This Week in Spring - November 5th, 2024

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's the 5th of November, 2024, and, um, I - an American - am desperately trying to keep calm and carry on. I did everything I can do (VOTE!), and so it's with considerable enthusiasm that I dive into this week's (hopefully distracting) roundup!

• Dr. David Syer announcing the Spring GRPC project
• a Spring Boot and GraalVM native image application, demonstrated by awesome Oracle GraalVM developer advocate Alina Yurenko
• understanding the Spring Boot @SpringBootApplication annotation
• understanding the lifecycle of a Spring Boot application
• there's never been a better time to be a Java and Spring developer!
• A New Developer's Journey, in 2024
• Super cool! Java 24 is targeting a fix to allow developers to synchronize code on virtual threads and avoid pinning

Hi, Spring fans! How're things? It's almost Halloween! I'm so excited! I'm going as a PHP program. Boooooooo...t. I'm writing this from the amazing Vaadin Create conference in Frankfurt, Germany, about to do my keynote for an amazing, Spring-loving audience here. So, without further ado, let's dive right into it!

• RestClient support for OAuth 2 in Spring Security 6.4
• Spring Modulith 1.3 RC1, 1.2.5, and 1.1.10 released. The RC has several cool new contributions, including one from my friend and teammate Cora Iberkleid introducing an archiving event publication completionm mode; and one contribution from me, that supports externalizing events with Spring Integration MessageChannels. Nice! Get the bits now!
• An awesome blog from Marcin Grzejszczak: Let's Use OpenTelemetry with Spring
• Spring Boot 3.4.0 RC1 is available now
• in last week's A Bootiful Podcast, I talked to GraalVM benevolent dictator …

In Spring Security 6.2 and 6.3, we have worked to steadily improve configuration for applications using OAuth2 Client. Configuration for common use cases has been simplified by allowing applications to publish beans which are automatically included in the overall OAuth2 Client configuration during application startup. Recent improvements include:

• Extension grant types can be enabled simply by publishing a bean of type OAuth2AuthorizedClientProvider (or ReactiveOAuth2AuthorizedClientProvider)
• OAuth 2.0 Access Token Requests can be extended with custom parameters simply by publishing one or more beans of type OAuth2AccessTokenResponseClient (or ReactiveOAuth2AccessTokenResponseClient)
• Spring Security automatically publishes a bean of type OAuth2AuthorizedClientManager (or ReactiveOAuth2AuthorizedClientManager) if one is not already published, requiring less boilerplate configuration when an application needs to obtain access tokens

Introduction

In the dynamic realm of observability, OpenTelemetry is a new set of tools that emerged from the now-deprecated OpenCensus and OpenTracing projects. When it comes to Spring Framework, Spring Boot, Spring Data, and Spring Cloud observability, mature solutions like Micrometer, the de facto Java standard of observability, are being used to instrument their various modules. The OpenTelemetry project consists of many components. The one we find most compelling is the OpenTelemetry Protocol (OTLP), which allows developers to harness the power of a consistent telemetry format for any…

Hi, Spring fans! In this installment I talk to GraalVM founder and benevolent dictator for life Thomas Wuerthinger, recorded live from Devoxx Belgium 2024!

Ollama now supports all GGUF models from Hugging Face, allowing access to over 45,000 community-created models through Spring AI's Ollama integration, runnable locally.

We'll explore using this new feature with Spring AI. The Spring AI Ollama integration can automatically pull unavailable models for both chat completion and embedding models. This is useful when switching models or deploying to new environments.

Setting Up Spring AI with Ollama

Install Ollama on your system: https://ollama.com/download.

Tip: Spring AI also supports running Ollama via Testcontainers or integrating with an external Ollama service via Kubernetes Service Bindings…

Hi, Spring fans! Welcome to another installment of This Week in Spring. I write this to you in an Uber speeding down the autobahn near Frankfurt, Germany. What a time to be alive!
