尝试{



try (FileInputStream file = new FileInputStream(new File(filename))) {

public static void setExcelFile(String Path, String SheetName) throws IOException, InvalidFormatException {
        try {

            // Open the Excel file

            FileInputStream ExcelFile = new FileInputStream(Path);

            // Access the required test data sheet

            ExcelWBook = new XSSFWorkbook("C:\\Users\\data.xlsx");
            ExcelWSheet = ExcelWBook.getSheet(SheetName);

        } catch (Exception e) {

            throw (e);

        }

    }
