Question

将InputStream转换为BufferedImage时，我收到以下错误

byte[] imgBytes = decoder.decode(encodedStr);

这一行正常运行并正确生成字节数组

InputStream in = new ByteArrayInputStream(imgBytes);
BufferedImage  bImageFromConvert = ImageIO.read(in);

由于无法正确阅读InputStream

，此行会出错

之前可能发生错误。在Java中，字符串encodedStr通常不适合保存二进制数据。将imgBytes与原始图片进行比较。

当然这取决于编码和解码。但其余的看起来还不错。
