How to enum mapping with jpa Spring boot why not save enum value in DB in DB saving enum key when i saving product in databse not save status like Active it always save ACTIVE

You just need to pay attention to the enum values when the table is being created.
What are the enum values in the table e.g. in status column, are the values defined as 'Active', 'Inactive' or 'ACTIVE', 'INACTIVE'. That's what will determine the value saved.
If the enum values are defined as 'ACTIVE', 'INACTIVE', if you insert 'active' as the value for status, it will change to 'ACTIVE' inside the database because it inserts based on the pre defined enum values.

booking.getSlot() and booking.getSubscriber() returns null
Please let me know if i miss some configuration while mapping
EDIT1
Added code how the entity is getting loaded
public Booking addBooking(String title,String desc,int slotid,int subscriberid,Session session){
Booking booking = new Booking();
booking.setTitle(title);
booking.setDesc(desc);
booking.setSlotid(slotid);
booking.setSubscriberid(subscriberid);
booking.setCreated(new Date());
Integer bookingid = (Integer) session.save(booking);
session.flush();
Booking bookingEntity = (Booking) session.createQuery("From Booking where id = ?").
setParameter(0, bookingid).list().get(0);
return bookingEntity;
}
I am saving the entity and reloading it.

It's not working because Hibernate is retuning the same instance it has already in its 1st level cache, which doesn't have a reference to any of the 2 other entities.
To fix this, you have to do a session.refresh(booking) rather than executing a query.

In your code :
booking.setSlotid(slotid);
booking.setSubscriberid(subscriberid);
You're just setting Integer values and not objects. Instead of this, try to set objects :
booking.setSlot(new Slot(slotid));
booking.setSubscriber(new Subscriber(subscriberid));
But as #Augusto said, the associations you're having in the session (Slot and Subscriber) are not full objects they contain only their ids. That's why you can't get other fields of these objects.

Now I am using Primefaces datatable to show a List<Activity> in which I have filtering on the field name of ActivityType. ActivityType is associated with Activity by #ManyToOne relationship.
For filtering the List<Activity> I am using:
Criteria criteria = getSessionFactory().getCurrentSession().createCriteria(Activity.class);
criteria.createCriteria("activityType").add(Restrictions.like("name", value.toString(), MatchMode.START));
I am getting:
null: org.hibernate.QueryException: duplicate association path: activityType
at org.hibernate.loader.criteria.CriteriaQueryTranslator.createAssociationPathCriteriaMap(CriteriaQueryTranslator.java:172) [hibernate-core-4.1.8.Final.jar:4.1.8.Final]

at com.edfx.adb.dao.ActivityDao.loadActivities(ActivityDao.java:54) [classes:]
at com.edfx.adb.service.ActivityService.loadActivities(ActivityService.java:101) [classes:]
This error is not showing always and never after the first load. After filtering the table for 5-6 time, I am having this error.
I am worried that if the mapping and the criteria is right or not. Any suggestion would be very helpful.

I think you need to provide an alias, so you should change your code this way:
Criteria criteria = getSessionFactory().getCurrentSession().createCriteria(Activity.class);
criteria.createCriteria("activityType", "at")
.add(
Restrictions.like("at.name", value.toString(), MatchMode.START));
