java对Excel表格数据处理并以List集合返回（只要传Excel文件路径即可）

public static List<List<String>> readXlsx(String path) throws Exception {        InputStream is = new FileInputStream(path);        XSSFWorkbook xssfWorkbook = new XSSFWorkbook(is);        List<List<String>> result = new ArrayList<List<String>>();        // 循环当前页，并处理当前循环页        XSSFSheet xssfSheet = xssfWorkbook.getSheetAt(0);        // 循环每一页，并处理当前循环页//        for (XSSFSheet xssfSheet : xssfWorkbook) {//            String a = xssfSheet.getSheetName();//            if (xssfSheet.gets(0) != "月度汇总") {//                continue;//            }        // 处理当前页，循环读取每一行 rowNum:从第几行开始读取        for (int rowNum = 3; rowNum <= xssfSheet.getLastRowNum(); rowNum++) {            XSSFRow xssfRow = xssfSheet.getRow(rowNum);            int minColIx = xssfRow.getFirstCellNum();            int maxColIx = xssfRow.getLastCellNum();            List<String> rowList = new ArrayList<String>();            for (int colIx = minColIx; colIx < maxColIx; colIx++) {                XSSFCell cell = xssfRow.getCell(colIx);                if (cell == null) {                    continue;                }                rowList.add(cell.toString());            }            result.add(rowList);        }//        }        return result;
