You could start with a generic DAO pattern that is just a thin wrapper around an entity manager, something like the following:
| public interface GenericDao | { | public <T extends BaseEntity> void save (T entity); | | public <T extends BaseEntity> void delete (T entity); | | public <T extends BaseEntity> void delete (Class<T> clazz, Serializable id) ; | | public <T extends BaseEntity> T find (Class<T> clazz, Serializable id) ; | | public <T extends BaseEntity> List<T> list (Class<T> clazz) ; | | public <T extends BaseEntity> T findByExample (T example); | | public <T extends BaseEntity> List<T> listByExample (T example); | } | Then you'd still have the option to switch your persistence layer should the need arise.
