Modern JavaScript frameworks have become quite sophisticated. Unfortunately, they have also become quite complicated. The demos and sample projects for these frameworks look deceptively simple. However, to build and deploy real applications, developers must scaffold, configure, and maintain a tremendous amount of intricate machinery. Until recently, the Java world wasn't very different. Spring Boot finally made it easy to create stand-alone, production-grade Spring Applications that can you can "just run". Can we do the same for JavaScript? Yes, we can! Introducing RaveJS. Rave eliminates configuration, machinery, and complexity. Stop configuring and tweaking machinery such as file watchers, minifiers, and transpilers just to get to a runnable app. Instead, go from zero to "hello world" in 30 seconds. In the next 30 seconds, easily add capabilities and frameworks to your application simply by installing *Rave Extensions* and *Rave Starter* packages from npm and Bower, the leading JavaScript package managers. Finally, install additional *Rave Extension* packages to apply your favorite build, deploy, and testing patterns.

JHipster focuses on generating a high quality application with a Java back-end using an extensive set of Spring technologies; Spring Boot, Spring Security, Spring Data, Spring MVC (providing a framework for websockets, REST and MVC), etc. an Angular.js front-end and a suite of pre-configured development tools like Yeoman, Maven, Gradle, Grunt, Gulp.js and Bower. JHipster creates a fully configured Spring Boot application with a set of pre-defined screens for user management, monitoring, and logging. The generated Spring Boot application is specifically tailored to make working with Angular.js a smoother experience. Join Julien for a quick-live coding session to build a simple application, and deploy it to Cloud Foundry.

Polymer is the latest web framework out of Google. Designed completely around the emerging Web Components standards, it has the lofty goal of making it easy to build apps based on these low level primitives. Along with Polymer comes a new set of Elements (buttons, dialog boxes and such) based on the ideas of "Material Design". These technologies together make it easy to build responsive, componentized "Single Page" web applications that work for browsers on PCs or mobile devices. But what about the backend, and how do we make these apps secure? In this talk Scott Deeg will take you through an introduction to Polmyer and its related technologies, and then through the build out of a full blown cloud based app with a secure, RESTful backend based on Spring REST, Spring Cloud, and Spring Security and using Thymeleaf for backend rendering jobs. At the end he will show the principles applied in a tool he's currently building. The talk will be mainly code walk through and demo, and assumes familiarity with Java/Spring and JavaScript.

Spring Data REST bridges the gap between the convenient data access layers provided by Spring Data's repository abstraction and hypermedia-driven REST web services, effectively taking out the boilerplate needed during implementation. This talk will give a quick overview of the project, explain fundamental design decisions and introduce new features of the latest version (namely service documentation and discoverability). We will then look at the Spring-A-Gram sample application (built using Spring Data REST), focusing on the implementation of the frontend bits and pieces.

Core Spring Track

In this Panel session, each of these presenters will have 20 minutes to respond to the question: tell us about your experiences with Spring Boot? Following that is about 30 minutes of moderated panel discussion. Erdem Gunay from Turkcell will present his experience of re-writing a Mobile BaaS originally written with Spring 3.x. He wrote the service from scratch using Boot in one week, integrating spring security, elasticsearch, mongodb, camel, angular.js, for the win: 40x throughput, 100% availability - zero crashes, 3x the users - used on 300k mobile devices. Tim Hobson from Intuit will present his lessons learned from using with Boot - he will take you through what configuration was necessary, what needed to be built, and how the project leveraged Boot to minimize cross-cutting code and configuration, maximize testability, and focus on the application domain. Zach will present a view of Boot from the hospitality industry, where they are using JAX-RS, DropWizard, and Spring Boot to create micro-service applications. He will help you understand which dropwizard-spring integrations work, and which one's don't, what to watch out for, and how to integrate your Spring applications into dropwizard whether you configure your Spring applications with xml, annotations, and/or java config files.

Speakers: Michael Hunger, Lorenzo Speranzoni - Neo Technology

Slides: http://www.slideshare.net/SpringCentral/artistic-spring-data-neo4j-3x-with-spring-boot-and-van-gogh

This session will show, how easy it is to get started with Spring Data Neo4j using Spring Boot. After a quick introduction of the concepts behind the Neo4j NoSQL graph database and its Spring Data integration library, we will discuss the general approach used in Spring Data Neo4j and highlight the exciting, new features of the new 3.x releases which now works with the most recent Neo4j 2.x versions. During the session we'll demonstrate the development steps of an exciting and unusual application - tracking an famous' artists journey connecting him to the places, paintings, people and other aspects that influenced him. Having this data in a graph allows us to find new insights and conclusions as well as quickly adding different aspects to it. This application will use Spring Boot and Spring Data Neo4j to get started quickly. We import the data, look at it as a graph visualization and then build a web-application using Spring Boot's supporting infrastructure. As a final step we show how evolving this application from being a just Neo4j client application to a REST extension of the Neo4j server requires only a few steps and can leverage Spring Data REST to provide the neccessary endpoints for consumers.

In this presentation we will examine various scalability options in order to improve the robustness and performance of your Spring Batch applications. We start out with a single threaded Spring Batch application that we will refactor so we can demonstrate how to run it using: * Concurrent Steps * Remote Chunking * AsyncItemProcessor and AsyncItemWriter * Remote Partitioning Additionally, we will show how you can deploy Spring Batch applications to Spring XD which provides high availability and failover capabilities. Spring XD also allows you to integrate Spring Batch applications with other Big Data processing needs.

Worried about Big Data and the challenges inherent in making a real application? You don’t have to worry anymore! Spring XD provides a one-stop shop solution that spans traditional enterprise to Big Data use cases - both batch and streaming. It's important to choose the right tool for each use-case, which is why Spring XD integrates with technologies such as Spark, Reactor and RxJava to demonstrate the flexibility and the unified programming model to support complex data computation use-cases. In this webinar, we'll show you how to develop data-driven use cases much faster than other big data solutions on the out of the box XD runtime.

The natural tendency for application developers is to construct their code in a procedural, synchronous, monolithic pattern. Veteran developers know that this leads to error prone, unscalable, slow software - yet it is alarmingly prevalent. There have been several architectural patterns that have risen over the years which have attempted to mitigate this problem. One of the most popular has been Service Oriented Architecture, which involves breaking the monolithic application into a distributed system of several smaller services. In this talk, I argue that SOA is a decent start, but not nearly good enough. I will discuss the tenants of the Reactive Pattern and the importance of moving away from Monolithic to Reactive architectures. We will discuss the various Groovy-friendly technologies that allow us to build distributed, micro-service based applications and cover effective communication strategies between each service. We will see how being Reactive is the only viable architecture for large, efficient, scalable systems. If Reactive is new to you, this should be an excellent introduction.
