import com.sun.image.codec.jpeg.*;
import java.awt.image.BufferedImage;
import java.io.*;public class SunJPEGEncoderAdapter
    implements ImageEncoder
{    public SunJPEGEncoderAdapter()
    {
        quality = 0.75F;
    }    public byte[] encode(BufferedImage bufferedImage)
        throws IOException
    {
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        encode(bufferedImage, ((OutputStream) (outputStream)));
        return outputStream.toByteArray();
    }    public void encode(BufferedImage bufferedImage, OutputStream outputStream)
        throws IOException
    {
        if(bufferedImage == null)
            throw new IllegalArgumentException("Null 'image' argument.");
        if(outputStream == null)
        {
            throw new IllegalArgumentException("Null 'outputStream' argument.");
        } else
        {
            JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(outputStream);
            JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bufferedImage);
            param.setQuality(quality, true);
            encoder.encode(bufferedImage, param);
            return;
        }
    }
}
希望这段代码对你有帮助
