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…

The Spring Cloud Data Flow team is pleased to announce the release of 1.4.0 RC1. Follow the Getting Started guides for Local Server, Cloud Foundry, and Kubernetes.

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…

Auto-configuration is one of the most powerful features of Spring Boot. Tests for auto-configuration classes usually follow the same pattern. Most tests start up an ApplicationContext with the auto-configuration class under test and depending on the test, also load additional configuration to simulate user behavior. The recurrence of this pattern can add a lot of repetition in the code base.

Spring Boot 2.0 provides a suite of new test helpers for easily configuring an ApplicationContext to simulate auto-configuration test scenarios. The following example configures an ApplicationContextRunner to test the UserServiceAutoConfiguration…

We are pleased to announce the release of Spring Batch 3.0.9.RELEASE and 4.0.1.RELEASE via Maven Central, Github, and the Pivotal download repository.

These two maintenance releases address a number of bug fixes, enhancements and documentation updates. For a complete list of changes, please refer to the change logs for 3.0.9 and 4.0.1. Many thanks to all of those who submitted pull requests that went into these releases.

Please note that the next patch version, 3.0.10.RELEASE, will be the last maintenance release of the 3.x line. We strongly recommend users to migrate to the latest and…

Spring Web Flow 2.5 is now GA and available for use. This release provides an upgrade path for applications using Web Flow to Spring Framework 5 with Java 8, Servlet 3.1, Hibernate 5, Tiles 3, and JSF 2.2 as minimum requirements.

One of the key features in Spring Security 5 is support for writing applications that integrate with services that are secured with OAuth 2. This includes the ability to sign into an application by way of an external service such as Facebook or GitHub.

But with a little bit of extra code, you can also obtain an OAuth 2 access token that can be used to perform authorized requests against the service’s API.

In this article, we’re going to look at how to develop a Spring Boot application that, using Spring Security 5, integrates with Facebook. You can find the complete code for this article at https://github.com/habuma/facebook-security5…
