Question

尝试使用工作簿wb = WorkbookFactory.create（new File（fileName））; //阅读以下链接中的xls文件

尝试了其他一些库jxcel，没有运气，如果做错了事，有人可以帮忙

XLS文件：https://www.huduser.gov/portal/datasets/excel/wy_foreclosure.zip

代码：

import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;
.......
......

try (InputStream is = new FileInputStream(new File(fileName));
                Workbook wb = WorkbookFactory.create(new File(fileName));) {

        }

异常跟踪：

要打开现有的XLS文件，您可以例如使用此代码：

import java.io.FileInputStream;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class OpenXLS {

  public static void main(String[] args) throws Exception {

    HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream("yourFile.xls"));
    // Do something with it.
    workbook.close();
  }
}

这不适用于您提供的文件。但是，当您在LO Calc中打开这些文件之一并将其保存而不进行任何更改时，一切都很好。因此，您的文件似乎不正确。
