The session = sqlSessionFactory.openSession the SqlSession (ExecutorType.BATCH, to false); 
commericalModelMapper = session.getMapper (CommericalModelMapper.class); 

commericalModelMapper.insert (commericalModel); 
when the added use, introduced in batches, can be included in that line is wrong returns; successfully added the number of rows can be processed
