Template Engines

When generating dynamic PDFs, you usually need to render HTML through a template engine first and then pass it to bkhtmltopdf for conversion. For Java development, FreeMarker is recommended (concise and efficient); Thymeleaf can also be used depending on your preference.

Typical workflow: the system generates HTML using a template engine → HTTP POST to the bkhtmltopdf API → output PDF.
