Hi Spring fans and welcome to another installment of This Week in Spring! This week I'm in Hong Kong for the amazing YOW! Hong Kong event and then it's off to Singapore for the YOW! Singapore event. If you're in either region, these conferences are world-class events from Australia and they're new in the region so I hope you'll give them a shot.

• Check out this first of many introductions to various aspects of Spring Cloud Data Flow. This first introduction, by Spring Cloud Data Flow ninja Eric Bottard, looks at the Spring Cloud Data Flow shell itself.
• Spring Cloud contributor Ryan Baxter just announced Spring Cloud Edgeware M1. The new release includes updates to the various projects as well as the new Spring Cloud Gateway project. This version is based on Spring Boot 1.5.x.
• Spring Cloud co-founder Spencer Gibb just announced Spring Cloud Finchely M2…

With the new Helm chart for Spring Cloud Data Flow for Kubernetes, there is now a much simpler way of installing the software.

Helm is a package manager for Kubernetes, similar to apt, yum or homebrew. It is very easy to install and it greatly simplifies installation of an application and its dependencies into your Kubernetes cluster. The application package contents and configuration is defined in a chart. When you install it you can override any default configuration values. Helm will install any required services in addition to the ones defined in the chart. For Spring Cloud Data Flow, you have three required services: MySQL and Redis are used as the stores for Spring Cloud Data Flow…

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I was in Beijing, China for the fabulous Spring Summit event which saw technologists from all around China descend on the capitol for a discussion of all things cloud native and Spring. Then I'm off to Shenzhen, China and Hong Kong for customer visits and the epic YOW! Hong Kong show!

• Pivotal have released a commercial version of the Concourse CI pipeline tool for Cloud Foundry. Check it, and Spring Cloud Pipelines, out!
• I liked Bruno Leite's post on error handling in a Spring Boot-based REST API.
• You might like Baeldung's post on using GraphQL with Spring Boot
• This project seems interesting, though I haven't used it yet. It lets you use ModelMapper with Spring Boot applications.
• This is a great find by community legend Tommy Ludwig who noticed that Bitbucket is now running on Spring Boot!
• This post…

On behalf of the Data Flow team, I am pleased to introduce you to the first of a hopefully long series of posts highlighting features of Data Flow and related projects.

We’ll start gently with a short video discussing the Data Flow shell and some of its features (some of them coming directly from the Spring Shell project) by yours truly.

Topics include:

• TAB completion

• Keyboard shortcuts

• Quotes handling in Spring Shell

• Quotes handling in Data Flow DSL

The reference documentation section mentioned in the video can be found here, while reference on the general Data Flow DSL is here…

Spring Boot 2 brings important changes to Actuator and I am pleased, on behalf of the team, to give you a sneak peek to what’s coming in 2.0.0.M4.

Working on a major new release gives us the opportunity to revisit some of the public contracts and improve them. We quickly felt that the endpoint infrastructure was one of them: currently, the web endpoints in the Actuator are only supported with Spring MVC (no JAX-RS support). Also, creating a new endpoint that exposes several operations requires writing quite a lot of boiler plate: you need to write a main endpoint, the Spring MVC extension (as a @RestController), a JMX MBean and the necessary auto-configuration. As of Spring Boot 2 support for a "reactive" actuator became an obvious requirement that also brings…

Hi Spring fans! Welcome to another installation of This Week in Spring. Can you believe we're already nearing the end of August?? Time sure flies!

Last week and over the weekend I was in Hangzhou, China visiting with Alibaba, talking to a few of the teams using Spring Boot and Spring Cloud at China-scale.

This week I'm in Shanghai, China, where I've been talking to customers and spending a few days with the teams at Microsoft China who are working on the Spring Boot and Pivotal Cloud Foundry integrations for Microsoft Azure. They're doing some amazing work and it's been an honor to hang out with them. Check out all the cool Spring Boot starters that they've built for the various Azure services…

Hi Spring fans and welcome to another installment of This Week in Spring! It's been a busy week! I started last week talking to a group of developers in North Carolina, then gave a VJUG presentation with Matt Raible in San Francisco, then spoke to developers in Saint Louis, then flew to New York City to shoot a video on continuous delivery for three days in a hot studio (over the weekend no less!) and now as I wing back to San Francisco I look forward to spending a blissful 14 hours on the ground before I'm off to Asia (Hangzhou, Shanghai, Beijing, Shenzhen, Hong Kong, and Singapore) for about…

Hi Spring fans and welcome to another installment of This Week in Spring! This week I'm presenting with my buddy Matt Raible on the VJUG (Virtual JUG) on Progressive Web Applications with Spring Boot and Angular 4, this Wednesday. Join us! Then it's off to New York City, NY where I'll be working with my buddy Marcin Grzejszczak on an exciting new project.

• Spring IO Platform lead Andy Wilkinson just announced Spring IO Platform Brussels-SR4. This release revises the versions for Spring Batch 3.0.8, Spring Boot 1.5.6, Spring Data Ingalls SR6, Spring Framework 4.3.10, Spring Integration 4.3.11, and Spring Retry 1.2.1.
• The first milestone of Spring Cloud Data Flow 1.3.0 is out! Lots of nice new features including a flashy new user interface based on Angular 4, better documentation, better test coverage, and so much more.
• Spring Cloud Pipelines lead Marcin Grzejszczak just announced Spring Cloud Pipelines 1.0.0.M6. This release supports a powerful mechanism called pipeline descriptors…

Update: see also Spring Fu experimental project.

Since our original announcement (very well received by the community!) of official Kotlin support in Spring Framework 5, we have continued to work towards even stronger Kotlin support in conjunction with recent refinements in Spring WebFlux.

In order to demonstrate these features, and how they could be used together, I have created a new spring-kotlin-functional demo application which is a standalone Spring WebFlux application, developed in Kotlin, with Mustache template rendering, JSON REST webservices and Server-Sent Events streaming…
