What is it?

Micrometer is a dimensional-first metrics collection facade whose aim is to allow you to time, count, and gauge your code with a vendor neutral API. Through classpath and configuration, you may select one or several monitoring systems to export your metrics data to. Think of it like SLF4J, but for metrics!

Micrometer is the metrics collection facility included in Spring Boot 2’s Actuator. It has also been backported…

On behalf of the community, I’m pleased to announce the release of Spring Security OAuth 2.3.0.RELEASE.

The Spring Security SAML project team is proud to announce our latest 1.0.4.RELEASE. This maintenance release pushes its dependencies to the latest known working version while staying backwards compatible.

This release requires an additional Maven repository to download the latest version of the not-yet-commons-ssl dependency.

Moving forward we will be working on our 2.0.0 release. This release aims to provide an easy upgrade path for users of the 1.0.x releases while modernizing the underlying dependencies for easy up keep.

Feedback and contributions are always appreciated. Stay tuned.

We are pleased to announce the first milestone release of Spring Cloud Open Service Broker 2.0.0.

This project was formerly named Spring Cloud - Cloud Foundry Service Broker. A lot has changed in the few years since that project was released. The service broker API that the project implements is no longer specific to Cloud Foundry but has been donated to the Open Service Broker API project and is implemented by Kubernetes and other platforms. The new project name reflects this evolution and openness.

In addition to a new name, some highlights of the 2.0 version are:

• Requires Java 8, Spring Framework 5, and Spring Boot 2
• Supports inclusion in either a Spring MVC or a Spring WebFlux application
• Provides improved Spring Boot auto-configuration

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in blizzard-besieged Boston, Massachusetts, for the epic Spring One Tour Boston event. Unfortunately, due to this crazy snow storm / blizzard, the event's been postponed one day as we all grapple with the weather. Hope you were able to join the Spring Boot 2.0 launch webinar! If not the replay will be available here and don't forget to check out the launch blog!

Snow or no snow! The show must go on, at least here on the Spring blog, so without further ado:

• The Reactor team is looking for a motivated new engineer to join the team - apply now!
• Spring Cloud Data Flow ninja Gunnar Hillert has just announced Spring Cloud Data Flow 1.4 RC1
• Spring IO Platform Cairo-RC1 lead Andy Wilkinson has just announced the latest updates, including Spring Boot 2.0. Check it out and make sure works as you expect it to.
• I love this post by Spring team legend Stéphane Nicoll on upgrading the Spring Initializr (http://start.spring.io) to Spring Boot 2.0.
• The Spring Data JDBC project has added @Modify for marking queries that perform DML or DDL. Modifying queries will return type boolean or Boolean…

Spring Boot 2 was released recently and the production instance of Spring Initializr (start.spring.io) was upgraded to Spring Boot 2 the same day.

In this post, I'd like to walk you through the process of upgrading a Spring Boot 1.x app to Spring Boot 2.

Release notes and migration guide

A good first step is to get yourself familiar with the main changes in Spring Boot 2 by reading the migration guide and the release notes.

Build upgrade

If you are using Maven and the spring-boot-starter-parent, you need to be aware that several plugins are going to be updated as part of the upgrade. If you're not using the parent, it is worthwhile to inspect your build and upgrade the plugins that you are using. Spring Initializr is built with Maven so the easiest way is to scan spring-boot-dependencies…

It's my pleasure to announce that Spring IO Platform Cairo-RC1 is now available from the Spring milestone repository. The Cairo generation of the Platform builds on top of Spring Framework 5.0 and Spring Boot 2.0 and requires Java 8.

Following are the release highlights:

Stream Deployment UX

In Skipper mode, we have added a brand new stream deployment builder form to simplify the selection of platform and the properties while deploying a stream. The options include override to the deployment platform and the deployer, application and global properties for the streaming pipeline.

Docker Compose for Development

To simplify the getting started experience for the Local Server, we have added the Docker Compose support, which when run as a single command from the CLI, it will automatically provision the latest release of the Local-server along with Apache Kafka for messaging…
