Recorded at SpringOne2GX 2013 in Santa Clara, CA

Speaker: John T. Davies, CTO of C24

We've had powerful Rules Engines and Complex Event Processing for a good decade now and there are several powerful ones on the market, some even open source. Many of these engines though have been build around single albeit efficient applications running on a single machine. As we take Big Data head on we start to see the need to rules that we can distribute and complex events processing across our distributed system. Combining Pivotal's GemFire and C24's Integration Objects, naturally glued together with a little Spring, we can process millions of complex events in seconds. John will walk through some of the design and use-cases of these powerful system.

Speaker: Adib Saikali

Spring Framework 4.0 ships with Java 8 support that means being that you can start using all the great features of Java 8 right away. This presentation will show examples of how to use Java 8 with Spring Framework 4 in the repository layer, the services layer and the controller layer. For each example we will show a Java 7 and a Java 8 version so that you can easily see the pros and cons of the Java 8 based solution. No previous experience with Java 8 is required or assumed, we will cover some basic features of Java 8 as we go along. About the speaker: Adib is an expert programmer and has a passion for the interface between business and technology. He launched his career as a coder with a number of entrepreneurial organizations, ranging from small startups to (the then 750-employee) RIM. Adib has trained and mentored thousands of developers at organizations throughout Canada, USA and Europe. His substantial technical knowledge, extensive project experience and ability to look at technical problems from a variety of perspectives allow him to create innovative solutions to 'real world' problems.

Speaker: Glenn Renfro

With the increase in the number of devices that emit information it has become ever more important to be able to retrieve this data and process accordingly. In response to this need, MQTT has become the defacto lightweight transport for connecting an "Internet of things". With that being said, how do your applications support for eventing, messaging, and scheduling? Utilizing Spring Boot and Spring Integration you will see how to create an application with a scheduler that will retrieve data from a web service, cleanse and emit the data via MQTT. Then you'll see how to create an application, also written using Spring Boot and Spring Integration, that will capture the MQTT events and record the results. From this discussion you can see how to use these tools and take advantage of them for your own big data projects as soon as you return to the office.

Speaker: Michael Minella

Spring Batch 3.0.0 introduces JSR-352 support, among other features. Adopting a Java EE standard that was directly based on Spring Batch to begin with is fortunately, fairly straightforward for us. JavaEE7 compliance updates and expands the scope of Spring Batch 3.0.0 to combine JavaEE7/352 compliance with years of Batch's battle-tested, proven-in-production codebase. Of course, there is a wealth of capability and features that go far beyond the specification into distributed processing and beyond. In this webinar, project lead Michael Minella will cover Spring Batch's implementation of JSR-352 as well as some of the new features in the 3.0 release.

We are pleased to announce the release of the Second Milestone of the Java DSL extension for Spring Integration!

The org.springframework.integration:spring-integration-java-dsl:1.0.0.M2 artifact is available from the Spring IO Milestone Repository.

Milestone 2 includes several bug fixes, some new features and further improvements.

Thank you to all who tried milestone 1, provided feedback, raised issues, and shared their thoughts.

Here is a summary of major changes since Milestone 1:

Lambda Handler

As you may have noticed, the use of Java 8 Lambdas is the power tool to make this DSL convenient and readable. One community request we received was to allow the declaration of a Lambda for the .handle() EIP-method instead of having to declare a POJO and use it as a method invocation. But one concern was to not lose "runtime type conversion". However, you can't get the generic type for Lambdas. After some investigation we found the solution by additing a type argument. Hence, several new methods have been added to the IntegrationFlowBuilder…

Welcome to another installation of This Week in Spring. This week I'm in Toronto, Canada, visiting the Pivotal Labs offices and talking to customers doing amazing things with different parts of the Spring platform.

There is some very exciting news coming tomorrow, so be sure to check this blog tomorrow!

1. Spring for Hadoop 2.0 GA has been released! The new release adds support for Apache Hadoop (2.2, 2.4), Pivotal HD 2.0, Cloudera CDH 5, and Hortonworks HDP 2.1, supports YARN, new readers/writers for working with HDFS, new support for reading and writing POJO datasets using the Kite SDK, and a lot more.
2. Spring YARN ninja Janne Valkealahti has put together some epic guides introducing Spring YARN. Related: there are Canadian banks interested in this stuff! BANKS - the most risk averse organizations in the world!
3. Stéphane Nicoll talks about the improvements in our Spring Cache abstraction coming in Spring 4.1.
4. Stéphane also debuts the new Getting Started guide that introduces the Spring Cache abstraction. Very cool!
5. Join Greg Turnquist on July 8th for a webinar about Building your app management tools with Spring Boot. See how to monitor application logs using a little Spring Integration, Spring WebSocket+STOMP, and other technologies, all with some lightweight Boot+Groovy code.
6. From the trenches: Join Casey Doolittle and Phil Dutson on July 15th for a webinar about a crazy prioject, and how they had to Build a Shopping Cart in 24 Hours using Spring.
7. Check out this upcoming webinar by Michael Plod on why he recommends Spring - learn the business and technology case! Michael is a great speaker and frequently appears at conferences. Register now for the event on July 22nd.
8. On July 29th, Russ Danner from Crafter software will tell us about Conquering Content-enabled Web and Mobile Applications with Spring and Groovy.
9. SpringOne2GX 2013 replay from Splunk: Integrating Splunk into your Spring Applications

12. Speaking of Hadoop, check out this article on GigaOm about the state of the Hadoop ecosystem, and of Pivotal's contributions
13. I liked Rafał Nowak's introduction to Spring Boot.
14. There's a nice post on Dzone by Lubos Krnac on secure-by-default vs. secure-by-exception approaches to using Spring Security. I like it! The nice thing about Spring Security is that the choice is always yours.
15. Sezin Karli put together a nice post on how to use Spring Boot's auto configuration support for Spring Social
16. I loved Netflix engineer Tomas Lin's great post on reading and validating lists of properties with Spring Boot.
17. Congrats to team Socrates on winning the Neo4j prize at HackSummit for most innovative use of a graph Database for social good. Does this have much to do with Spring? No, it's just that Neo4j's a very nice choice for many different types of data workloads. You might check out the webinar the amazing Michael Hunger and I did on the topic a little while ago!
18. An oldie but a goodie: Keyhole software's Mark Adelsberger put together a nice post on how they use Spring's RabbitMQ support, following a tutorial on the same subject.

Speaker: Damien Dallimore

How much visibility do you really have into your Spring applications? How effectively are you capturing,harnessing and correlating the logs, metrics, & messages from your Spring applications that can be used to deliver this visibility ? What tools and techniques are you providing your Spring developers with to better create and utilize this mass of machine data ? In this session I'll answer these questions and show how Splunk can be used to not only provide historical and realtime visibility into your Spring applications , but also as a platform that developers can use to become more "devops effective" & easily create custom big data integrations and standalone solutions.I'll discuss and demonstrate many of Splunk's Java apps,frameworks and SDK and also cover the Spring Integration Adaptors for Splunk.
