itextpdf Chinese font problem

You can use the getResourstream method to retrieve the input stream of the font file. This is then converted to a byte array, and the BaseFont.createFont method is used to create a custom font. Here is a sample code:

String fontPath = "/static/font/simsun.ttc";
InputStream fontStream = this.getClass().getResourceAsStream(fontPath);
if (fontStream == null) {
    throw new FileNotFoundException("Font file not found: " + fontPath);
}
byte[] fontData = IOUtils.toByteArray(fontStream);
BaseFont customFont = BaseFont.createFont("simsun", BaseFont.IDENTITY_H, BaseFont.EMBEDDED, false, fontData, null);
Font font = new Font(customFont, 12, Font.NORMAL);

This example assumes that the font files are in the /static/font/simsun.ttc path of the classpath. If your font files are on a different path, you can change the value of the fontPath variable accordingly.

In iText PDF, you can use the FontFactory class to load custom fonts. To avoid absolute paths, you can use relative paths to specify the location of the font file.

Assuming the font library file name is simsun.ttc in the resources/static/font/ directory of your project, you can load it as follows:

1. introduces the FontFactory class into the code:

import com.itextpdf.text.FontFactory;

1. Sets the path to the font library file:

String fontPath = "resources/static/font/simsun.ttc";

1. Loading font:

FontFactory.register(fontPath, "simsun");

This allows you to register the font library file with iText and give it a name of "simsun". You can then refer to the font by that name in your code.
