MultipartFile转ImageInfo

A：

要将MultipartFile转换为ImageInfo，可以按照以下步骤进行操作：

1. 获取MultipartFile的输入流

InputStream inputStream = file.getInputStream();

2. 将输入流转换为BufferedImage

BufferedImage image = ImageIO.read(inputStream);

3. 创建ImageInfo对象

ImageInfo imageInfo = new ImageInfo();
imageInfo.setWidth(image.getWidth());
imageInfo.setHeight(image.getHeight());
imageInfo.setType(file.getContentType());
imageInfo.setData(image.getData());

完整代码片段：

InputStream inputStream = file.getInputStream();
BufferedImage image = ImageIO.read(inputStream);

ImageInfo imageInfo = new ImageInfo();
imageInfo.setWidth(image.getWidth());
imageInfo.setHeight(image.getHeight());
imageInfo.setType(file.getContentType());
imageInfo.setData(image.getData());

注意：需要导入java.awt.image.BufferedImage和javax.imageio.ImageIO库。
