Springboot模式下Mybatis的batch模式怎么写

public int addUserSpace(List<UserSpace> userSpaceList) {

        SqlSessionFactory sqlSessionFactory = sqlSessionTemplate.getSqlSessionFactory();
        SqlSession sqlSession = sqlSessionFactory.openSession(ExecutorType.BATCH,false );

        UserSpaceMapper mapper = sqlSession.getMapper(UserSpaceMapper.class);

        for (UserSpace userSpace : userSpaceList) {
            UserSpaceEntity userSpaceEntity = userSpaceConverter.to(userSpace);
            mapper.insert(userSpaceEntity);
        }
        //进行批次提交
        sqlSession.commit();
        //清除缓存
        sqlSession.clearCache();
        //关闭连接
        sqlSession.close();

        return 0;
    }

还有个注意点
