Nighthacking at Devoxx 2013: Interview with Josh Long on Spring Boot

News | Chloe Jackson | November 20, 2013 | ...

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.

This Week in Spring - November 19th, 2013

Engineering | Josh Long | November 19, 2013 | ...

Welcome to another edition of This Week in Spring! As usual, we've got a lot to cover, so let's get to it!

I want to encourage everyone to join me on the 21st (this Thursday!) for my webinar, Have You Seen Spring Lately?. If you haven't been paying very deep attention to everything that's happening in the wide world of Spring since we became part of the Pivotal adventure, this is the one to watch! And even if you have, I'll bet you'll learn about something new and exciting, anyway. :) C'ya there!

  1. We published an article - Have You Seen Spring Lately? - to accompany the webinar today on the Pivotal blog.
  2. Mark Baars has just announced that we've just added Big Data with Hadoop and Pivotal HD to our training. Awesome!
  3. Spring Data ninja Thomas Risberg has just announced that the 1.0.2.GA release of Spring for Apache Hadoop is now available!
  4. Spring XD ninja Gunnar Hillert has just announced that Spring XD 1.0.0.M4 has just been released. The new release is packed with a lot of new things, so definitely check this release out!
  5. Spring Data lead Oliver Gierke and Spring Data Couchbase lead Michael Nitschinger have just announced the availability of milestone two for the Spring Data Couchbase module! Michael also followed up with an initial, but promising, pull request for Spring Boot support for Spring Data Couchbase, too! :)
  6. Excited about the recent Reactor 1.0 release and want to learn more? Check out the upcoming webinar featuring Reactor lead Jon Brisbin on December 3, 2013! I'll be there, eagerly listening, and I hope to see you there, too.
  7. Spring and Cloud Foundry ninja Matt Stine's doing a webinar on December 10th called Spring with Immutability that will introduce how Spring can help with item #15 in Josh Bloch's canonincal Effective Java book: minimize mutability.
  8. The replay for the SpringOne2GX2013 session from New Relic: Troubleshooting Live Java Web Applications is now available online.
  9. Spring Data GemFire 1.3.3 has been released!. Don't quite have a release note for it, yet, though.
  10. Check out this demo of Pivotal CF - the turnkey Cloud Foundry in a box for on-premises deployment - in action.
  11. Using Redis? We love Redis! We found this great post from a few years ago with various uses cases readily solved with Redis. Enjoy!
  12. Pinterest just launched their first web API. There's nothing Spring-related about this mention, yet, but I'm just throwing this out there because I'm taking bets on how soon we'll see someone in the community create a Spring Social Pinterest binding! :)
  13. Friendly reminder: you can get a lot of cool Spring / Pivotal stuff from Homebrew to flesh out your Java stack:

    $ brew tap pivotal/tap; $ brew install springboot springxd rest-shell maven groovy redis rabbitmq tomcat

  14. I really enjoyed this sort of look behind the curtain with Spring team engineer Greg Turnquist.
  15. The Spring Exchange, put on by our friends at Skills Matter, took place in in London recently. There were many great talks, and most (all?) of it has been recorded and put online! Enjoy!

Processing Big Data with Hadoop and Pivotal HD

Engineering | Mark Baars | November 19, 2013 | ...

For 2014 Pivotal is launching a new training around Apache Hadoop and Pivotal HD. Pivotal HD Enterprise offers the capabilities of Apache Hadoop in a fully supported, enterprise-ready distribution. This new comprehensive training will provide competent Java Developers with the skills necessary to exploit the extended Capabilities of Pivotal HD, “The world’s most powerful Apache Hadoop distribution”. The training commences with a grounding in the relevant core technologies:

  • Big/Fast data, NoSQL, and their role in modern Business applications
  • Background on Hadoop and the significance of the Pivotal HD distribution
  • Introduction to GemFire and SQLFire, distributed cache technologies

Spring Data Couchbase 1.0 M2 released

Releases | Oliver Drotbohm | November 18, 2013 | ...

On behalf of module lead Michael Nitschinger, I am pleased to announce the availability of milestone two of the Spring Data module for Couchbase.

This new release brings both feature enhancements and bugfixes, taking the library full steam to a release candidate soon. Highlights of this release are custom @View annotations on repository finder methods and better marshaling support for dates, enums and class types. Also, the underlying Couchbase Java Client has been updated to the latest 1.2.2 versions, bringing better rebalance stability and performance improvements. This M2 release is available from the Spring IO milestone repository

SpringOne2GX 2013 Replay: Troubleshooting Live Java Web Applications

News | Chloe Jackson | November 13, 2013 | ...

Recorded at SpringOne2GX 2013 in Santa Clara, CA.

Speaker: Ashley Puls, NewRelic

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.

Webinar: Spring with Immutability

News | Chloe Jackson | November 13, 2013 | ...

Speakers: Matt Stine

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…

Webinar: Reactor

News | Chloe Jackson | November 13, 2013 | ...

Speaker: Jon Brisbin

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…
