如何删除 POI 生成的 Excel 中的警告？

I am using Apache POI for writing content into excel sheet. after generating an excel in all the cells which ever cell has numbers, it contains one blue mark(each cells left top corner). its like a warning. how can i remove them while writing the content to excel? PFA screen shot.

Thanks!

您可以尝试设置单元格类型：

HSSFCell cell = row1.createCell(i);
cell.setCellType(Cell.CELL_TYPE_STRING); // =0, or Cell.CELL_TYPE_NUMERIC = 1
cell.setCellValue(value);

See the API docs http://poi.apache.org/apidocs/org/apache/poi/hssf/usermodel/HSSFCell.html#setCellType%28int%29了解更多信息。
