以下是我将其转换为byte[]的方式：
byte[] imageByte = Base64.decode(str);
以下是我想将它保存在我的机器上的方法：
BufferedImage image = null;
String path = EVENT_FOLDER + name + "." + extension;
try
{
image = ImageIO.read(new ByteArrayInputStream(imageByte));
ImageIO.write(image, extension, new File(path));
}
catch (IOException e)
{
e.printStackTrace();
}
我得到了这个例外：

这个错误说的是什么？我如何解决它？谢谢！
答案 0 :(得分：1)
我打赌问题是你使用的工具实际上并没有转换原始文件，而是编码图像数据本身。这意味着输入不适合ImageIO。
