java利用jdbc向数据库存入二进制图片数据

1、新建数据库

CREATE TABLE `photo` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(20) DEFAULT NULL COMMENT '姓名',
  `photo` longblob COMMENT '照片',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

2、插入二进制图片数据：

package com.lemon.photo;

//存入图片
import java.sql.*;
import java.io.*;
public class InsertImg
{
    public static void main(String args[])
    {
        try{
            Class.forName("com.mysql.jdbc.Driver");
            String url="jdbc:mysql://localhost:3306/tbtest";
            Connection cn=DriverManager.getConnection(url,"root","123456");
           // Statement st=cn.createStatement();
            String sql = "insert into photo (id,name,photo) values (null,'测试',?)";
            PreparedStatement statement=cn.prepareStatement(sql);
            FileInputStream inputStream=new FileInputStream("d://timg.jpg");
            statement.setBinaryStream(1,inputStream,inputStream.available());
            statement.execute();
            inputStream.close();
            statement.close();
            cn.close();
        }catch(Exception e){System.out.println(e.getMessage());}
    }
}
