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 …

On behalf of the community, I am delighted to announce the avability of Spring Modulith 1.3 RC1, 1.2.5, and 1.1.10. While the service releases contain a few bugfixes and the usual dependency updates, the release candidate is packed with features and improvements such as (full change log here):

• An archiving event publication completion mode (thanks to Cora Iberkleid for the contribution).
• Support for MariaDB (thanks, @Fezlight) and Oracle DB (thanks to @DSXVII) in the JDBC-based event publication registry.
• Support to externalize events into a Spring (Integration) MessageChannel via the new spring-modulith-events-messaging artifact (thanks to Josh Long for the contribution).
• Event externalization now allows to add headers to the messages sent out and uses the Spring Message abstraction for broker interaction where feasible.
• Support for SpEL expressions in @Externalized.
• Deprecate event externalization for Amazon SQS and SNS in favor of the implementation in Spring Cloud AWS (thanks to Marcin Slowiak…

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…
