Welcome to another installment of This Week in Spring! Can you believe we're already halfway through January? We've got a lot to cover, so let's press on! In particular, there's a lot of great video content to keep you occupied for hours this week. ... [More] Enjoy! Join Scott Andrews as he discusses the role of Javascript in an exciting webinar on January 24, 2013: Architecture of a Modern Web App. Join Brian Cavalier and John Hann as they discuss Inversion of Control (IoC) and Javascript in a Webinar on January 24, 2013: IOC + Javascript. The A thought with a cup of coffee!!! blog has an introductory post comparing Spring's ApplicationContext to the more general class, the BeanFactory. Last year in April, I spoke at the Great Indian Developer Summit in Bangalore, India. The show was amazing and - I've just been made aware - some of the videos are starting to trickle online. One talk I gave was Spring and Cloud Foundry: a Marriage Made in Heaven, which you can watch online. Unfortunately, they don't seem to also have the slides! You can get the slides from my SlideShare.net profile page. There are multiple permutations of this deck. Enjoy! We released two new SpringOne2GX session replays, Automated Provisioning of Spring Apps to EC2 & VMware vCloud, and Addressing the Big Data Challenge with a Graph: Spring Data Neo4j. Did you miss Jan Machacek's fantastic talk, Akka Eye for the Spring Guy or Gal, from SpringOne2GX 2012? This video is also available on InfoQ! The Java Code Geeks blog has a nice dissection of the way Spring MVC's RequestMappingHandlerMapping class works. Roy Clarkson and Craig Walls' talk, Extending Spring MVC with Spring Mobile and JavaScript, is also now available on InfoQ! Want to take baby steps in learning core Spring 3.0? This blog's for you! Brian's Java blog has a fairly exhaustive introduction to building a SOAP-based web service using Spring Web Services. Definitely worth a read if you need to build contract-first, document-literal SOAP webservices! Mark Reddy's written a nice blog on how to use Spring's autowiring capability in conjunction with the @Qualifier annotation. The Kruders blog has an (I confess) very introductory look at how to setup a Spring MVC project with Log4j, but, sometimes, this is exactly what you need! The Java Creed blog has a nice introduction to Spring's caching support as of 3.1. Christos Matskas has put together a nice post on how to handle multiple object definition files with Spring.NET The HMKCode blog also has a nice introductory look at core Spring. The Kani Notes blog has a nice introduction to data-access logic with Spring and JDBC. Old school but still cool! Xavier Padro's written a nice post on how to test WebFlow 2 flows with inheritance. The fpqqchao blog has a nice post on using Spring's RoutingDataSource. The post is in Chinese, however, so have your Google Translate (or equivalent) plugin's handy! Mashooq Badar has put together a nice post on building a master/worker architecture with Spring Integration. Also, due to some issues with audio/video rendering, we've released a remastered recording of a November webinar: Data Access with Spring -- Getting the most out of JPA, JDBC and REST Scott Andrews' epic talk from SpringOne2GX 2012 - Architecture of a Modern Web App - is now available online on InfoQ. Don't miss this month webinar (above) for an updated talk. Ben Hale gave a very well received talk on RESTful API design with Spring MVC at SpringOne2GX, which you can also find online at InfoQ.   [Less]

Automated Provisioning of Spring Apps to EC2 & VMware vCloud This session will focus on deploying and managing your Spring Application in the cloud using VMware vFabric Application Director. A series of Spring applications, increasing in ... [More] complexity, will be deployed. The deployments will cover generating property files and activating Spring profiles. Some other highlights of the presentation will be deploying to VMWare vCloud & EC2, updating an existing deployment, and some general tips & tricks. The session will begin by using a simple contact application to be deployed as a standalone webapp with an in memory DB on single node, then it will continue with a more advanced example using PostgreSQL DB on a separate node, and finally demonstrate the use and configuration of an external DB & an Apache proxy. The session will conclude with the deployment and discussion of Nanotrader, a sample trading application, with complex requirements. About Brian Dussault Brian Dussault is a Staff Engineer with the vFabric division of VMware and has 14+ years of experience in software engineering.

More About David »   Addressing the Big Data Challenge with a Graph Graphs are everywhere. From websites adding social capabilities to Telcos providing personalized customer services, to innovative bioinformatics research, organizations are adopting graph databases as the best way to model and query connected data. If you can whiteboard, you can model your domain in a graph database. In this session Emil Eifrem provides a close look at the graph model and offers best use cases for effective, cost-efficient data storage and accessibility. Take Aways: Understand the model of a graph database and how it compares to document and relational databases Understand why graph databases are best suited for the storage, mapping and querying of connected data Emil's presentation will be followed by a Hands-on Guide to Spring Data Neo4j. Spring Data Neo4j provides straightforward object persistence into the Neo4j graph database. Conceived by Rod Johnson and Neo Technology CEO Emil Eifrem, it is the founding project of the Spring Data effort. The library leverages a tight integration with the Spring Framework and the Spring Data infrastructure. Besides the easy to use object graph mapping it offers the powerful graph manipulation and query capabilities of Neo4j with a convenient API. The talk introduces the different aspects of Spring Data Neo4j and shows applications in several example domains. During the session we walk through the creation of a engaging sample application that starts with the setup and annotating the domain objects. We see the usage of Neo4jTemplate and the powerful repository abstraction. After deploying the application to a cloud PaaS we execute some interesting query use-cases on the collected data. About Emil Eifrem Emil Eifrem is CEO of Neo Technology and co-founder of the Neo4j project. Before founding Neo, he was the CTO of Windh AB, where he headed the development of highly complex information architectures for Enterprise Content Management Systems. Committed to sustainable open source, he guides Neo along a balanced path between free availability and commercial reliability. Emil is a frequent conference speaker and author on NOSQL databases.

