Hello Guys,
Here I will suggest you the best coding standard to develop effective and fast application in java technology. So, now I am writing code for changing image orientation while uploading image from mobile.
For this follow below steps -
step 1.
Import below .jar file.
imgscalr-lib-4.2.jar
metadata-extractor-2.6.2.jar

step 2.

InputStream  in = new BufferedInputStream(uploadRequest.getFileAsStream(parameterName));
BufferedImage sourceImage = ImageIO.read(in);  
//Invoke getEXIFOrientation method
Rotation rotate=getEXIFOrientation(IOUtils.toByteArray(uploadRequest.getFileAsStream(parameterName)));
        if(ratate != null){
                    //Rotate to image
        sourceImage = Scalr.rotate(sourceImage,rotate , Scalr.OP_ANTIALIAS);
        }

//Note : "sourceImage" to change according requirement

private static Rotation getEXIFOrientation(byte[] bytes) {
int orientation = 1; // default = unknown
 ByteArrayInputStream bis = null;
 try {
 bis = new ByteArrayInputStream(bytes);
 Metadata metadata = ImageMetadataReader.readMetadata(new BufferedInputStream(bis), false);
 ExifIFD0Directory exifDir = metadata.getDirectory(ExifIFD0Directory.class);
 if (exifDir != null) {
 orientation = exifDir.getInt(ExifIFD0Directory.TAG_ORIENTATION); // 274 is the EXIF orientation standard code
 }
 } catch (Exception e) {
 System.out.println("Couldn't extract EXIF orientation from image");
 } finally {
 if (bis != null) try {
 bis.close();
 } catch (IOException e) {
 // nothing
 }
 }

switch (orientation) {
  case 1: // [Exif IFD0] Orientation - Top, left side (Horizontal / normal)
    return null;
  case 6: // [Exif IFD0] Orientation - Right side, top (Rotate 90 CW)
    return Rotation.CW_90;
  case 3: // [Exif IFD0] Orientation - Bottom, right side (Rotate 180)
    return Rotation.CW_180;
  case 8: // [Exif IFD0] Orientation - Left side, bottom (Rotate 270 CW)
    return Rotation.CW_270;
}
 return null;
}    

Thank you
