re-install grub using Fedora Live CD. Fedora was installed with LVM. The system dual boots Ubuntu and Fedora.
su
mkdir /mnt/root
# You may use fdisk -l to list the devices
mount /dev/mapper/fedora-root /mnt/root
# Mount the boot partition, maybe /dev/sda1
# As the system has both Ubuntu and Fedora installed,
# so sda3 in my case
mount /dev/sda<3> /mnt/root/boot

How to get Path Variables inside a Spring interceptor.[This post assumes that you have an Interceptor registered and set up using XML or Java config]
public class SomeInterceptor extends HandlerInterceptorAdapter{
@Override
public boolean preHandle(final HttpServletRequest request,final HttpServletResponse response,final Object handler)
throws Exception
{
/*Assume the URI is user/{userId}/post/{postId} and our interceptor is registered for this URI.
* This map would then be a map of two elements,with keys 'userId' and 'postId'
*/
final Map<String, String> pathVariables = (Map<String, String>) request
.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE);