Welcome back to another installment of This Week in Spring. As usual, we've got a lot to look at, so, without further ado... GigaOM has a nice roundup of some of the exciting and important tools in the big-data ecosystem right now. ... [More] There are many different tools serving different segments of the use cases, and of course Spring Data is mentioned in there, too! The ODBMS Industry Watch blog and professor Roberto V. Zicari has a nice interview with Spring ninja David Turanski on Spring Data. Definitely a good read! Robin Varghese has put together a straight-forward blog on sending email with dynamic templates driven by Velocity. This seems to be a common use case, and it's always good to find more up-to-date resources. Many people will no doubt have found Matt Raible's post from 9 years ago on the same subject, which is also very illustrative but, alas, a little outdated. Nice to see this more updated approach to an old classic! Hey, this is interesting! Did you guys know there was a Spring for Delphi (also, I guess, referred to as Spring4D)? Me either... @_@ With that in mind, I found this post introducing some of the collection libraries that seem both very friendly and powerful in Spring for Delphi. Cool! Eren Avşaroğulları has a nice post showing how to use dynamic languages (in particular, Groovy) with Spring. Dinesh Rajput has put together a blog introducing some of the features unique to the Spring Batch 2.x generation, which - while Spring Batch 2.x has been out for years - is always worth a look! The Java all and Sundry blog has a nice writeup on a piece of Spring MVC's machinery, the RequestMappingHandlerAdapter. Alex Soto's back, this time with a post on unit testing Spring Data MongoDB with NoSQL Unit! Cool. The Java Success blog has a post introducing some of the landscape for enterprise integration solutions in the JVM community, and demonstrating some of the concepts of enterprise integration, specifically, with Spring Integration. The Develop and Conquer blog has a nice example with some trickery to inject a java.util.Date value using the Spring Expression language and the @Value annotation. Very cool! Abhijit Ghosh put together a decent SpringMVC-based HelloWorld application using Tomcat, Maven, Eclipse (m2e). [Less]

I almost typed 2012 when I composed this post! It's already 2013! I hope your holidays were wonderful. Welcome back to another installment of This Week in Spring! It's time to begin another exciting new year (and to remember to use the ... [More] correct new year in text!). With that, let's have a look at the new and exciting content from all around the community. The epic book by Spring Security lead Rob Winch and Peter Mularien on Spring Security 3.1 by Packt publishing is now out! The book is a great resource for people who are looking at Spring Security and want the scoop from the source. Are you using Spring Security to handle login and logout in your application? Sometimes it's necessary to tailor the behavior of how login and logout are accomplished. Perhaps you need to tear down some state or do logging. In any event, this post demonstrates the configuration and base contract of a logout handler. Chris Shayan has a nice post that illustrates how Spring Batch can help make short work of complex enterprise-y batch processing, complete with code and examples! Nice job! Spring Data Redis example The Java Kart blog has a nice post that introduces Spring Data Redis with the JRedis client library Desam Venu Madhava Reddy has a very simple post identifying some of the main reasons why people use Spring. There are many reasons people come to Spring, and these are some of the very high level ones. The Cafe Techno has a nice post on the complete setup of a SimpleFormController in Spring MVC. The example uses Spring MVC and explicitly wires up the machinery for working with Spring MVC. You don't need to do much of this in Spring 2.5 (introduced in 2007) and later, instead relying on the defaults and conventions. That said, if you want to override the framework, then understanding some of these things are wired together can be very helpful. / The Developer's Diary blog has a nice post on autowiring a map, list, or array using Spring annotations This blog is in Chinese, and has a simple example of how to setup a Spring MVC 3.2 example. NB: I'd recommend using the Java-centric configuration for this, as this is needlessly XML-centric. In a Spring 3.1+ and Servlet 3 environment, there's no need for XML (for Spring MVC or web.xml). The all and sundry blog has a nice post on Spring Data JPA and pagination This post is in Japanese, and from what I can gather it's aimed at showing how to build a lean Spring application using MyBatis, Freemarker, etc. This post is also in Chinese, and shows the various kinds of dependency checking in Spring. http://manikmagar.wordpress.com/2013/01/01/spring-mybatis-integration-and-junit-testing-using-springs-embedded-database/ I had some time over the holiday and decided to quickly scratch one item off of my 2012 new years resolutions (I got it done before new years, and besides, better late than never!): I migrated my photos away from my Flickr account to another service which was cheaper and more invested in. To do this, I used the community-supported Spring Social Flickr project. The project is, decidedly, not yet finished, but works well enough. I forked it and added a Spring Batch downloader which reliably downloads all the photos into albums named for the ID of the https://github.com/joshlong/spring-social-flickr The Fish blog (also in Chinese) has a nice post on using the Danga memcached client from Spring. Simon Massey has a nice post on server-side pagination with ZK (a widget-centric web framework), Spring Data MongoDB and Google Maps. Do I need to say anymore? Check it out! The Dinesh on Java blog has a nice, introductory post on using Spring MVC interceptors. Good stuff! [Less]

