在Excel中编辑文本

Question

我想在Excel文件中添加文字。我可以添加一次。但是，当我第二次尝试时，只更新最后一个值。我尝试了其他一些东西，但我没有得到答案。

while (true) {
            try {

                 clientSocket = serverSocket.accept();   //accept the client connection
                inputStreamReader = new InputStreamReader(clientSocket.getInputStream());
                bufferedReader = new BufferedReader(inputStreamReader); //get the client message
                message = bufferedReader.readLine();

                System.out.println("Java Server1 " +  message);
writeInExcel(message);

}

 public static void writeInExcel(String stock_list) throws WriteException, IOException, BiffException
    {


       Workbook existingWorkbook = Workbook.getWorkbook(new File("try.xls"));
        WritableWorkbook workbookCopy = Workbook.createWorkbook(new File("output.xls"), existingWorkbook);
        WritableSheet sheetToEdit = workbookCopy.getSheet(0);

         Label l = new Label(0, i, String.valueOf( i));
         sheetToEdit.addCell(l);

        workbookCopy.write();
        workbookCopy.close();
        existingWorkbook.close();
    }

在这里，只要我在输入流上获得某些内容，我就需要将它添加到excel文件中。 如果有人可以帮助我或者可以解释一下代码，那就太好了。在可写单元格之后，我无法完全理解代码

由于在您的代码中，您已将以下内容放在for循环中，请将其置于循环外

workbookCopy.write();
workbookCopy.close();
existingWorkbook.close();

试试这个

    Workbook existingWorkbook = Workbook.getWorkbook(new File("try.xls"));
    WritableWorkbook workbookCopy = Workbook.createWorkbook(new File("output.xls"), existingWorkbook);
    WritableSheet sheetToEdit = workbookCopy.getSheet(0);
    for(int i=0;i<5;i++)  
    {
     Label l = new Label(0, i, String.valueOf( i));
     sheetToEdit.addCell(l);
     }
    workbookCopy.write();
    workbookCopy.close();
    existingWorkbook.close();

<强> output.xls 当我把limit = 5
