 * To simplify the creation of Data Repositories a generic Repository interface and base class is provided.  Furthermore, Spring will automatically create a Repository implementation for you that add implementations of finder methods you specify on an interface.  For example the Repository interface is
 
-public interface Repository<T, ID extends Serializable> {
+    public interface Repository<T, ID extends Serializable> {
 
-    T save(T entity);
+        T save(T entity);
 
-    List<T> save(Iterable<? extends T> entities);
+	List<T> save(Iterable<? extends T> entities);
 
-    T findById(ID id);
+	T findById(ID id);
 
-    boolean exists(ID id);
+	boolean exists(ID id);
 
-    List<T> findAll();
+	List<T> findAll();
 
-    Long count();
+	Long count();
 
-    void delete(T entity);
+	void delete(T entity);
 
-    void delete(Iterable<? extends T> entities);
+	void delete(Iterable<? extends T> entities);
 
-    void deleteAll();
-}

 and there is a placeholder interface called MongoRepository that will in future add more Mongo specific methods.
