Question

在我的程序中，我想在excel表中找到与我作为参数传递的字符串匹配的行号。它适用于第一行和第二行但问题是下一行。我找到行号的代码如下：

    public int findrownum(String sName, String value, int cNum) throws Exception{
        File excel = new File(filepath);
        FileInputStream fis = new FileInputStream(excel);
        XSSFWorkbook wb = new XSSFWorkbook(fis);
        XSSFSheet ws = wb.getSheet(sName);
        boolean check = true;
        int i=0;
        while (check){
            XSSFRow rowH = ws.getRow(i);
            XSSFCell cell = rowH.getCell(cNum);
            String cellvalue = cellToString(cell);
            if (cellvalue.equals(value)){
                check = false;
            }
            else {
                i = i+1;
            }
        }       

        return i;
    }

}

我想从excel

中读取第三行，即具有名称注册的字符串

请告诉我代码中需要进行哪些更改。

由于

我在JUNIT中使用了@eric提到的类似逻辑，现在我能够找到行号。但是当我尝试使用此行号读取数据时，它给出了错误。我的数据读取代码如下。请告诉我需要做什么更改public String dataread（String sName，int rNum，String cName）throws Exception { 文件excel =新文件（文件路径）; FileInputStream fis = new FileInputStream（excel）; XSSFWorkbook wb = new XSSFWorkbook（fis）; XSSFSheet ws = wb.getSheet（sName）; XSSFRow rowH = ws.getRow（rNum-1）; int totalRows = ws.getLastRowNum（）;

    int i =0;
    for(i=0;i<=totalRows;i++)

    {
        XSSFCell cell = rowH.getCell(i);
        String value = cellToString(cell);
        if (value.equals(cName)){
             System.out.println(i);
             break;
        }

    }
    XSSFRow row = ws.getRow(rNum);
    XSSFCell cell = row.getCell(i);
    String value = cellToString(cell)          return value;
}

Answer 1

通常From this Documentation你可以使用getHeight（）获取光标，而不是编写自己的循环。显然这也会减少执行时间。此外，您编写的代码可能导致异常，因为没有更多的物理行。

ws.getRow(i); can cause a fatal error if i>height of the last row

希望以下代码有所帮助。假设单元格中的数据是字符串数据。这也是apache poi api。

public static String getcellValue(int testRowNo, int colNo)
    {
        String projectPath = System.getProperty("user.dir");
        String excelPath = projectPath + "/TestSet.xlsx";
        File excel = new File(excelPath);
        FileInputStream fis = null;
        Workbook workBook = null;
        String cellValue = null;
        try
        {
            fis = new FileInputStream(excel);
            workBook = WorkbookFactory.create(fis);
            Sheet workSheet = workBook.getSheet(sheetName);
            int totalRows = workSheet.getLastRowNum();
            Row row = null;
            cellValue  = workSheet.getRow(testRowNo).getCell(colNo).getStringCellValue();


        } catch (InvalidFormatException e)
        {
            e.printStackTrace();
        } catch (IOException e)
        {
            e.printStackTrace();
        }finally
        {
            try
            {
                fis.close();
            } catch (IOException e)
            {
                e.printStackTrace();
            }
        }
        return cellValue;
    }

public static int getrowNumber(String sheetName, String cellData)
    {
        String projectPath = System.getProperty("user.dir");
        String excelPath = projectPath + "/TestSet.xlsx";
        File excel = new File(excelPath);
        FileInputStream fis = null;
        Workbook workBook = null;
        String cellValue = null;
        try
        {
            fis = new FileInputStream(excel);
            workBook = WorkbookFactory.create(fis);
            Sheet workSheet = workBook.getSheet(sheetName);
            int totalRows = workSheet.getLastRowNum();
            Row row = null;
            int testRowNo = 0;
            for(int rowNo =1; rowNo<=totalRows; rowNo++)
            {
                row = workSheet.getRow(rowNo);
                testRowNo = testRowNo +1;
                if(row.getCell(0).getStringCellValue().equalsIgnoreCase(cellData))
                {
                    break;
                }
            }


        } catch (InvalidFormatException e)
        {
            e.printStackTrace();
        } catch (IOException e)
        {
            e.printStackTrace();
        }finally
        {
            try
            {
                fis.close();
            } catch (IOException e)
            {
                e.printStackTrace();
            }
        }
        return testRowNo;
    }
