推荐答案

iText 是一个很棒的Java PDF库。他们还有一个用于创建条形码的API。您无需创建PDF即可使用它。

iText is a great Java PDF library. They also have an API for creating barcodes. You don't need to be creating a PDF to use it.

此页面包含创建条形码。以下是该网站的示例：

This page has the details on creating barcodes. Here is an example from that site:

BarcodeEAN codeEAN = new BarcodeEAN();
codeEAN.setCodeType(codeEAN.EAN13);
codeEAN.setCode("9780201615883");
Image imageEAN = codeEAN.createImageWithBarcode(cb, null, null);

您需要确定的最重要的事情是您需要什么类型的条形码。有许多不同的条形码格式，iText确实支持很多。在确定此API是否适合您之前，您需要知道所需的格式。

The biggest thing you will need to determine is what type of barcode you need. There are many different barcode formats and iText does support a lot of them. You will need to know what format you need before you can determine if this API will work for you.
