OpenAI provides specialized models for speech-to-text and text-to-speech conversion, recognized for their performance and cost-efficiency. Spring AI integrates these capabilities via Voice-to-Text and Text-to-Speech (TTS).

The new Audio Generation feature (gpt-4o-audio-preview) goes further, enabling mixed input and output modalities. Audio inputs can contain richer data than text alone. Audio can convey nuanced information like tone and inflection, and together with the audio outputs it enables asynchronous speech-to-speech interactions. Additionally, this new multimodality opens up possibilities for innovative applications, such as structured data extraction. Developers can extract structured information not just from simple text, but also from images and audio, building complex, structured objects…

Since its inception, Spring Data Repositories have been designed for extension, whether you want to customize a single query method or provide a completely new base implementation.

The 2024.1 release enhances your ability to extend a repository with custom functionality making it easier than ever for anyone to create extensions that can be shared across different projects.

Let’s explore an example to see how this works in practice.

Imagine you are using MongoDB as a document store to manage a movie database. You want to leverage MongoDBs Atlas vector search functionality through your…

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's the first week of December and I am in the amazing city of Perth, Australia. Perth, for those of you who don't know, is amazing. And well worth the journey. But it is quite the journey! 27 hours, door-to-door, from San Francisco to Perth! Insanity.

I'm super happy to be here, though, talking to amazing folks before I begin my journey from Melbourne, Brisbane, and Sydney, Australia for the epic YOW! conference. It's going to be a ton of fun.

• I love this InfoQ interview with Spring Framework lead Jürgen Hoeller and Spring Framework contributor Sébastien Deleuze
• I also love this article on reactive websockets with Spring
• Extending Spring Data repositories just got easier!
• Huh. Apparently the old SpringSource repositories just got sunsetted. I had no idea we still maintained them.
• In this week's installment of A Bootiful Podcast, I talk to Dave Cramer, PostgreSQL and PostgreSQL JDBC driver contributor extraordinairre
• Spring Cloud 2023.0.4 is now available
• Spring Cloud Stream Applications is now available
• HTTP3 in Reactor!

Hi, Spring fans! Happy Thanksgiving to my American listeners! and happy Thursday to the everyone! In today's episode I talk to PostgreSQL and PostgreSQL JDBC contributor Dave Cramer. #postgresql #jdbc #sql #java

HTTP/3, the latest major version of the Hypertext Transfer Protocol, had its specification finalized in June 2022. This version is designed to enhance performance, reliability, and security. Unlike its predecessors, HTTP/3 utilizes QUIC instead of TCP as its transport layer. QUIC is a UDP-based, multiplexed, and secure transport protocol that includes built-in TLS 1.3 encryption, making QUIC encrypted by default.

To learn more about the performance and benefits of HTTP/3, check out What is HTTP/3.

For information on browser adoption, take a look at Examining HTTP/3 Usage, which also provides raw data on HTTP versions used by…

This Week in Spring - November 26th, 2024

Hi, Spring fans! Welcome to another installment of This Week in Spring!

Happy Spring Boot 3.4 release month to those who celebrate! And, also, Happy Thanksgiving to those who celebrate! Spring Boot 3.4 brings with it long-anticipated updates to the entire portfolio of Spring projects, and so a lot of the content in this roundup has to do with those releases!

• Starting with an interview with Spring Framework lead Juergen Hoeller and Spring Framework contributor Sébastien Deleuze over on InfoQ
• Reactor legend Violeta Georgieva has a nice post introducing HTTP/3 support in Reactor 2024.0
• I have thoughts on all the amazing new opportunities in Spring Boot 3.4! Like, 50 pages or so worth. So I wrote them all down and published them as a series of blogs looking at Spring Framework, Spring Data, Spring Batch, Spring Integration, Spring Security, Spring Modulith, and Spring AI. Here's the starting blog post, which serves as a sort of index for all the other posts.
  • And here's the post on Spring Framework
  • And here's the post on Spring Data
  • And here's the post on Spring Batch
  • And here's the post on Spring Integration

Hi, Spring fans! And happy Spring Boot 3.4 release to those who celebrate!

I know, I know what you're thinking: Josh, Spring Boot 3.4 already shipped! I know it. Spring Boot 3.4 dropped a week earlier this year! In the last couple of years, we’ve released Spring Boot on the same day as Thanksgiving Day in the USA, which is tedious for us here in the United States because it requires more preparation. This year, it’s a week early! Why do I mention this? Well, I’ve had some time already - before Thanksgiving, even - to explore the fantastic possibilities unlocked by using Spring Boot 3.4. While…

I love Spring AI. It’s an amazing project designed to bring the patterns and practices of AI engineering to the Spring Boot developer. It’s got clean idiomatic abstractions that’ll make any Sring developer feel right at home, and it has a ton of integrations with all manner of different vector stores, embedding models, transcription models, image modes, and chat models.

The new release, m4, builds upon Spring Boot 3.4 and adds a ton of new features. As usual, I can’t hope to look at all the new features, but the release notes do an exquisite job.

• there’s new Amazon Bedrock Convertse support
• there’s been a ton of work done to support more expressive function calling, both in Java and Kotlin
• there’s the first cut of support for the ideas taking shape in the AI community around "advanced and modular RAG". RAG, of course, is retrieval augmented generation and refers to using data from a system or service to inform the response generated by a chat model. These ideas are articulated in this paepr and this one, and the building blocks are taking root in this new release. Amazing!
