java - 当在文本框中输入一定数量时生成条形码，

Question

当在文本框中输入一定数量时，我需要生成条形码。但似乎可以使用我制作的代码。任何帮助将不胜感激。

import com.aspose.barcode.BarCodeBuilder;
import com.aspose.barcode.Symbology;
import com.aspose.words.Document;
import com.aspose.words.DocumentBuilder; 

   JButton btnCreate = new JButton("Create Barcode");
            btnCreate.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent arg0) {
                    String strBaseFolder = "C:\\users\\ronjonathan\\desktop\\barcode\\";
                    try

                    {

                        // Generate barcode image
                        BarCodeBuilder builder = new BarCodeBuilder();
                        builder.setSymbologyType(Symbology.Code128);
                        for(int i = 1;i <= Integer.parseInt(txtBarcode.getText()); i++){

                        builder.setCodeText(Integer.toString(i));
                        String strBarCodeImageSave = "img.jpg"+ i;
                        builder.save(strBaseFolder + strBarCodeImageSave);

每次运行此代码时，您都会覆盖同一个文件“img.jpg”。尝试改变

String strBarCodeImageSave = "img.jpg";

到

String strBarCodeImageSave = txtBarcode.getText() + ".jpg";
