Question

我正在学习selenium webdriver并尝试使用下面的代码段使用Apache POI lib来阅读excel。它已成功运行但在更新excel文件后。它不会读取更新的值或Excel数据。始终打印以前的内容。

public org.apache.poi.ss.usermodel.Sheet sheet;

public static FileInputStream ReadExcel;

public void read_excel(String excel_file_path, String DataSheetName) throws Exception, IOException

{
    try
    {

    ReadExcel=new FileInputStream(new File(excel_file_path));

        Workbook wp=WorkbookFactory.create(ReadExcel);
        sheet=wp.getSheet(DataSheetName);
        Iterator<Row> rowIterator=sheet.rowIterator();

        while(rowIterator.hasNext())
        {

            Row row=rowIterator.next();
            Iterator<Cell> cellIterator=row.cellIterator();

            while(cellIterator.hasNext())
            {
                Cell cell=cellIterator.next();
                String cellData=cell.getStringCellValue();
                System.out.println(cellData);
            }

        }
        ReadExcel.close();

    }

    catch(Exception e)
    {
        e.printStackTrace();

    }

excel表格中有哪些更新？尝试使用以前版本的文件格式与excel 97-2003工作簿另一个解决方案是excel文件的路径尚未被修改，因此它不使用较新的文件。同时检查文件名，因为您在此处将其用作字符串。

下面是Excel文件读取示例TC：

package excelExportAndFileIO;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;

import org.apache.poi.ss.usermodel.Row;

import org.apache.poi.ss.usermodel.Sheet;

import org.apache.poi.ss.usermodel.Workbook;

import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class aafileread {



    public void readExcel(String filePath,String fileName,String sheetName) throws IOException{

    //Create a object of File class to open xlsx file

    File file =    new File(filePath+"\\"+fileName);

    //Create an object of FileInputStream class to read excel file

    FileInputStream inputStream = new FileInputStream(file);

    Workbook FILENAME = null;


    String fileExtensionName = fileName.substring(fileName.indexOf("."));

    //Check condition if the file is xlsx file

    if(fileExtensionName.equals(".xlsx")){

    //If it is xlsx file then create object of XSSFWorkbook class

    filename = new XSSFWorkbook(inputStream);

    }

    //Check condition if the file is xls file

    else if(fileExtensionName.equals(".xls")){

        //If it is xls file then create object of XSSFWorkbook class

        Filename = new HSSFWorkbook(inputStream);

    }

    //Read sheet inside the workbook by its name

    Sheet Sheetname = Filename.getSheet(sheetName);

    //Find number of rows in excel file

    int rowCount = sheetname.getLastRowNum()-sheetname.getFirstRowNum();

    //Create a loop over all the rows of excel file to read it

    for (int i = 0; i < rowCount+1; i++) {

        Row row = sheetname.getRow(i);

        //Create a loop to print cell values in a row

        for (int j = 0; j < row.getLastCellNum(); j++) {

            //Print excel data in console

            System.out.print(row.getCell(j).getStringCellValue()+"|| ");

        }

        System.out.println();

    }



    }



    //Main function is calling readExcel function to read data from excel file

    public static void main(String...strings) throws IOException{

    //Create a class

    FilenameFile objExcelFile = new FilenameFile();

    //Prepare the path of excel file

    String filePath = System.getProperty("user.dir")+"\\src\\excelExportAndFileIO";

    //Call read file method of the class to read data

    objExcelFile.readExcel(filePath,"Filename.xlsx","Filename");

    }

}

更新后无法读取excel
