In our project, we have an entity 'Restaurant' with nearly 30 fields(some have relationships with other entities). So, every time we need a 'Restaurant' object even for a few fields, all the others are retrieved. This effects the performance. So, in the hbm file we wrote two classes both pointing to the same physical class and same table in database as shown below.
In one of the DAO implementations, we are using Criteria which takes 'RestaurantLite' and returning list of restaurants as we have to work with only restaurant objects as shown below.
Now we want to remove all hbm files and use annotations. So how the same can be done using annotations for entites? Do we need to create an extra class 'RestaurantLite'? If then, how the above criteria returns 'Restaurant' objects??
