Spring Tips: The GraalVM Native Image Builder Feature

speaker: Josh Long (@starbuxman)

Hi, Spring fans! Welcome to another installment of Spring Tips. In this installment, we’re going to look at the new support just released for building Spring Boot applications with GraalVM. We’ve looked at GraalVM and native images in another Spring Tips when we looked at Spring Fu.

GraalVM is several things. It’s a C1 replacement for a standard OpenJDK install. You can listen to this episode of my podcast, A Bootiful Podcast, with GraalVM contributor and Twitter engineer Chris Thalinger, for more details on this use of GraalVM. It lets you run regular Sring applications faster in certain conditions, and so it’s worth exploring for that reason alone.

Announcing the Spring Authorization Server

I am pleased to announce the Spring Authorization Server project. It is a community-driven project led by the Spring Security team and is focused on delivering Authorization Server support to the Spring community.

A Foundation for Success

The story of how we got here is long, but the key takeaway is short and sweet: Spring would not be what it is without our amazing community.

Almost a decade ago, we brought in a community-driven, open-source project, Spring Security OAuth, and made it part of the Spring portfolio of projects. Since its inception, it has evolved into a mature project that supports a large portion of the OAuth specification, including resource servers, clients, login, and the authorization server. It is no wonder that it has become the basis for UAA, which, among other things, acts as the identity management service for all Cloud Foundry installations. The Spring Security OAuth project has become a model project and is a testament to what our wonderful community can accomplish.

Spring GraalVM Native 0.6.0 released

The Spring team have just released version 0.6.0 of the spring-graalvm-native project. This project is intended to make it easier for anyone trying to build GraalVM native images of their Spring applications.

For a deep dive on native images with Spring, please see the Devoxx talk by Sébastien Deleuze.

In this blog post we’ll talk about what has changed since then and point you to some key resources enabling you to try it out! This project is in the spring-projects-experimental github org, indicating it is a work in progress, but we have a number of sample applications showing the kinds of technology that are already working and lots of documentation on how to experiment with your own apps.

Spring Tips: The Spring Integration Kotlin DSL

speaker: Josh Long (@starbuxman)

Hi, Spring fans! In this installment, we’re going to take a look at the new Kotlin DSL for Spring Integration. I’ve covered both Spring Integration and Kotlin in other videos before. I am pretty sure I’ve also used Spring Integration from within a Kotlin-based Spring application, but this is the first time I’ve been able to cover a Kotlin DSL specifically for Spring Integration.

Spring Integration has been around for a long time - 13 years at least - and it serves a timeless use case: the integration of disparate systems and services. It’s patterned after the seminal tome by Gregor Hohpe and Bobby Woolf, Enterprise Integration Patterns. It’s a fantastic tome, and I couldn’t more enthusiastically recommend it as it serves, after a fashion, as the documentation required for understanding Spring Integration. Spring Integration codifies the patterns from the book; API elements are named for the relevant patterns in the book.

Spring Data for Apache Solr Discontinued

Dear Spring Data Community,

We want to share news with you about the Spring Data for Apache Solr module.
After its initial rise as one for the first community-led Spring Data projects and its later inception as one of the core modules, community interest, feature requests, and bug reports have declined.

In our effort to balance time (based on popularity and usage data of the projects we have) the module has seen only occasional updates and fixes for the past few years. This is why we are seeking volunteers who are willing to help maintain the module, putting Spring Data for Apache Solr back into community mode.

Getting Started With RSocket: Spring Boot Channels

Reading Time: about 6 minutes.
Practice Time: about 20 minutes.

If, like me, you’re still at the beginning of your RSocket journey, check out the motivations behind the RSocket protocol. This short but insightful document includes one message that resonates very strongly with me — ‘a mismatched abstraction increases the cost of developing a system.’

From a software design point of view, RSocket’s four interaction models offer a significant benefit. It means we can model our component-to-component communications using the correct interaction model for each use case. This more productive model could save you lots of time and energy when coding!
