Arconia Docling (Spring Boot + Dev Service)

README.md

Arconia Docling

This is a minimal application demonstrating the use of Arconia Docling which provides a seamless Spring Boot integration with Docling, a powerful AI-powered document conversion service that transforms documents into structured formats like Markdown.

Run the application with JBang:

jbang Application.java

Under the hood, the Arconia framework will automatically spin up a Docling server using Testcontainers (see Arconia Dev Services for more information).
