Generate barcode and QR code using itext

The code for generating barcode mainly comes from the sample code provided on the itext official website. However, when using the Chinese tag, the Chinese part is blank.

When using Chinese in itext, you first need to download the itext-asian.jar file and add it to the project class path.

For more information, see the code.
