6:10-7:00: Spring Boot: More Spring, Less Configuration – Craig Walls

Spring offers a number of configuration options: XML configuration, Java configuration, and Groovy configuration to name a few. To some degree, component-scanning and autowiring help eliminate some explicit configuration. But in general most Spring applications require some essential “bootstrap” configuration to enable key functionality. What’s the right way to build Spring applications when there are so many choices?
What if I told you that configuration was optional?
What if I told you that it is entirely possible to write a Spring application that is short enough to broadcast *twice* in a single tweet?
Spring Boot is an exciting new project that makes it extremely easy to create stand-alone, production-ready Spring applications. Spring Boot takes an opinionated approach to configuring Spring, making it possible to create Spring applications with little or, in some cases, no Spring configuration at all!

7:15-8:45: Spring Data – Craig Walls

This session starts with a high-level look at all that the Spring Data project has to offer. Then we’ll dive deeper into a few select Spring Data modules, including Spring Data Neo4j, Spring Data MongoDB, Spring Data Redis, Spring Data JPA, and Spring Data JDBC Extensions.
In recent years, there has been a renewed interest in how data is stored. Although RDBMS has long been treated as a one-size-fits-all solution for data storage, a new breed of datastores has arrived to offer a best-fit solution. Key-value stores, column stores, document stores, graph databases, as well as the traditional relational database are options to consider.
With these new data storage options come new and different ways of interacting with data. Even though all of these data storage options offer Java APIs, they are widely different from each other and the learning curve can be quite steep. Even if you understand the concepts and benefits of each database type, there’s still the huge barrier of understanding how to work with each database’s individual API.
Spring Data is a project that makes it easier to build Spring-powered applications that use new data, offering a reasonably consistent programming model regardless of which type of database you choose. In addition to supporting the new “NoSQL” databases such as document and graph databases, Spring Data also greatly simplifies working with RDBMS-oriented datastores using JPA.

About Craig Walls:

Craig Walls has been professionally developing software for over 17 years (and longer than that for the pure geekiness of it). He is a senior engineer with SpringSource as the Spring Social project lead and is the author of Spring in Action and XDoclet in Action (both published by Manning) and Modular Java (published by Pragmatic Bookshelf). He’s a zealous promoter of the Spring Framework, speaking frequently at local user groups and conferences and writing about Spring and OSGi on his blog. When he’s not slinging code, Craig spends as much time as he can with his wife, two daughters, 5 birds and 3 dogs.

7:15-8:30: Reducing Java Enterprise Testing to Child’s Play – Dan Allen

This talk unveils the missing link in enterprise Java development: simple, portable integration tests. For many, working in enterprise Java has long been an arduous undertaking because of this void. While development life is simple with unit tests and mocks, they only take you so far. Eventually, you need to validate how your components interact and operate in their intended environment–you real need integration tests. Yet, writing integration tests has meant assuming the burden of bootstrapping all or part of your infrastructure. That’s time lost and it places a mental barrier on testing. Arquillian and ShrinkWrap, two new projects from the JBoss Community, partner to tear down this barrier and reduce Java enterprise testing to child’s play. Come experience how.

Arquillian, a container-oriented testing framework layered atop TestNG and JUnit, brings your test to the runtime rather than requiring you to manage the runtime from your test. Picking up where unit tests leave off, Arquillian enables you to test real components that rely on real enterprise services in a real runtime.

We’ll look at how the fluent API provided by ShrinkWrap is used to package a test archive, giving developers fine-grained control over which resources are available to be tested. We’ll show examples of how the test archive is deployed and executed inside standalone, embedded and remote containers. You’ll witness how RPC-style (or local, if applicable) communication between the test runner and the environment negotiates which tests are executed and reports back the results. You’ll walk away confident that you can write integration tests just as you would a unit test and the test is portable to multiple environments (containers).

What’s the secret? This talk reveals how Arquillian simplifies integration testing by providing a component model for tests, just as Java EE 5 simplified server-side programming by providing declarative services for application components. The test component model consists of container lifecycle management, test enrichment (dependency injection), container deployment and in-container test execution. Using a component model means your tests are portable and able to move between different environments, from single embedded or remote to multi-server to multi-cloud nodes.

About Dan Allen:

As Principal Software Engineer at Red Hat, Dan serves as the JBoss Community liaison, leads the JBoss Testing Initiative and is a member of the Arquillian, ShrinkWrap and JBoss Forge projects. He authored Seam in Action (Manning), served as a representative for Red Hat on the JSR-314 Expert Group (JSF 2.0), writes for IBM developerWorks and NFJS magazine and is an internationally recognized speaker. He’s appeared at major industry conferences including JavaOne, Devoxx, NFJS, JAX and Jazoon and has received recognition as a JavaOne Rock Star, a JBossWorld Top Presenter and a JAX Hall of Fame speaker.

To colleagues, Dan’s known for his hard work and passion for Open Source technologies. His technical expertise includes Java frameworks (Seam, CDI, Weld, JSF, EJB 3, JPA, Hibernate, Spring), testing frameworks (Arquillian, JUnit, TestNG, Selenium), build tools (Maven 2, Gradle, Ant) and web development (Ajax, JavaScript, CSS) and more.

6:10-6:55: Spring Insight, What Just happened? by Derek Beauregard

Spring Insight answers the question “What just happened?” (in my web application). It is a free SpringSource Web application that gives you real-time visibility into application behavior and performance.
In development and testing stages, developers can use Spring Insight to verify immediately whether their newly-written code is behaving as designed. QA engineers can pinpoint specific causes for “what just happened” and relay detailed information to developers.
Stress testing an application typically tells you which URL areas are slow. By combining Spring Insight with your existing tools (such as JMeter), you can see not only which URLs are slow, but why, thus accelerating your time to production.
All of this is done through automatic, no configuration and zero coding, code introspection that works with the Spring Framework, Spring MVC, JPA, Hibernate and more. And its extensible, so you can build your own adaptors for your technology.

About Derek Beauregard:

Derek Beauregard is a technologist at heart with over 10 years experience in the industry. He is currently working as a Sales Engineer in the vFabric (Spring Source) division of VMware. Prior to this role he was a consultant in the vFabric PSO organization designing and implementing vFabric/Spring based solutions for VMware’s customers across multiple verticals. His work has concentrated lately on Application Modernization, Platform as a Service (PaaS), and Big/Fast/Flexible data. Derek is based out of Denver, CO.

Java – Groovy integration just works, for most part. Calling into Java code from Groovy is pretty straight forward. Calling into Groovy from Java is easier than you may think (and that’s the hard part!). There are a few rough edges you will run into when you try to call from Groovy into other languages. In this presentation, we will take a look at integration mechanisms and how to work around the few challenges you may run into.

In this presentation we will explore patterns that allow us to make better use of closures and functional style of programming.
