java - ImageIO.createImageInputStream 无法在 Java 平台 se 7 上运行

Question

下面的代码在以前的版本中运行良好，但在升级到 Java 7 后无法运行。

有人可以帮忙吗？

代码:

if (imageFile.exists())

System.out.println(imageFile.getPath()+" :"+ imageFile.getName());
      // prepare to read the input

final FileInputStream fis = new FileInputStream (imageFile);  

ImageInputStreamiis=null;
iis = ImageIO.createImageInputStream(fis);          
final Iterator<ImageReader> imageReaders = ImageIO.getImageReaders(iis);
ImageReader reader = imageReaders.next();
reader.setInput(iis, true, false);

Answer 1

我在这里回答了一个基本相同的问题:ImageIO methods not working after switching to Java 7 .

唯一的区别是，此异常是由 ImageInputStreamSpi 尝试注册为 ImageReaderSpi 引起的。
