By now you should have heard about coupling and cohesiveness. These concepts, and their third cousin, polymorphism, is what we as developers chase day-in and day-out. They tease us with reusability and the promise of comprehensiveness of our code. They entice us with promises of code quality and testability. They came in the form of "Object Oriented' design, followed by GoF and SOLID Design Patterns, DDD, BDD.. but none of them delivered what they promised. Now, the new kids on the block are Functional Programming and Modularity Patterns.

What happens when you choose to go through large refactoring exercise on the back of Modularity Patterns, in a large, complex enterprise project? The journey was long, arduous and gruesome. On the way, I made many enemies and found some new friends. This talk will highlight the issues, both technical and otherwise, and how it was overcome; where did Spring help and where did it hurt. In the end, was it worth it? Come to this session and you will find out.

Welcome back to another installment of This Week in Spring! There is, of course, lots to talk about so let's get to it.

If you're in the bay area, I'd like to invite you to the Silicon Valley Code Camp this weekend. I'll be giving two talks - one on building RESTful Services with Spring and the other on Improving Spring Java configuration muscle-memory with the amazing Phill Webb. Pivotal will also have a booth there, and we'd love to see you!

1. Spring Data Arora SR3 has been released! The new release folds in Spring Data Commons 1.5.3, Spring Data JPA 1.3.5, Spring Data MongoDB 1.2.4 and Spring Data Neo4j 2.2.3. Nicely done, as usual, Oliver!
…

The Spring Data team has just released the final service release for the Arora release train. SR3 includes the following modules:

• Spring Data Commons 1.5.3 - Changelog - JavaDoc - Artifacts
• Spring Data JPA 1.3.5 - Changelog - JavaDoc - Artifacts
• Spring Data MongoDB 1.2.4 - Changelog - JavaDoc - Artifacts
• Spring Data Neo4j 2.2.3 - Changelog - JavaDoc - Artifacts

In it's core the release includes all bug fixes made between Babbage RC1 and GA that were candidates for back porting. It's a recommended update for all users on Arora that cannot upgrade to Babbage for whatever reason.

The third service release is the last release for Arora. The Spring Data team is now focussing on the development of the first milestone for the upcoming release train called Codd as well as service releases for Babbage. You can find an overview of the further release planning…

"Agile Software Development" is an ambiguous term. It's an umbrella term. It's a controversial term. But what does it really mean? The first principle of agile development is to keep feedback loops small to allow a team to make frequent, small corrections on the way to delivery. Pivotal Labs practices this every day. We coach our clients on how to re-view their problems and approach from first principles. We wrote Pivotal Tracker - the Agile project management app - to work the way we think. Come learn about tight feedback loops, how to use them in software, and how Pivotal Tracker can keep your backlog sane.

Hello everyone! Pieter posting this on Josh Long's behalf here... this week the Spring and Cloud Foundry teams are at JavaOne talking to developers about Spring, Cloud Foundry, Hadoop and big data! Happily, our pretty new @GoPivotal booth has garnered a lot of attention!

I met Duke, too! I think the big guy was as happy to see me as I was him!

1. Spring ninja Greg Turnquist put together a nice post on how to contribute to Spring Boot with a pull request. The article does ultimately talk about the processing sending a pull request, but most of it's a really great introduction to extending Spring Boot to suit a new use case (like JMS, which simply hadn't been added yet). This post also introduces some cool features in Spring Boot, if you haven't learned about it yet.
2. Speaking of Spring Boot, check out this upcoming Spring Boot webinar featuring project co-lead Phil Webb!
3. Rossen Stoyanchev put together a knock-out piece how to build web applications that use websockets, or Sock.js, and how to then layer STOMP on top of that for an easier messaging-style interaction between the browser and the service.
4. Rossen also has an upcoming webinar on Oct 8th, Building WebSocket Browser Applications with Spring, showing off the best of his SpringOne2GX 2013 session.
5. I encourage you to check out the upcoming webinar featuring James Williams on building big data applications with Spring, Spring XD and Hadoop! This is going to be an awesome talk. James has some killer examples and knows his stuff.
6. In related news, I put together a quick post on my thoughts on Data Integration, Stream Processing and Spring XD.
7. Jakub Kubrynski has put together a nice post on how to use load-time weaving to inject dependencies into objects not managed by the Spring container using a couple of different approaches.
8. Nitin Kumar put together a nice look at Spring Integration, a lightweight approach.
9. Tomás Lin, who says that he loves testing Grails applications with Spock, put together a great post on how to test with Spring Boot with Spock.
10. Sometimes, you need to do RMI, and when you do, Spring has you covered!
11. The BitwiseOR blog has a great post on how to use Spring Boot to build REST services, using Groovy no less! Win! I'm not sure if I agree with the conclusion, but whatever it takes for people to be able to use this to simplify development, it's a win! And, with really great posts like this, hopefully it won't be long at all before everyone's bootstrapping their development, too!

At Pivotal we are bringing two open source projects together -- Hadoop and the very rapid and widely used Spring java application development framework to help build Big Data Applications. While Hadoop is proving to be the defacto foundation for storing and processing data, real-world scenarios require much more. Millions of developers are already using Spring to create high performing, easily testable, reusable code without any lock-in. In this month's webinar James Williams will explore how Spring XD (Xtreme Data) is addressing Big Data Application needs including:

• High throughput distributed data ingestion into HDFS from a variety of input sources
• Real-time analytics at ingestion time, e.g. gathering metrics and counting values
• Hadoop workflow management via batch jobs
• High throughput data export, e.g. from HDFS to a RDBMS or NoSQL database.

So, you've written a "Hello world!" WebSocket application or perhaps even a chat sample. You're able to exchange messages even in pre-Servlet 3.1 containers and pre-IE 10 browsers (that don't yet support WebSocket) thanks to the SockJS protocol and Spring's support for it. However a message is a blank page that can have any content. Whatever message format you choose, proprietary or standard, both client and server need to understand it as well as distinguish different kinds of messages. You need support for the publish-subscribe pattern central to messaging applications so you can broadcast messages to one or more subscribers. You need to incorporate security, validation, and so on. In short you need to build a real-world application. If you're used to web applications (and Spring MVC annotated controllers) you are familiar with the foundation that HTTP provides including URLs (nouns), HTTP methods (verbs), headers, parameters, and others. Imagine building an application without HTTP, just a socket. WebSocket gives you this brand new, exciting capability -- full duplex, two-way communication -- yet you no longer have an application-level protocol. Can an entire application be built around a single Endpoint class processing all messages, assuming a single WebSocket connection between browser and server? Join Rossen Stoyanchev as he demonstrates that, thankfully, the WebSocket protocol has a built-in sub-protocol mechanism.

In case you missed this year's SpringOne 2GX conference, one of the hot keynote items was the announcement of Spring Boot. Dave Syer showed how to rapidly create a Spring MVC app with code that would fit inside a single tweet. In this blog entry, I will peel back the covers of Spring Boot and show you how it works by putting together a pull request.

Autoconfiguration

Spring Boot has a powerful autoconfiguration feature. When it detects certain things on the classpath, it automatically creates beans. But one feature it doesn't yet have is support for Spring JMS. I need that feature!

The first…
