mybatis如何对大量数据的游标查询

@Mapper
public interface NewsRepository {
 
    String simpleQuery="select news.id,news.title,news.keywords," +
            "    news.url,news.author," +
            "    data.content,news.inputtime,news.updatetime " +
            " from news news join news_data data on news.id=data.id";
 
    /**
     * 使用游标查询数据数据
     * @return
     */
  
    @Select(value = simpleQuery +
            " where status=1" +
            " order by news.id asc")
    @Options(fetchSize = Integer.MIN_VALUE)//mysql情况比较特殊，只能这样设置
    Cursor<News> scrollResult();
 
}

Cursor<News> cursor= repository.scrollResult();
Iterator<News> iter= cursor.iterator();
int count=0;
while (iter.hasNext()){
     System.err.println(iter.next().title);
     ..........
}

  @Select(" SELECT * FROM temp_student ")
   Cursor<TempStudent> findListForCursor();

    @Transactional
    public void scanTempStudent() {
        Cursor<TempStudent> cursor = tempStudentDao.findListForCursor();
        
        cursor.forEach(foo -> {
            System.out.println(foo.getId() + ":" + foo.getName());
        });
    }
