[英]Unable to write to an excel (Selenium WebDriver) - Apache POI
[英]Write data into new row in excel file whenever i run the code using Apache POI in Selenium WebDriver
我是 selenium 和 java 的新手,每當我在 Selenium WebDriver 中使用 Apache POI 運行代碼時,我都試圖將數據寫入 excel 文件中的新行。 我有以下代碼。
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import com.google.common.collect.Table.Cell;
public class ExcelWrite {
public static void main(String[] args) throws InvalidFormatException, IOException
{
File file = new File("D:\\Selenium_Training\\SeleniumFile.xlsx");
FileInputStream FIS = new FileInputStream(file);
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sh = wb.getSheetAt(0);
int x = sh.getLastRowNum();
if(x==0)
{
XSSFRow row = sh.createRow(0);
row.createCell(0).setCellValue("TC001");
row.createCell(1).setCellValue("Successfully logged in");
row.createCell(2).setCellValue("Pass");
}
else
{
int y=x++;
XSSFRow row1 = sh.createRow(y);
row1.createCell(0).setCellValue("TC001");
row1.createCell(1).setCellValue("Successfully logged in");
row1.createCell(2).setCellValue("Pass");
}
FileOutputStream fout = new FileOutputStream(file);
wb.write(fout);
fout.close();
}
}
運行代碼時出現以下錯誤,
Exception in thread "main" java.lang.IllegalArgumentException: Sheet index (0) is out of range (no sheets)
at org.apache.poi.xssf.usermodel.XSSFWorkbook.validateSheetIndex(XSSFWorkbook.java:1061)
at org.apache.poi.xssf.usermodel.XSSFWorkbook.getSheetAt(XSSFWorkbook.java:848)
at day1.ExcelWrite.main(ExcelWrite.java:28)
根據給出的幫助,我修改了如下代碼
public static void main(String[] args) throws InvalidFormatException, IOException
{
File file = new File("D:\\Selenium_Training\\SeleniumFile.xlsx");
OPCPackage pkg = OPCPackage.open(file);
XSSFWorkbook wb = new XSSFWorkbook(pkg);
XSSFSheet sh = wb.getSheetAt(0);
int x = sh.getLastRowNum();
if(x==0)
{
XSSFRow row = sh.createRow(0);
row.createCell(0).setCellValue("TC001");
row.createCell(1).setCellValue("Successfully logged in");
row.createCell(2).setCellValue("Pass");
}
else
{
int y=x++;
XSSFRow row1 = sh.createRow(y);
row1.createCell(0).setCellValue("TC001");
row1.createCell(1).setCellValue("Successfully logged in");
row1.createCell(2).setCellValue("Pass");
}
FileOutputStream fout = new FileOutputStream(file);
wb.write(fout);
fout.close();
}
但是現在我收到以下錯誤,
Exception in thread "main" org.apache.poi.POIXMLException: java.io.IOException: Can't obtain the input stream from /docProps/app.xml
at org.apache.poi.POIXMLDocument.getProperties(POIXMLDocument.java:141)

你能幫忙嗎,在此先感謝。
您的問題在於以下三行:
File file = new File("D:\\Selenium_Training\\SeleniumFile.xlsx");
FileInputStream FIS = new FileInputStream(file);
XSSFWorkbook wb = new XSSFWorkbook();
在這里,您犯了兩個錯誤。 首先,您將忽略文件,並創建一個新的空工作簿。 其次, 當您有文件時 ,您嘗試使用InputStream,文檔解釋的速度較慢並且使用了更多的內存
最好只用以下任一代碼替換該代碼:
File file = new File("D:\\Selenium_Training\\SeleniumFile.xlsx");
OPCPackage pkg = OPCPackage.open(file);
XSSFWorkbook wb = new XSSFWorkbook(pkg);
要么:
File file = new File("D:\\Selenium_Training\\SeleniumFile.xlsx");
Workbook wb = WorkbookFactory.open(file);
像現在一樣,使用常見的SS類(如Sheet
和Row
)代替特定於XSSF的類(如XSSFSheet
,這將使您的代碼可同時用於.xlsx
和.xls
文件
您可以使用下面的代碼。但不要忘記您必須手動將excel加載到項目中。 並且該 excel文件的第一個工作表應該有一個工作表名稱
public void writeDataToExcel(String email, String firstName, String lastName) throws IOException {
try {
FileInputStream file = new FileInputStream(new File(System.getProperty("user.dir") + "\\Data\\Deneme.xlsx"));
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet sheet = workbook.getSheetAt(0);
Row row = sheet.createRow(sheet.getLastRowNum() + 1);
Cell cell = row.createCell(0);
Cell cellFn = row.createCell(1);
Cell cellLn = row.createCell(2);
cell.setCellValue(email);
cellFn.setCellValue(firstName);
cellLn.setCellValue(lastName);
file.close();
FileOutputStream outFile = new FileOutputStream(new File(System.getProperty("user.dir") + "\\Data\\Deneme.xlsx"));
workbook.write(outFile);
outFile.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
