hibernate的getRow在哪

hibernate的映射实现得真复杂

在Loader中有一个getRow就是完成结果映射的

private Object[] getRow(
			final ResultSet rs,
			final Loadable[] persisters,
			final EntityKey[] keys,
			final Object optionalObject,
			final EntityKey optionalObjectKey,
			final LockMode[] lockModes,
			final List hydratedObjects,
			final SharedSessionContractImplementor session) throws HibernateException, SQLException {
		final int cols = persisters.length;
		final EntityAliases[] descriptors = getEntityAliases();

		if ( LOG.isDebugEnabled() ) {
			LOG.debugf( "Result row: %s", StringHelper.toString( keys ) );
		}

		final Object[] rowResults = new Object[cols];

		for ( int i = 0; i < cols; i++ ) {

			Object object = null;
			EntityKey key = keys[i];

			if ( keys[i] == null ) {
				//do nothing
			}
			else {
				//If the object is already loaded, return the loaded one
				object = session.getEntityUsingInterceptor( key );
				if ( object != null ) {
					//its already loaded so don't need to hydrate it
					instanceAlreadyLoaded(
							rs,
							i,
							persisters[i],
							key,
							object,
							lockModes[i],
							session
					);
				}
				else {
					object = instanceNotYetLoaded(
							rs,
							i,
							persisters[i],
							descriptors[i].getRowIdAlias(),
							key,
							lockModes[i],
							optionalObjectKey,
							optionalObject,
							hydratedObjects,
							session
					);
				}
			}

			rowResults[i] = object;

		}

		return rowResults;
	}

真是复杂，spring-jdbc还简单一点，不知道为啥
