错误意外结束

虽然转换InputStream到BufferedImage我得到下面的错误错误意外结束

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

这条线被执行细并生成字节数组正确

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

这条线是给出错误，因为它无法正确读取InputStream

Below is the error

是否有可能您的解码方法错误或** encodedStr **损坏？ – 2013-04-30 08:49:23

什么是'解码器'？你在这里给我们提供了很少的信息。 – 2013-04-30 08:51:41

错误可能发生在之前。在Java中，字符串encodedStr通常不适合保存二进制数据。将这些imgBytes与原始图像进行比较。

当然，这取决于编码和解码。但其余的看起来没问题。
