mybatis use batch operations to achieve sqlSessionFactory

sqlSessionFactory achieve java batch submitted, but can not return the number of affected.

 1 public int updateBatch(List<Object> list){
 2         if(list ==null || list.size() <= 0){
 3             return -1;
 4         }
 5         SqlSessionFactory sqlSessionFactory = SpringContextUtil.getBean("sqlSessionFactory");
 6         SqlSession sqlSession = null;
 7         try {
 8             sqlSession = sqlSessionFactory.openSession(ExecutorType.BATCH,false);
 9             Mapper mapper = sqlSession.getMapper(Mapper.class);
 10              int batchCount = 1000; // number of submissions, the number of arriving submitted 
. 11              for ( int index = 0; index <list.size (); index ++ ) {
 12 is                  Object obj = List.get (index);
 13 is                  Mapper .updateInfo (obj);
 14                  IF (index = 0 == 0 && index batchCount%! ) {
 15                      sqlSession.commit ();
 16                  }                    
 . 17              }
 18 is              sqlSession.commit ();
 . 19              return 0 ;
 20 is          }catch (Exception e){
21             sqlSession.rollback();
22             return -2;
