如何把图片保存的mysql数据库

import java.io.File;
import java.io.FileInputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;

public class SaveImageToDatabase {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/database_name";
        String username = "username";
        String password = "password";

        try {
            // 加载MySQL数据库驱动
            Class.forName("com.mysql.jdbc.Driver");

            // 建立数据库连接
            Connection connection = DriverManager.getConnection(url, username, password);

            // 创建预处理语句
            String sql = "INSERT INTO images (name, data) VALUES (?, ?)";
            PreparedStatement statement = connection.prepareStatement(sql);

            // 准备图片
            File imageFile = new File("path_to_image");
            FileInputStream fileInputStream = new FileInputStream(imageFile);

            // 设置参数
            statement.setString(1, imageFile.getName());
            statement.setBinaryStream(2, fileInputStream, (int) imageFile.length());

            // 执行插入操作
            statement.executeUpdate();

            // 关闭连接
            statement.close();
            connection.close();

            System.out.println("图片保存成功！");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
