Interface ICustomerDao

All Superinterfaces:

IBaseDao<Long,Customer>, IBaseReadOnlyDao<Long,Customer>, IGenericDao<Long,Customer>, IGenericReadOnlyDao<Long,Customer>

public interface ICustomerDao
extends IGenericDao<Long,Customer>

Abstract definition of the Customer DAO. This definition was introduced to support the Spring Generic DAO example implementation.

Note that this interface is all the Java code needed to provide such custom finder capability. The SpringGenericDao implementation will take care of the rest that includes all the plumbing to Hibernate. At this point it is only required the appropriate Hibernate mapping.
