pageencoding="utf-8"%>
<html>
 <head> 
 <title>条件删除处理页面</title>
 </head> 
 <body>
 <% class.forname("com.microsoft.sqlserver.jdbc.sqlserverdriver");
  string user="sa";
  string password="123456";
  string url="jdbc:sqlserver://localhost:1433;databasename=p";
  connection conn=drivermanager.getconnection(url,user,password);
  request.setcharacterencoding("utf-8");
  string name=request.getparameter("name");
  string sex=request.getparameter("sex");
  string ag1=request.getparameter("a1");
  string ag2=request.getparameter("a2");
  int a3,a4;
  string sql="delete from student where sname=? and ssex=? and sage>=? and sage<=?";
  preparedstatement pstmt=conn.preparestatement(sql);
  if(!name.equals("")) pstmt.setstring(1,name);
  if(sex!=null) pstmt.setstring(2,sex);
  if(!ag1.equals("")){a3=integer.parseint(ag1); pstmt.setint(3,a3);}
  if(!ag2.equals("")){a4=integer.parseint(ag2); pstmt.setint(4,a4);}
  int n=pstmt.executeupdate();
  if(n==1){%>数据删除成功<br><%}
  else{%>数据删除失败！<br><%}
  if(pstmt!=null){pstmt.close();}
  if(conn!=null){conn.close();}
 %>
 </body>
</html>
