案例：我的字符串位置是动态的，所以我必须在Excel中搜索字符串位置，然后获取该位置旁边的值。
这是我尝试过的：
public class AssetRegisterDepreciationReport {
    public static void ReadAssetExcelData() throws IOException {
        String cellContent = "Grand Total:";
        int rownr, colnr = 5;
        FileInputStream assetReport = new FileInputStream("C:\\Users\\Admin\\Downloads\\Asset_Depreciation_14_03_2020 19-05-31.xlsx");
        @SuppressWarnings("resource")
        XSSFWorkbook assetWorkbook = new XSSFWorkbook(assetReport);
        XSSFSheet sheetNumber1 = assetWorkbook.getSheetAt(0);
        rownr = findRow(sheetNumber1, cellContent);
        output(sheetNumber1, rownr, colnr);
        finish();
    }
    private static void output(XSSFSheet sheetNumber1, int rownr, int colnr) {
        XSSFRow row = sheetNumber1.getRow(rownr);
        XSSFCell cell = row.getCell(colnr);
        System.out.println("您的总数是：" + cell);
    }
    private static int findRow(XSSFSheet sheetNumber1, String cellContent) {
        int rowNum = 0;
        for (Row row : sheetNumber1) {
            for (Cell cell : row) {
                switch (cell.getCellType()) {
                    case STRING:
                        if (cell.getRichStringCellValue().getString().equals(cellContent)) {
                            rowNum = row.getRowNum();
                            System.out.println(rowNum);
                        }
                        break;
                    default:
                        break;
                }
            }
        }
        return rowNum;
    }
    private static void finish() {
        System.exit(0);
    }
}

if(cell.getRichStringCellValue().getString().equals(cellContent))
