图片如何存进mysql数据库

// 读取图片文件
File file = new File("path/to/image.jpg");
byte[] imageData = new byte[(int) file.length()];

try (FileInputStream fis = new FileInputStream(file)) {
    fis.read(imageData);
} catch (IOException e) {
    e.printStackTrace();
}

// 将图片数据存储到MySQL数据库中
String sql = "INSERT INTO images (image_data) VALUES (?)";
try (Connection conn = DriverManager.getConnection(url, username, password);
     PreparedStatement pstmt = conn.prepareStatement(sql)) {
    pstmt.setBytes(1, imageData);
    pstmt.executeUpdate();
} catch (SQLException e) {
    e.printStackTrace();
}

// 保存图片文件到服务器目录
String imagePath = "path/to/image.jpg";
File file = new File(imagePath);
// ...

// 将图片路径存储到MySQL数据库中
String sql = "INSERT INTO images (image_path) VALUES (?)";
try (Connection conn = DriverManager.getConnection(url, username, password);
     PreparedStatement pstmt = conn.prepareStatement(sql)) {
    pstmt.setString(1, imagePath);
    pstmt.executeUpdate();
} catch (SQLException e) {
    e.printStackTrace();
