This Week in Spring - August 29th, 2017

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!


This Week in Spring - August 22nd, 2017

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.


Introducing Actuator Endpoints in Spring Boot 2.0

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 several new challenges.


This Week in Spring - August 15th, 2017

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 four weeks! I’m not the only who’s been busy, though! As usual, we’ve got a lot to cover this week so let’s get to it!


This Week in Spring - August 8th, 2017

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.


This Week in Spring - August 1st, 2017

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I’m in Nashville, TN, for a meetup presentation on Reactive Spring and then it’s off to Kansas City, KS for a replay of the same talk. Both times I’ll be joined by pal Mark Heckler. If you’re in either of those cities, don’t miss this!

I’m working on the next installments of Spring Tips: what would you like to see covered? Let me know on Twitter on @SpringTipsLive.

This week we have a truly massive good many things to look at so let’s get started!


Spring Framework 5 Kotlin APIs, the functional way

Update: see also Spring Framework 5 Kotlin support reference documentation.

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 capabilities. Don’t hesitate to send us feedbacks and proposals before Spring Framework 5 release expected in September.
