We are pleased to announce that Spring Cloud Task 2.1.0.M2 is now available on Github and the Pivotal download repository. Many thanks to all of those who contributed to this release.

What's New?

Spring Cloud Task 2.1.0.M2 is intended to be the version of the framework aligned with Spring Boot 2.1.0. Updates from 2.1.0.M1 include:

• Update all dependencies.
• By popular demand, @EnableTask is back.
• Bug Fixes.

Let's walk through these updates in more detail.

@EnableTask is back

By popular demand, @EnableTask is back, with a twist! In this case, AutoConfiguration is still being used to create the TaskExplorer, TaskConfigurer, and other beans but does not create the TaskLifecycleListener (the bean that adds the Task Lifecycle to your application). The TaskLifecycleListener bean is created when a user adds the @EnableTask to…

Hi Spring fans! In this installment of Spring Tips we look at using the nascent R2DBC abstraction supporting reactive SQL data access and then introduce the Spring Data R2DBC project that supports typical Spring Data idioms like repositories.

Hi Spring fans!

Welcome to another installment of This Week in Spring! I just wrapped up the last two talks or workshops I'll do this year. Yesterday we spent four hours looking at Reactive Spring and today we spent four hours looking at Spring Boot and Kotlin. I love doing these sorts of trainings because I really get to dive deep on topics with my audiences. It's, truly, one of the rare pleasures in an otherwise hectic schedule. Needless to say, I am super relaxed and happy as I write this and I hope you are too!

You realize it's already December 18th, 2018, already? Gee time flies when you're having fun! The next installment of This Week in Spring is on the 25th, which, for some in the world, is the holiday Christmas. If that includes you, then let us be the first to …

I’m pleased to announce the first release candidate of Spring CredHub 2.0.0, available now in the Spring milestone repository. A GA release of Spring CredHub 2.0.0 will be available in a few weeks.

CredHub

CredHub provides centralized credential management to the Cloud Foundry platform. CredHub implements an HTTP API to securely store, generate, retrieve, and delete credentials of various types.

Spring CredHub provides a Java binding for the CredHub API, making it easy to integrate Spring applications with CredHub.

What’s New

The 2.0.0 release includes the following enhancements:

• Supports CredHub server versions 1.x and 2.x, and the CredHub v1 and v2 APIs

• Provides compatibility with Spring Framework 5.1 and Spring Boot 2.1

• Addition of a reactive interface using Reactor

On behalf of the community, I am pleased to announce that the Release Candidate 1 (RC1) of the Spring Cloud Greenwich Release Train is available today. The release can be found in Spring Milestone repository. You can check out the Greenwich release notes for more information.

End of Life (EOL) Reminder

The Dalston release train will reach EOL status at the end of 2018.

Notable Changes in the Greenwich Release Train

This milestone is compatible with Spring Boot 2.1.1.RELEASE. Updates were made across the projects for Java 11 compatibility.

Go to the Greenwich.RC1 github project to see all…

It’s my pleasure to announce the first milestone of Spring Data R2DBC. Spring Data R2DBC is Spring's client project for R2DBC. With Spring Data R2DBC you get end to end reactive ad-hoc query execution and Spring Data repositories for relational databases.

Spring Data R2DBC embraces functional-reactive integration of relational databases by providing DatabaseClient as its central abstraction. The following example shows how to bootstrap DatabaseClient without spinning up a Spring context:

PostgresqlConnectionFactory connFactory = new PostgresqlConnectionFactory…

Performance has always been one of the top priorities of the Spring Engineering team, and we are continually monitoring and responding to changes and to feedback. Some fairly intense and precise work has been done recently (in the last 2-3 years) and this article is here to help you to find the results of that work and to learn how to measure and improve performance in your own applications. The headline is that Spring Boot 2.1 and Spring 5.1 have some quite nice optimizations for startup time and heap usage. Here’s a graph made by measuring startup time for heap constrained apps:
