I enjoyed yesterday’s chat at Code Remix Weekly by Moderne. We talked about Arconia, how it enhances the developer experience for Java and Spring Boot apps, and the key role of OpenRewrite for maintaining and growing the project. https://www.youtube.com/watch?v=v_KpRj9UXls

In this new article, I describe how to build a Retrieval Augmented Generation system in Java using Spring AI and Docling for advanced, privacy-focused document processing. You'll learn how to design an Ingestion Pipeline powered by Docling for loading, converting, and chunking any type of document for your RAG use cases.

Docling is an open-source, privacy-focused solution for advanced document parsing. Using the brand-new Docling Java SDK and Arconia, I'll show you how to integrate Docling into your Spring Boot applications, and prepare documents for RAG and GenAI.

And yes, it's about time I publish better documentation for the Arconia Migrations project. That will come soon on arconia.io. In the meantime, you can check the project repository and register bugs/feature requests there. https://github.com/arconia-io/arconia-migrations Thanks 😊

The process takes care of upgrading also Spring Framework, JUnit, and Testcontainers with recipes provided by Arconia, as well as Jackson 3 and Gradle with recipes provided by OpenRewrite. More information: https://github.com/arconia-io/arconia-migrations/blob/main/docs/spring-boot.md

Spring Boot 4 looks amazing 🤩🍃 I have implemented OpenRewrite recipes to automate most of the migration process and handle the major breaking changes. You can run them with the Arconia CLI or using the OpenRewrite Gradle/Mavens plugin. Let me know what you think! I'm planning further improvements.

Spring Boot 4 is here 🚀 🍃

I have updated my OpenRewrite recipes to upgrade a Spring Boot application to the latest Spring AI 1.1 release. You can run them with the Arconia CLI or via the OpenRewrite Gradle/Maven Plugin. More details: https://github.com/arconia-io/arconia-migrations/blob/main/docs/spring-ai.md

@joschi thanks for your feedback! I wrote the blog post myself. I found challenging to explain the problem, to be honest. And that shows. I’ve been sitting on it for a few days, but I didn’t want to delay the publication fourther. Maybe I should have 😅 I’ll give it a second try to improve it, thank you!

The goal of Arconia OpenTelemetry is to provide a single dependency you can add to your Spring Boot application to get unified Java observability with minimal configuration and maximum compatibility with both OpenTelemetry and Micrometer ecosystems.

Introducing Dev Services for #SpringBoot using #Arconia by @thomasvitale

https://www.thomasvitale.com/arconia-dev-services-spring-boot/

Enhance the Spring Boot developer experience with Arconia Dev Services: zero-code and zero-config infrastructure provisioning. Add one dependency. That's it!

Databases, event queues, observability platforms, AI services and more. All powered by Testcontainers!

Java 25 comes with great features and enhancements, including making the language more succinct and beginner-friendly. This is a fully valid Java program. No imports. No method modifiers. No unneeded arguments. And you can run it directly via the "java" CLI. No extra compilation steps. #java

You can find a complete example here: https://github.com/arconia-io/arconia-examples/tree/main/arconia-openinference

In the latest release of Arconia, I included support for the OpenInference Semantic Conventions for instrumenting your Java Spring AI apps and integrating with AI platforms like Arize Phoenix, now available as an Arconia Dev Service for Spring Boot.

Arconia is a framework I've been building on top of Java and Spring Boot, focusing on developer experience and cloud native. In the latest release, I shipped a new module to integrate with Docling, an open-source, AI-powered, advanced document processor. JBang makes it really convenient to run!

I had a really great time at Spring I/O ☀️ This is the recording of my presentation about Modular RAG Architectures, where I cover several RAG patterns that you can implement in your Spring Boot application using Spring AI + Arconia (for enhanced developer experience).

Nix Flakes are great. However, they can only be distributed via Git. I think OCI would be a better distribution format, especially for enterprise use cases. Several startups are working on their own systems to improve Flake usage and distribution, but none of them seem to be considering #OCI... I hope the "Gitless GitOps" moment that we recently experienced in the cloud native ecosystem (moving from Git to OCI for configuration artefacts) will eventually materialise in Nix as well.

I had an interesting chat with @kevindubois and Olimpiu Pop on the latest episode of the @infoq Podcast. We talked about developer experience, cloud native, serverless, generative AI, and the role of #Java as a modern ecosystem to tackle all these areas, continuously evolving to adapt to new industry and developers’ needs.
