Speaker: Ben Hale

As data-driven applications become more widespread, the services that provide the data are becoming more critical. Most commonly these data services are exposed via REST-ful APIs. This session describes what exactly makes a service REST-ful, how to implement a REST-ful API using Spring, and how to test that API.

Make sure to check out Ben's follow on talk from SpringOne2GX2013: REST-ful API Evolution for a great discussion of API loose coupling with HATEOAS.

Presenter: Josh Long, Pivotal

A brief (20 minute) interview with Josh Long doing some live hacking with Spring Boot, Spring MVC and Groovy. Check out the live hack - creating a simple, paramaterized RESTful service. Check out Josh as he struggles (and wins) versus a UK-layout to secure the service endpoints, adds basic monitoring and metrics, and accesses the remote service via SSH.

Developing Big Data applications is a relatively new art and developing a comprehensive solution can be challenging. Some of the key challenges arise from bringing together complex domains such as stream analysis, batch workflow orchestration and data import and export. Several open source projects that address developing big data applications have emerged in the past few years but each project typically only address one of these domains. Furthermore, being distinct independent projects they have different configuration and extensibility models. Spring XD is a new project that aims to tackle big data complexity. It builds upon proven Spring technologies and provides a scalable runtime environment that is easily configured and assembled via a simple DSL. Come discover how easy it is to create big data applications in this introduction to Spring XD.

While some of today's systems can hit μSec performance it usually take a lot of good design and optimization. The solution is often hard-baked and inflexible and the end user still wants the flexibility promised by ESBs with dynamic routing based on runtime rules with transformations from one format to another. Josh and John will walk you through the latest in high performance message handling with Spring Integration covering non-XML (binary and CSV) data, code generation, on-the-fly compilation, dynamic routing and in-memory queries - an hour well spent.

Reactor is a succinct and powerful foundational library for building reactive, fastdata applications on the JVM. Although it is part of the Spring IO platform, the core Reactor libraries have no dependency on Spring. Above the core library, there's direct support for the Disruptor via the high-speed Processor abstraction which provides a Reactor API over the RingBuffer, first-class support for the high-performance JavaChronicle persistent message-passing library through the flexible PersistentQueue abstraction, first-class support for Groovy closures and @CompileStatic…

Readers of Josh Bloch's "Effective Java" are sometimes perplexed when they reach Item #15: "Minimize Mutability." If we are to minimize mutability, then obviously we must maximize immutability. While all Java programmers utilize immutable objects every day (e.g. java.lang.String), when asked to create our own immutable classes, we often hesitate. However, if we push through this hesitation, we'll reap the benefits of simpler reasoning about program correctness, free thread safety, and other benefits.

One of the primary issues faced by enterprise Java programmers seeking to…

Operations teams tend to get nervous when debugging tools are installed on production systems. This is understandable as most people have had at least one debugging tool crash a system. However, are there tools that can be run in a production environment? This talk will cover methods and tools that can be used to uncover and resolve performance problems arising in Java web applications that use the Spring Framework. This talk will touch on a few common problems such as slow SQL, slow web page load times, blocked threads, and exceptions in the code. It will use a variety of diagnostic tools to examine these problems including log files, jmap, jvisualvm, and New Relic. Finally, the talk will evaluate the use of these tools in a production environment, separating them into what can and cannot be realistically used in live production web applications.
