The implementation of the method findByExample(T exampleInstance,
String[] excludeProperty) in GenericHibernateDAO class is different from
its definition in the interface GenericDAO. 

I tried to create a ItemDAO interface and ItemDAOHibernate class and got
the error
"The type ItemDAOHibernate must implement the inherited abstract method 
 GenericDAO<Item,Long>.findByExample(Item)"

Should you add the parameter to the interface GenericDAO or remove the
parameter from the GenericHibernateDAO class?
