For this session we will explore the power of Spring XD in the context of the Internet of Things (IoT). We will look at a solution developed with Spring XD to stream real time analytics from a moving car using open standards. Ingestion of the real time data (location, speed, engine diagnostics, etc), analyzing it to provide highly accurate MPG and vehicle range prediction, as well as providing real time dashboards will all be covered. Coming out of this session, you’ll understand how Spring XD can serve as “Legos®” for the IoT.

Core Groovy Track

Java is a good all-purpose programming language, but does that mean it's the best tool for all jobs?

Core Groovy Track

Slides: http://www.slideshare.net/SpringCentral/groovybrowserautomation-2gx2014

GEB (pronounced 'jeb') is a browser automation solution. It brings together the power of WebDriver, the elegance of jQuery content selection, the robustness of Page Object modelling and the expressiveness of the Groovy language.

Welcome to another installment of This Week in Spring! This week, I'm in São Paulo, Brazil, where I presented a workshop on building cloud-native applications - specifically microservices - with Spring Boot, Spring Cloud and Cloud Foundry (via Pivotal Web Services).

• Spring Data lead Oliver Gierke has just announced Spring Data Fowler has gone GA, packed with lots of advanced Java 8 features, as well!
• The agenda for the Spring IO show in Barcelona, Spain is now available! Check it out!
• Done with the microservices hype? Then let's get practical on April 21st. I'll be talking about how Spring Cloud integrates service registration (e.g.: Eureka, Consul, or Zookeeper), declarative REST clients (with Netflix's Feign), reactive programming and the circuit breaker pattern with Hystrix to support easy, robust service-to-service invocations.
• Marius Bogoevici and Mark Pollack are teaming up for a webinar on Tues April 28th about Reactive data-pipelines with Spring XD and Kafka…

Note: the source code and test for this blog continue to evolve, but the changes to the text are not being maintained here. Please see the tutorial version for the most up to date content.

In this article we continue our discussion of how to use Spring Security with Angular JS in a "single page application". Here we show how to use Spring Session together with Spring Cloud to combine the features of the systems we built in parts II and IV, and actually end up building 3 single page applications with quite different responsibilities. The aim is to build a Gateway (like in part IV) that is used not only for API resources but also to load the UI from a backend server. We simplify the token-wrangling bits of part II by using the Gateway to pass through the authentication to the backends. Then we extend the system to show how we can make local, granular access decisions in the backends, while still controlling identity and authentication at the Gateway. This is a very powerful model for building…

On behalf of the Spring Data team I'd like to announce the availability of the GA version of Spring Data release train Fowler.The release ships almost 400 tickets solved.

The most core theme of the train is advanced support for Java 8: the MongoDB and JPA modules now support Streams as return type for repository methods and we now support non-time-zoned JDK 8 date/time types our of the box and also integrate with the Java 7 back-port of that API.

Spring Data MongoDB ships with compatibility for the 3.0 version of the server and the corresponding driver version. Spring Data Gemfire now supports…

This week I'm in São Paulo, Brazil presenting at QCon SP. I had an interesting discussion with someone who loves Spring's REST stack, but wondered if there was something more efficient than plain-ol' JSON. Indeed, there is! I often get asked about Spring's support for high-speed binary based encoding of messages. Spring's long supported RPC encoding with the likes of Hessian, Burlap, etc., and Spring Framework 4.1 introduced support for Google Protocol Buffers which can be used with REST services as well.

From the Google Protocol Buffer website:

Protocol buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages...

Spring Boot STS Tutorial

Spring Tool Suite 3.6.4 was just released last week. This blog post is a tutorial demonstrating some of the new features STS provides to create and work with Spring Boot applications.

In this tutorial you'll learn how to:

• create a Simple Spring Boot Application with STS
• launch and debug your boot application from STS
• use the new STS Properties editor to edit configuration properties.
• use @ConfigurationProperties in your code to get the same editor support for your own configuration properties.

Creating a Boot App

We use the "New Spring Starter" wizard to create a…

Developing for the Cloud Track

Slides: http://www.slideshare.net/SpringCentral/apps-data-cloud-what-does-it-all-mean

Big Data. Fast Data. NoSQL. NewSQL. We've experienced something of a renaissance in the storage and processing of data in the last decade of computing after years of "Relational Winter." We're now entering into the next phase of this evolution: the convergence of data and the cloud. Much of this revolution has arrived on the coattails of data fabrics designed for horizontal scale-out on commodity hardware. Cloud platforms, especially PaaS platforms like Cloud Foundry, allow us to provision the requisite virtual hardware on-demand, removing the last mile of overhead in assembling scale-out data platforms. Coupling PaaS with microservice architectures and polyglot persistence allows developers to design systems utilizing stores uniquely designed for specific write, process, and query patterns. Leveraging the Lambda Architecture combination of real-time analytics platforms coupled with scale-out batch processing systems like Hadoop give us the ability to always ask questions of all of our data. In this talk will look at various Spring projects that allow us, coupled with Cloud Foundry, to uniquely position ourselves to take advantage of this convergence: Spring Boot: the opinionated framework for microservice development Spring Data: the access layer for SQL, NoSQL, NewSQL, and Hadoop Reactor: the foundation for reactive fast data applications on the JVM Spring XD: the platform for data ingest, real-time analytics, batch processing, and data export We'll tie all of these projects together in a suite of applications running on Cloud Foundry and Hadoop, closing the Apps/Data/Cloud loop.
