Question

以下代码适用于以前的版本，但在升级到Java 7后无法正常工作。

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。

ImageIO.createImageInputStream无法在java平台上运行
