The Spring team has decided to change the versioning scheme for both release trains and project modules. These changes will be coming in the next release train and minor releases for each project. In fact, the changes are already present in Spring Cloud 2020.0.0-M1. Maven and Gradle do not provide the exact same version ordering, but we are working with the Gradle team to ensure the Spring scheme ends up sorted in the same way with both tools.

Release Train Version Changes

Spring has been using alphabetically ordered, themed release train versions since 2013. Release trains contain a group of…

Hi, Spring fans! Welcome to another installment of Spring Tips! In this installment, we'll revisit two topics that we've addressed in two previous videos (distributed tracing and metrics collection) in terms of the superb Tanzu Wavefront observability platform.

The first video of the two videos, as mentioned above, dating way back in early 2017, looked at distributed tracing with spring cloud sleuth and openzipkin. Spring Cloud Sleuth is an abstraction for capturing the flow of messages from one node to another. It's useful to help you see how messages move through a system. Spring cloud sleuth integrates with all the usual ingress and egress points in a Spring Boot application. Make an HTTP request using either the Restteplat or the reactive WebClient or Spring Cloud Feign? It works. Receive an HTTP request to a traditional (Servlet-based) or…

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's already April 28th, 2020. I can't even believe it.

The time sure is flying, not just since the last time we spoke in this little blog of ours, but also since I first started writing these roundups the first week of January 2011. In four short months, it'll have been ten years since I officially joined the Spring team! Crazy.

It's also the case that time has flown by since this #COVID19 crisis forced much of the world into lockdown. I am an eternal optimist, and I was wondering if this COVID19 crisis was going to have…

On behalf of the team, I'm pleased to announce Spring Data releases Neumann RC2, Moore SR7, and Lovelace SR17. This triple-feature is built on top of today's Spring Framework releases 5.2.6 (Neumann and Moore) and 5.1.15 (Lovelace).

Spring Data Neumann RC2 contains 96 new features, improvements, and fixes. Spring Data Moore SR7 ships with 40 fixes and improvements. Finally, Spring Data Lovelace SR17 includes 39 selected fixes.

Spring Data Neumann RC2 ships with numerous improvements and new features. The most interesting amongst these are:

• Query Derivation for Spring Data JDBC.
• Refinements in the reactive resource lookup for Spring Data Cassandra and Spring Data MongoDB, introducing a deferred lookup for Session with a MongoDatabase that allows for routing implementations that use the Subscriber Context.
• Embedded Types in Spring Data Cassandra
• Additional Entity Callbacks in Spring Data Elasticsearch
…

On behalf of the team and everyone who has contributed, I am pleased to announce a full round of Spring Framework releases.

Spring Framework 5.2.6 includes 46 fixes and improvements. Spring Framework 5.1.15 includes 16 selected fixes and improvements.

Maintenance releases for 5.0.x (5.0.17) and 4.3.x (4.3.27) with 12 selected fixes and improvements and 5 selected fixes and improvements respectively are also available today.

As usual, we'll follow up shortly with corresponding Spring Boot releases (2.2.7 and 2.1.14) as well as a release candidate for Spring Boot 2.3!

We are pleased to announce the release of the Spring Cloud Stream Horsham.SR4 (3.0.4.RELEASE) release train which is available as part of Spring Cloud Hoxton.SR4 and builds on Spring Boot 2.2.6 and Spring Cloud Function 3.0.6.RELEASE which was also just released.

Spring Cloud Stream Horsham.SR4 modules are available for use in the Maven Central repository.

This release contains several fixes and enhancements primarily driven by user's feedback, so thank you. For more details please follow these links:

• Spring Cloud Stream Core
• Spring Cloud Stream Rabbit Binder
• Spring Cloud Function

As mentioned, Spring Cloud Hoxton.SR4 was also released, but it only contains updates to Spring Cloud Stream and Spring Cloud Function.

Hi, Spring fans! In this episode Josh Long (@starbuxman) talks to Linux kernel hacker and Linux Real-Time patch founder Steve Rostedt on observing the Linux kernel and on what it sees when it looks at our busy Java and Spring applications.

Spring Cloud Data Flow team is pleased to announce the first milestone release of 2.5.0.RC1.

This first release candidate of 2.5.0 adds some bug fixes and the following features:

• Support application metadata as part of the Container images. Before this release, we only supported application property whitelisting when using a maven artifact.

• Support for Azure AD integration using OAuth 2.0. Spring Cloud Data Flow, Spring Cloud Skipper servers along with the Spring Cloud Data Flow shell can be configured to integrate with Azure AD for authentication and authorization.

• Removal of Scheduler task launcher component when scheduling tasks. In Spring Cloud Data Flow 2.3.x, the scheduling of tasks was designed to have an intermediate scheduler task launcher component to enhance the continuous deployment user experience. Since this component added some additional complexities and overhead on Kubernetes, the 2.5.x release removed this intermediary task launcher. We also added a migration tool to migrate the schedules from 2.3.x and 2.4.x

Hi, Spring fans! Welcome to another installment of Spring tips! in this installment, we're going to look at something that's rather foundational, and something that I wish I'd addressed earlier: configuration. And no, I don't mean functional configuration or java configuration or anything like that, I'm talking about the string values that inform how your code executes. the stuff that you put in application.properites. that configuration.

All configuration in Spring emanates from the Spring Environment abstraction. The Environment is sort of like a dictionary - a map with keys and values. Environment is just an interface through which we can ask questions about, you know, the Environment. The abstraction lives in Spring Framework and was introduced in Spring 3, more than a decade ago. up until that point, there was a focused mechanism to allow integration of configuration called property placeholder resolution. This environment mechanism and the constellation of classes around that interface more than…
