mybatis 使用sqlSessionFactory實現批量操作

sqlSessionFactory實現批量提交的java,但無法返回受影響數量。

public int updateBatch(List<Object> list){
        if(list ==null || list.size() <= 0){
            return -1;
        }
        SqlSessionFactory sqlSessionFactory = SpringContextUtil.getBean("sqlSessionFactory");
        SqlSession sqlSession = null;
        try {
            sqlSession = sqlSessionFactory.openSession(ExecutorType.BATCH,false);
            Mapper mapper = sqlSession.getMapper(Mapper.class);
            int batchCount = 1000;//提交數量,到達這個數量就提交
            for (int index = 0; index < list.size(); index++) {
                Object obj = list.get(index);
                mapper.updateInfo(obj);
                if(index != 0 && index%batchCount == 0){
                    sqlSession.commit();
                }                    
            }
            sqlSession.commit();
            return 0;
        }catch (Exception e){
            sqlSession.rollback();
            return -2;
        }finally {
            if(sqlSession != null){
                sqlSession.close();
            }
        }
        
}

@Component
public class SpringContextUtil implements ApplicationContextAware{

    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringContextUtil.applicationContext = applicationContext;
    }

    public static ApplicationContext getApplicationContext(){
        return applicationContext;
    }

    public static Object getBean(Class T){
        try {
            return applicationContext.getBean(T);
        }catch (BeansException e){
            return null;
        }
    }

    public static Object getBean(String name){
        try {
            return applicationContext.getBean(name);
        }catch (BeansException e){
            return null;
        }
    }
