本文实例讲述了jsp+mysql数据库操作常用方法。分享给大家供大家参考。具体如下：

1. 查看：

<%@ page contentType="text/html;charset=GB2312" %> <%@ page import="java.sql.*" %> <HTML><style type="text/css">  </style> <BODY> <font color="#FFFFFF"> <center> <% Connection con; Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","123456"); Statement sql; ResultSet rs; try { sql=con.createStatement(); rs=sql.executeQuery("SELECT * FROM student"); out.print("<Table Border>"); out.print("<TR><td colspan=5 align=center>考生数据</td></tr>"); out.print("<TR><td colspan=5 align=center><a href='add.jsp' target='_self'>添加考生信息</a></td></tr>"); out.print("<TR>"); out.print("<Td width=50 >"+"姓名"); out.print("<Td width=100 >"+"年龄"); out.print("<Td width=100>"+"出生日期"); out.print("<Td width=100 colspan=2>"+"操作"); out.print("</TR>"); while(rs.next()) { out.print("<TR>"); out.print("<TD >"+rs.getString(2)+"</TD>"); out.print("<TD >"+rs.getString(3)+"</TD>"); out.print("<TD >"+rs.getString(4)+"</TD>"); String idstr=rs.getString(1); out.print("<TD><a href='delete.jsp"'>删除</a></TD>"); out.print("<TD><a href='update.jsp"'>修改</a></TD>"); out.print("</TR>") ; } out.print("</Table>"); con.close(); } catch(SQLException e1) { out.print("SQL异常！！！！"); } %> </center> </BODY> </HTML>

2. add 添加：

<%@ page contentType="text/html;charset=gb2312" %> <HTML><HEAD> <style type="text/css">  </style> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"></HEAD> <BODY> <Font size=2> <p align="center">添加考生信息</p> <CENTER> <FORM action="insert.jsp" name=form> <table> <tr><td height="36"><span>姓名:</span></td> <td><Input name="name" type=text size="15" ></td></tr> <tr> <td height="36"><span>年龄:</span></td> <td><Input name="age" type=text size="15"></td></tr> <tr> <td height="36"><span>出生年月:</span></td> <td><Input name="birth" type=text size="15"></td></tr> </table> <table width="165"> <tr><td width="42" wnameth="42"><Input type=submit name="g" value="添加"></td> <td width="28" wnameth="50"></td> <td width="42" wnameth="50"><Input type="reset" name="h" value="重置"></td> <td width="33" wnameth="42"></td> </tr> </table> </Form></CENTER> </Body></HTML>

3. delete 删除：

<%@ page contentType="text/html;charset=gb2312" %> <%@ page import="java.sql.*" %> <html> <head> <title>删除操作</title> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"><style type="text/css">  </style></head> <body> <center> <% Connection con; Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","123456"); Statement stmt; Statement s; ResultSet rs; String id=request.getParameter("id"); try { stmt=con.createStatement(); String sql="delete from student where id="+id; stmt.executeUpdate(sql); s=con.createStatement(); rs=s.executeQuery("SELECT * FROM student"); out.print("<Table Border>"); out.print("<TR><td colspan=5 align=center>考生数据</td></tr>"); out.print("<TR><td colspan=5 align=center><a href='add.jsp' target='_self'>添加考生信息</a></td></tr>"); out.print("<TR>"); out.print("<Td width=50 >"+"姓名"); out.print("<Td width=100 >"+"年龄"); out.print("<Td width=100>"+"出生日期"); out.print("<Td width=100 colspan=2>"+"操作"); out.print("</TR>"); while(rs.next()) { out.print("<TR>"); out.print("<TD >"+rs.getString(2)+"</TD>"); out.print("<TD >"+rs.getString(3)+"</TD>"); out.print("<TD >"+rs.getString(4)+"</TD>"); String idstr=rs.getString(1); out.print("<TD >"+idstr+"</TD>"); out.print("<TD><a href='delete.jsp"'>删除</a></TD>"); out.print("<TD><a href='update.jsp"'>修改</a></TD>"); out.print("</TR>") ; } out.print("</Table>"); con.close(); } catch(SQLException e1) { out.print("SQL异常！！！！"); } %> </center> </body> </html>

4. update 示例1：

<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>无标题文档</title> <style type="text/css">  </style></head> <body> <%String id=request.getParameter("id"); Connection con; String name=null; String age=null; String birth=null; String id1=null; Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","123456"); Statement sql; ResultSet rs; try { sql=con.createStatement(); rs=sql.executeQuery("SELECT * FROM student"); while(rs.next()) { name=rs.getString(2); age=rs.getString(3); birth=rs.getString(4); id1=rs.getString(1); } con.close(); } catch(SQLException e1) { out.print("SQL异常！！！！"); } %> <center> <form action="update2.jsp"> <center> <p> </p> <p>姓名： <input name="name" type="text" size="15" value="<%=name%>"> </p> <p> 年龄： <input name="age" type="text" size="15" value="<%=age%>"> </p> <p>出生日期： <input name="birth" type="text" size="15" value="<%=birth%>"> <input name="id1" type="hidden" value="<%=id1%>" /> </p> <p><input name="g" type="submit" value="修改"> <input name="h" type="reset" value="重置"></p> </form> </center> </body> </html>

5. update 示例2：

<%@ page contentType="text/html;charset=gb2312" %> <%@ page import="java.sql.*" %> <% String name=request.getParameter("name"); String age=request.getParameter("age"); String birth=request.getParameter("birth"); String id1=request.getParameter("id1"); System.out.println(id1); Connection con=null; try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","123456"); Statement sql; sql=con.createStatement(); String sql2="update student set name='"+name+"',age='"+age+"',birth='"+birth+"' where id="+id1; System.out.print(sql2); int s=sql.executeUpdate(sql2); } catch(Exception e){ System.out.println(e); } %> 恭喜你，修改成功！<br /> <a href="chakan.jsp">查看</a>

6. insert 插入

<%@ page contentType="text/html;charset=gb2312" %> <%@ page import="java.sql.*" %> <% String name=request.getParameter("name"); String age=request.getParameter("age"); String birth=request.getParameter("birth"); Connection con=null; try { Class.forName("com.mysql.jdbc.Driver"); con = DriverManager.getConnection("jdbc:mysql://localhost:3306/student","root","123456"); Statement sql; sql=con.createStatement(); String sql2="insert into student(name,age,birth) values('"+name+"','"+age+"','"+birth+"')"; System.out.print(sql2); int s=sql.executeUpdate(sql2); } catch(Exception e){ System.out.println(e); } %> 恭喜你，添加成功！<br /> <a href="chakan.jsp">查看</a>

7. 创建数据库

/* MySQL Data Transfer Source Host: localhost Source Database: student Target Host: localhost Target Database: student Date: 2009-3-27 13:24:01 */ SET FOREIGN_KEY_CHECKS=0; create database student; use student; -- ---------------------------- -- Table structure for student -- ---------------------------- CREATE TABLE `student` ( `id` int(11) NOT NULL auto_increment, `name` varchar(255) default NULL, `age` varchar(255) default NULL, `birth` varchar(255) default NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=gbk;