Welcome back to another, very special holiday, and end-of-year installment of This Week in Spring! If you've been a follower of this roundup, then you know that 2012's been a very exciting year for Spring! Let's look at some of the highlights ... [More] , first, before we get to our weekly roundup: Springing Forward Of course, this year saw the release of Spring 3.2, released a year exactly from the release of Spring 3.1, packed with new features and helping Spring retain its position as the premiere platform for building web applications. This year also saw many major improvements and iterations in the other Spring projects like Spring Integration 2.2.0 GA, Spring Data The Cloud Spring works very well on all cloud platforms, owing to the natural decoupling from the underlying platform that dependency injection provides, but it has always - and continues - to enjoy a special place in the sun on Cloud Foundry, the open source PaaS. And, what a year it's been for Cloud Foundry! We've seen ecosystem partners like App Fog take the Cloud Foundry bits and run with them. We've seen the support for Spring applications on Cloud Foundry improve considerably with new features like standalone processes, and much more. The RESTful Web If you ask me, the most exciting part of this year was watching Spring's web support improve. If you're looking to build a web application (including in a Servlet 3 environment) or expose RESTful API endpoints, Spring MVC is the natural choice. If you want secure those RESTful endpoints, Spring Security OAuth is an easy to use binding that supports OAuth on top of REST. Need to connect to social service providers like Twitter, Facebook, LinkedIn and GitHub via OAuth? Use Spring Social. Want to support the principles of HATEOAS in your RESTful endpoints? Check out Spring HATEOAS. Do you want to transparently and easily expose Spring Data repositories for use as RESTful endpoints? You need look no further than Spring Data REST. There are no richer, more comprehensive or more integrated set of solutions for building rich, RESTful web applications than those that Spring provides today. Git'ing Involved This year, in particular, saw community interaction in the Spring open source projects skyrocket, now that all of the projects are all fully on GitHub.com/SpringSource. Spring and the other projects have always been open source, but the collaboration model that Git enables has made it very easy for projects like Spring Social, Spring Integration, and Spring Data to thrive on community input and contributions. Extending the reach of SpringSource's content We've been working hard to bring great content on all things SpringSource to all the developers, and have expanded a lot this year. For instance, besides publishing content here on SpringSource.org, did you know that you can find SpringSource on @SpringSource on Twitter, +SpringFramework on Google+, on the YouTube SpringSourceDev channel and (this is particularly useful for the many fans in China) on SpringFramework on SINA Weibo? Additionally, if you like this roundup, be sure to bookmark the This Week in Spring aggregate page. Now then, on to this week's roundup! There's a lot to cover, and hopefully you wont want for things to read this week if you're taking time off for the holidays and have some spare time on your hands! If you've been following this roundup, then you know that we wrapped up our SpringOnes India and China events. For more details, checkout our wrapup post! The baeldung blog has another great post up on using Spring MVC and Spring Security to secure a RESTful web service. There are many ways to secure an HTTP REST web service, including HTTP Basic and the bespoke solution presented in this article. Many people are also using Spring Security OAuth, which lets you expose your RESTful web services through OAuth. Blogger Shaun Abram's put together a very nice post on how to stream data using Spring MVC back to the client Krishna Prasad's put together a nice post on using the claim check pattern with Spring Integration and GemFire Krishna's also put together a nice post on publish/subscribe with vFabric RabbitMQ and Spring Integration using Spring AMQP. Did you guys miss the webinar, The Data Renaissance: Going In-Memory with VMWare vFabric GemFire? Have no fear, it's available - along with a lot of other great content, on the SpringSource Dev Channel The quick guide to Java blog has a nice post on setting up a simple Spring Data MongoDB example. Corey Reil's put together a really nice post on building a Spring Batch Tasklet that reads data from an FTP endpoint. The solution, he rightly points out, was already possible with the Spring Integration FTP adapter, but he wanted to keep things as simple as possible, so he simply reused some of the Spring Integration adapters in writing his Tasklet. Nice job! The A Developer's Diary blog has a post with code on how to configure a java.util.Map<K,V> in XML The Learning via Code blog has a nice couple of posts on using Spring Web Services to expose a .xsd and .wsdl. Well, that sure flew by! As next Tuesday is January 1st, this will be the last installment of This Week in Spring for 2012! As always, it has been an absolute pleasure putting together this roundup for you. Speaking, I'm sure, for all of SpringSource, let me wish you the warmest of holidays and a very, very happy new year! [Less]
