A critical piece of infrastructure, the Spring Artifactory instance repo.spring.io, lies at the heart of the Spring portfolio development work. Since 2013, JFrog, Inc. has generously sponsored the instance for the Spring developer community.

The Artifactory repository streamlines our project development by acting as a single location where Spring engineers can point their builds and by providing the community with early access to our snapshots and milestones.

Today, we are providing notice of some upcoming changes to the repository.

Upcoming Changes

If you use repo.spring.io as directed by start.spring.io, (for example, using only /snapshot and /milestone…

The following CVE reports were published today:

• CVE-2020-5403 affecting Reactor Netty HttpServer 0.9.3 and 0.9.4.
• CVE-2020-5404 affecting Reactor Netty HttpClient for all 0.8.x and 0.9.x versions in applications where the automatic following of redirects is explicitly enabled.

The fixes are in Reactor Netty 0.9.5 and 0.8.16. If using the reactor-bom, you can upgrade to Dysprosium-SR5 or Californium-SR16.

Reactor Netty is used internally in many frameworks including Spring WebFlux and its WebClient. If you have a Spring Boot application, you can upgrade to Spring Boot 2.2.5 or 2.1.13.

Spring is constantly evolving and always innovating while being consistent where it matters: delivering a reliable framework to help you build maintainable software, faster. In the last few years, the Spring contributors have worked hard to bring the predictable Spring experience to microservices, serverless, streams, reactive, batch, data, and new languages like Kotlin. Over the coming year, you'll see many more examples of this, including some cool new features that we're just dying to share with you.

However, there was one area of Spring that we felt was desperately in need of some love and…

See the latest announcement on Announcing the Spring Authorization Server. This post is a follow-up to Next Generation OAuth 2.0 Support with Spring Security

Current State

In the Spring Security 5.x release train, we’ve endeavored to replace and simplify the feature set found in the Spring Security OAuth 2.x legacy project. In the process, we’ve also added numerous new features, including support for OpenID Connect 1.0.

We are pleased to announce that as of the 5.2 release, we are very close to feature parity with the client and resource server legacy support. What remains is quite…

Speaker: Mark Heckler, Pivotal

In today’s microservices-based world, many mission-critical systems have distributed elements or are entirely distributed. Ideally, these architectures should improve things such as performance, scalability, reliability, and resilience—but subpar design can limit those strengths, or worse yet, turn them into challenges that need to be overcome.

Messaging platforms help solve these problems and improve the "ilities," but they come with a few complexities of their own. This webinar will teach you how to use open-source solutions like Spring Cloud Stream, RabbitMQ…

In 2014, we announced the retirement of our legacy forum, forum.spring.io, in favor of providing an improved community experience on stackoverflow.com. As part of that announcement, we put our forum into read-only mode, preserving forum posts that were referenced in various Spring issue trackers.

On February 28, 2019, we plan to take the forum completely offline. In preparation for this end-of-life activity, we have gone through our issue trackers and identified links to forum.spring.io that contain supplementary information related to an issue. Based on this analysis, we have either copied…

Dear Spring community,

The Spring Cloud Data Flow team have been happy stewards of the Spring Cloud Deployer and Spring Cloud Data Flow implementations of Apache Mesos and Apache YARN.

We now feel that TrustedChoice.com will be a better home for Apache Mesos implementation of Spring Cloud Deployer and Spring Cloud Data Flow, and we are donating the projects to them to carry it forward.

The development will now be managed directly by the team (Adam J. Weigold, Phil Egelston, Justin Mathieu, and Cole Anderson) at TrustedChoice.com, as the Spring Cloud Data Flow team will no longer maintain it.

…

All good things must come to an end, and for the 1.x line of Spring Boot that means we will need to cease maintenance twelve months from today, on Aug 1st 2019.

We will keep publishing occasional 1.5.x maintenance releases up until that point and will then end the branch.

Existing Spring Boot 1.x users should plan accordingly to ensure that they have upgraded to the latest 2.x version before that date. Please also note that Spring Boot 2.0 and above requires Java 8+, so if you're running Java 6 or 7 you should also plan on upgrading your JDK.

For detailed instructions on what you'll need to do to upgrade a Spring Boot 1.5 application to 2.0, check out the migration guide…
