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.

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.

Slides: http://www.slideshare.net/SpringCentral/spring-batch-performance-tuning

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.

G&G Special Topics

Slides: http://www.slideshare.net/SpringCentral/reactive-grails

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.

Core Spring Track

Slides: http://www.slideshare.net/SpringCentral/testing-with-spring-framework-4x

The Spring Framework has undergone a lot of innovation in the 4.0 and 4.1 releases, and so has its testing support. Join Spring Test component lead Sam Brannen in this talk to discover what's new in Spring's testing support in 4.0 through 4.1. This talk will provide attendees an overview of what's been deprecated, what's changed, and what's been introduced in Spring's testing support over the last two years, with real life examples and tips for best practices. Highlights include using SocketUtils to scan for free TCP & UDP server ports, the ActiveProfilesResolver API, meta-annotation support for test annotations including attribute overrides, best practices with TestNG, using Groovy scripts to configure an ApplicationContext for integration tests, improvements to SQL script execution and embedded databases, the new TestContext framework bootstrap strategy, programmatic transaction management in tests, and more.

Core Spring Track

Alright, so maybe "bootiful" won't ever work, but we tried, and it was worth it too because you're reading this. Spring Boot, the new convention-over-configuration centric framework from the Spring team at Pivotal, marries Spring's flexibility with conventional, common sense defaults to make application development not just fly, but pleasant! Join Spring developer advocate Josh Long and Spring Boot co-lead Phillip Webb for a look at what Spring Boot is, why it's turning heads, why you should consider it for your next application (REST, web, batch, big-data, integration, whatever!) and how to get started.

More Groovy Track

Slides: http://www.slideshare.net/SpringCentral/traits-design

Groovy 2.3 introduces the concept of traits in the language. Traits look like interfaces, but allow the developer to add both implementation and state into it. It introduces multiple inheritance in the language while avoiding the diamond problem. Traits will let you rethink the way you design APIs in Groovy, by favoriting composition of behaviors.

Speaker: Andy Wilkinson

An API's documentation is a vital part of making it easy to understand and easy to use. RESTful APIs are no different. In this webinar we'll look at what should be included in your RESTful API's documentation and, just as importantly, what should be omitted. To illustrate this we'll look at some real-world examples of good and bad API documentation. We'll look at some of the problems and limitations of choosing a tool like Swagger to produce your API's documentation and conclude by looking at some alternatives that are better-suited to producing documentation that your users will love.
