net.coobird.thumbnailator.tasks.UnsupportedFormatException: No suitable ImageReader found for source data. at net.coobird.thumbnailator.tasks.io.InputStreamImageSource.read(Unknown Source) at net.coobird.thumbnailator.tasks.SourceSinkThumbnailTask.read(Unknown Source) at net.coobird.thumbnailator.Thumbnailator.createThumbnail(Unknown Source) at net.coobird.thumbnailator.Thumbnails$Builder.toOutputStream(Unknown Source)
处理代码如下：
Blob zp = rs.getBlob("swry_zp");
if(zp!=null){
is=zp.getBinaryStream();
if (null != is) {
baos = new ByteArrayOutputStream();
//对图片进行压缩处理
Thumbnails.of(is).forceSize(98, 137).toOutputStream(baos);
//将照片进行Base64转码
sy.setSwry_zp(Base64.encodeBase64String(baos.toByteArray()));
}
}从oracle中读出照片信息，照片以blog格式存储，然后以Base64编码返回给客户端，以上错误信息只是在获取某些照片信息时报错，有些照片
这种方式处理是没有问题的．当前是：
Thumbnails.of(is).forceSize(98, 137).toOutputStream(baos);
抛出IO异常，然后rs就中断了：
while(rs.next()){}其源码中抛出此异常的代码段如下：
public BufferedImage read() throws IOException { ImageInputStream iis = ImageIO.createImageInputStream(is); if (iis == null) { throw new IOException("Could not open InputStream."); } Iterator<ImageReader> readers = ImageIO.getImageReaders(iis); if (!readers.hasNext()) { throw new UnsupportedFormatException( UnsupportedFormatException.UNKNOWN, "No suitable ImageReader found for source data." ); } ImageReader reader = readers.next(); reader.setInput(iis); inputFormatName = reader.getFormatName(); BufferedImage img = reader.read(FIRST_IMAGE_INDEX); iis.close(); return img; }
具体原因还没有找出，
