To stay competitive, enterprises are scrambling to find ways to rapidly deliver applications that are a pleasure to use on a wide range of devices. Microservice architectures, continuous delivery and the cloud can give businesses the agility to transform into great software businesses, but how do you actually turn those buzzwords into reality? Here we present our take on a solution. Using Spring Boot, Java 8’s Nashorn JavaScript engine, and Cloud Foundry, we’ve created a framework that makes it really easy to deliver API’s to support the rich and highly contextualized experiences that users expect in world class applications. We’d like to share with you what we’ve built, and what we’ve learned along the way.

The world of client-server has changed. The traditional application of REST is no longer the best fit. We're depolying applications into a world where users expect responsive UIs, on all their devices, even while disconnected. We're deploying into a world where connection latency, mobile radio usage and battery life have become primary concerns. Differential Synchronization (DS) is an algorithm that syncs data across N parties, even in the face of dropped connections, offline devices, etc. It makes more efficient use of connections by batching and sending only changes, in both directions, from client to server and from server to client. We’ll look at how it can be used with JSON Patch to synchronize application data between clients and servers over HTTP Patch, WebSocket, and STOMP, and how it can be integrated into the Spring ecosystem.

In this article we look at how to bind a Spring Boot application to data services (JDBC, NoSQL, messaging etc.) and the various sources of default and automatic behaviour in Cloud Foundry, providing some guidance about which ones to use and which ones will be active under what conditions. Spring Boot provides a lot of autoconfiguration and external binding features, some of which are relevant to Cloud Foundry, and many of which are not. Spring Cloud Connectors is a library that you can use in your application if you want to create your own components programmatically, but it doesn't do…

I'm pleased to announce the release of Spring Social Facebook 2.0.1.RELEASE. This maintenance release addresses a handful of bugs that were discovered following the 2.0.0.RELEASE two weeks ago. For complete details regarding this release, see the changelog.

Note that if you're using Spring Social Facebook with Spring Boot, the Spring Boot starter for Spring Social Facebook still references 1.1.1.RELEASE. But you can override that by explicitly declaring the 2.0.1.RELEASE dependency in your Maven or Gradle build. See the Spring Social Showcase/Spring Boot example to see how this is done.

I'm pleased to announce the release of Spring Security 4.0.1.RELEASE. This release is the first maintenance release of the 4.0 line and focusses on fixing any major issues that were found in the new release. For complete details on the release, refer to the Change Log.

We are pleased to announce the release of Spring Security Kerberos 1.0.0.RELEASE. I would like to start by saying thank you for all community members who helped us by either creating PR's for new features or simply providing feedback.

Here is a guick summary of changes what went through with two release candidates and a GA release:

• We did a lot of housekeeping to put a whole project up-to-date due to a long overdue from a first milestone.
• Spring team added KerberosRestTemplate while all other new features came from a community.
• Community contributions are:
  • KerberosLdapContextSource which allows to authenticate against Windows AD with existing Kerberos credentials to get more info about a logged-in user.
  • Tweaks to Kerberos negotiation which allows better interoperability with WinRM.
  • Changes how SpnegoEntryPoint is used which allows to fallback to other authentication methods if Kerberos negotiation fails.
• …

Welcome to another installment of This Week in Spring! This week I'm in Bangalore, India, at the Great Indian Developer Summit. Lots of the Spring Team are at JAXConf in Germany this week as well.

A friendly reminder, if you're in the south west region of Europe, and Barcelona, Spain, specifically, and looking for fun in the sun, I can think of no better option than Spring I/O Conference, which is next week. Don't miss the many great talks from many amazing Spring team and Spring community members. I'll be there and looking forward to meeting and seeing you all!

Without further ado, let's get…

Remember the epic Java Puzzlers? Here’s the Groovy version, and we have some neat ones! Even though we are totally a Grails shop here at JFrog, some of these had us scratching our heads for days trying to figure them out. And there is more! Contributions from the truly Groovy senseis, including @glaforge, @aalmiray, @tim_yates, @kenkousen make this talk an unforgettable journey to Groovy's O_O.
