insert/update always return negative update/affected counts when ExecutoryType is BATCH

[rigofunc]

If create SqlSessionTemplate bean with ExecutorType.BATCH, the insert/delete/update always return negative update/affected counts

@Bean
    public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(dataSource);
        return factoryBean.getObject();
    }

    @Bean
    public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory, ExecutorType.BATCH);
  }

When I debugging, I found out the BatchExecutor executing result is correct, updateCounts==1, as following:

But when I debugging into SqlSessionTemplate, the result is -2147482646

Use the following to get batch update counts:

List<BatchResult> batchResults = sqlSession.flushStatements();
int[] updateCounts = batchResults.get(0).getUpdateCounts();

NONONO, I know(study from debugging) we can using your solution get the batch update counts. I means the public API has inconsistent behavior. We should redesign the API
