You are trying to read xls with explicit implementation poi classes for xlsx.

G：\\硒Jar文件\\ TESTDATA \\数据 XLS

G:\Selenium Jar Files\TestData\Data.xls

要么使用HSSFWorkbook$c$c>和HSSFSheet$c$c>类或让您的实现更通用，通过使用共享接口等;

Either use HSSFWorkbook and HSSFSheet classes or make your implementation more generic by using shared interfaces, like;

修改

XSSFWorkbook workbook = new XSSFWorkbook(file);

要：

 org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(file);

和变化：

XSSFSheet sheet = workbook.getSheetAt(0);

要：

org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);
