Building Your Java Configuration Muscle Memory

Using a module that provides a Spring XML namespace and integration API is muscle memory for most people: add the .xsd to the imported XML schemas for the configuration file, maybe enable a annotation-driven variant if it's available, autocomplete some XML stanzas, and then you're set! But what about Java configuration? Java configuration has been around in some form since at least 2005. It was merged into the core framework in 2009 and since then we've seen a slew of new Java configuration-powered DSLs pop up. 2013, in particular, has seen alpha-or-better cuts of Java configuration support for Spring MVC, Spring Security (and Spring Security OAuth), Spring Batch, Spring Social, Spring Data (including all the modules under it: REST, MongoDB, JPA, Neo4j, Redis, etc), Spring HATEOAS, and more all provide milestone-or-better cuts of a Java configuration integration. Tomcat 7 (and all Servlet 3-compatible containers) offer a programmatic alternative to web.xml. This provides another great integration hook for modules that wish to integrate with the web container, removing the configuration burden from the user. There's a lot of power here and it's easy to get started if you know what to look for. In this talk, join Spring Developer Advocate Josh Long and Spring-core commmitter, all-around nice guy, and Spring Boot ninja Phil Webb as they introduce the Java configuration support in the various Spring projects, show how to approach them when integrating them into your code, and - if the situation demands - how to write your own Java configuration DSL.

Spring RESTBucks - A hypermedia-driven REST webservice

Spring MVC forms a solid foundation to implement REST based web-services in Java. However, in real-world projects developers still face challenges when it comes to advanced questions of REST. How to really leverage hypermedia? How to model more complex business functionality with REST. The talk introduces the Spring RESTBucks sample implementation of a hypermedia-driven REST web service and explains how it is using hypermedia elements to implement business processes and how Spring technologies (Spring Data REST, Spring Data JPA and Spring HATEOAS) help developers building the system.

REST-Ful API Design

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.

Spring with Immutability

One of the primary issues faced by enterprise Java programmers seeking to utilize immutable classes are framework issues. Enterprise frameworks from Spring to Hibernate have varying levels of support for immutability, ranging from decent to nonexistent. However, there several practical solutions available to the Spring developer, and this session will illuminate what's available.

Spring - Reactor

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, high-performance TCP client and server support based on Netty 4.0, powerful annotation-based Spring support, and much more. Join Jon Brisbin at the event to get introduced to the first major GA release of Reactor, and learn how Reactor's Promise and Stream APIs are used to wrangle the inherent complexity of asynchronous, event-driven application code.

Data Modelling and Identity Management with OAuth2

The OAuth2 specification (wisely) leaves a lot of areas open to interpretation and implementation details, so there are a lot of opportunities to impose interpretations on the flows and the underlying data. This presentation starts with a basic guide to the main features of OAuth2 and then goes on to show, with examples, how they can be exploited to support business and application use cases. For instance, should you encode access decision data directly in the access token, or make the token completely opaque? Should you be signing requests? What naming convention should you use for OAuth2 scopes? How do you go about registering users and clients? There are some obvious patterns in existing OAuth2 implementations, and Spring Security OAuth provides plenty of hooks and extension points should you wish to copy one of those, or make your own rules.

Examples will use Spring and Spring Security to show how to take advantage of the inherent flexibility, both in the spec and in the libraries.
