Spring Tips: Spring and GraalVM (pt. 2)

speaker: Josh Long (@starbuxman)

Hi Spring fans! Welcome to a very special, interregnum episode of Spring Tips where we revisit Spring and GraalVM native images. I wanted to get this video out in light of the recent Spring Graal 0.7.1 release which drastically simplifies things even compared to the last time we looked at Spring and Graal waaay back in April 2020.

TL;DR: GraalVm is a JIT replacement that you can use with a stock-standard JVM, and that's worth looking into in its own right. GraalVM also offers a separate feature supporting native image compilation. This native-image builder takes bytecode and turns it into an architecture-specific binary that sheds the JVM and embeds something called SubstrateVM. Native images are fast to startup and they take way

This Week in Spring - June 16th, 2020

Engineering | Josh Long | June 16, 2020 | ...

Hi, Spring fans! Welcome to another jam-packed weekly roundup of This Week in Spring.

I've got a few upcoming speaking engagements you might be interested in. I'll be speaking (virtually) at the San Francisco JUG on June 24th at 6:30 PM. Join me!

Can't make it to the (virtual) SF JUG appearance? On June 30th, VMware Tanzu (where the Spring team lives) will be hosting one of my workshops, also on Reactive Spring. I'm going to cover tons of stuff: R2DBC, Reactor, Spring WebFlux, Spring WebFn, reactive Spring Data for SQL and NoSQL, RSocket, reactive security, reactive service orchestration, and composition patterns, and more. This is going to be at an ideal time for EU timezones, so please register now

Spring Cloud Data Flow 2.6.0-M1 Released

Spring Cloud Data Flow team is pleased to announce the first milestone release of 2.6.0.

This 2.6.0-M1 adds some bug fixes and the following features:

  • Composed Task Runner as SCDF native module Composed Task Runner is now an integral part of SCDF itself and gets registered implicitly while the users who have the custom composed task runner can still override the native one. This enables us to integrate the composed tasks management within the context of Spring Cloud Data Flow. This change also allowed us to provide some additional user experiences when managing composed tasks. .

  • Improvements in task applications management This milestone added some improvements at the backend such as the ability to uniquely identify the task elements inside the composed task, adding task manifest as part of the last ran task definition, ability to cleanup task related resources as part of task definition cleanup along with the SCDF dashboard changes.

The path towards Spring Boot native applications

Engineering | Sébastien Deleuze | June 10, 2020 | ...

I would like to use the opportunity of our Spring GraalVM Native 0.7.0 release to give you a status update about our work on Spring Boot native images.


Native image provides a way to build and run Spring Boot applications with different characteristics than a regular JVM deployment:

  • The output is a native executable that contains your application with a subset of the JDK and the dependencies required to run it.

  • In practice the executable would likely be shipped in an highly optimized container image (FROM scratch Docker image is supported) with reduced surface attack which is good fit with Kubernetes.

  • Startup time is almost instant and peak performance is available immediately, allowing support for scale-to-zero (serverless) applications including for regular Spring Boot web applications.

  • Memory consumption is reduced, which is a good fit for systems split into multiple microservices.

Migrating Spring Boot's Build to Gradle

Engineering | Andy Wilkinson | June 08, 2020 | ...

We made a fairly significant change to Spring Boot in 2.3.0.M1. It was the first release of the project to be built with Gradle rather than Maven. A thread on Twitter about the migration had a number of people asking why we switched and the benefits, if any, that we’d seen. This blog post aims to answer those questions.

Each project in the Spring portfolio is run in a fairly autonomous manner. We strive for consistency where our users will see it most – API design, for example – but choose the tools that best meet the needs of the project for things that are less visible. One example of this…
