JSP实现MYSQL5.1存入图片
connection.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ page import="java.sql.*" errorPage="" %><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><p><table border="1"> <tr> <td>图片Num</td> <td>图片</td> </tr> <% Connection conn = null; Statement stmt = null; ResultSet rs = null; request.setCharacterEncoding("utf-8"); String uri = "jdbc:mysql://localhost:3306/test";//使用的是test数据库 String sql = "select picNum from pic "; //我建图片表 pic try{ Class.forName("com.mysql.jdbc.Driver"); }catch(Exception e){ out.print(e); } try{ conn = DriverManager.getConnection(uri,"root","root");//我的用户名是 root ,密码 是 soft 根据你的需要 更改 stmt = conn.createStatement(); rs = stmt.executeQuery(sql); while(rs.next()){%> <tr> <td><%=rs.getString("picNum")%></td> <td><img src="tupian/<%=rs.getString("picNum")%>"></td> </tr> <% } }catch(Exception e){ out.print(e); }%></table></body></html>数据库的设计：
附录：sql脚本use test;create table pic( id int primary key auto_increment, picNum varchar(10) unique);
然后插入数据：
insert into pic(picNum) values('1.jpg');insert into pic(picNum) values('2.jpg');insert into pic(picNum) values('3.jpg');insert into pic(picNum) values('4.jpg');insert into pic(picNum) values('5.jpg');insert into pic(picNum) values('6.jpg');insert into pic(picNum) values('7.jpg'); 结果图：
