Spring Framework

Welcome back to another installment of This Week in Spring! Can you believe we're already further along through December than not? Time sure flies, and yes, we are staring down the end of the year already - but the holiday season usually brings ... [More] a SpringFramework release right around this time of year, so we're feeling festive! We've even gots tons of extra SpringSource buttons to celebrate. First and foremost, Spring 3.2 has gone GA! Just read the post. Waay too much awesome in one release, and - if you've been following this series over the year than you know I've been looking forward to it. Come back and read the rest when you've upgraded your application and played with some of the awesome new stuff! I'll wait... You know what the best part is? Usually, after a new Spring release, the release train of other Spring projects is quick to adopt - so expect lots of releases in the new year! Next up, Spring Security lead and ninja Rob Winch just announced Spring Security 3.2.0.M1, packed with new features for Servlet 3 environments, among other things. We could just stop right there, you know? BUT, there's more! In this blog post, Rob Winch has answered some of the very common questions we tend to get regarding how Spring Security integrates in a Servlet 3 environment, and the results are amazing! Definitely worth a read. This stuff, following the new Spring MVC 3.2 servlet 3 support, is sure to make Servlet 3 environments like Apache Tomcat 7 an attractive offering for anyone doing serious enterprise work: no pain upgrades, lightweight and you get all these cool new runtime capabilities with Spring 3.2 and Spring Security. Not to be outdone, Alan Stewart announced Spring Roo 1.2.3, which includes support for Spring 3.2 and a slew of fixes and updates in this, the third maintenance release of 1.2. Are you using Spring with Google App Engine? Lots of people are! Spring's the only way to do serious enterprise Java development on Google App Engine, after all, without giving up a lot of functionality. Nonetheless, Google App Engine has some unique constraints that offer Spring developers some... challenges. This blog post shows how to address some of these issues on Google App Engine. On every other cloud, including Cloud Foundry, these "optimizations" are not required or even reasonable, so feel free to ignore them if you're not on Google App Engine. Guys, HTML 5 was just completed. From the release: "Though not yet W3C standards, these specifications are now feature complete, meaning businesses and developers have a stable target for implementation and planning." What's this mean for you guys in practice? Not much - HTML5 as we know it has been fairly stable for some time, but if you were looking for a reason to take the plunge, that should be it. And, SpringSource is ushering in the new era of HTML5 and JavaScript development with lots of interesting stuff aimed at civilizing this new frontier and increasing productivity. For a peak at some of the new bits, check out the upcoming webinars IOC + JavaScript and Architecture of a Modern Web App. The steady stream of amazing content from SpringOne2GX DC continues, this time with videos introducing WebSockets and how to Secure REST with OAuth 2. Be sure to grab a cup of coffee, sit down and enjoy these two 90 minute videos. Web Sockets is becoming an increasingly important part of the web landscape for messaging, and OAuth is already one of the most entrenched protocols on the web, providing the foundation for modern day, secured web services with REST, so both of these videos are not-to-be-missed. There is a lot of great Spring Social news this week! First, Craig Walls announced Spring Social Yammer 1.0.0 on behalf of Morten Andersen-Gott. Nicely done Morten! Yammer is a popular enterprise-y microblogging service, among many other wonderful things, and this integration will sure to be very useful for lots of enterprises. I've used Yammer before and it worked really well. Next, Mark Serrano blog wrote a very nice tutorial-style article on using Spring Social, Thymeleaf and Java configuration (already on Spring 3.2!). Gabriel Axel has released Spring Social Google M2, including Google Drive support. For more, see his announcement tweet. [Less]

[More] complexity that must be managed through architectural patterns. JavaScript hasn't yet embraced lessons learned from other platforms, like Java+Spring. Existing JavaScript MVC frameworks are too rigid and lack sufficient architectural plumbing. JavaScript needs flexible architectural infrastructure for building bigger, better apps. In this talk, Brian Cavalier and John Hann will introduce several concepts, including JavaScript Modules and Inversion of Control, and demonstrate how they alleviate many of the dominant problems encountered when building large JavaScript apps. Attendees will gain a firmer understanding of new architectural patterns and witness tangible examples of how these patterns improve testability, refactorability, composability, division of work, and team scalability.

[More] clients simply dumb terminals. Modern applications leverage the strengths of both the client and server to accomplish their tasks. No longer can a client side developer ignore the server, nor a server side developer ignore the client. This talk will explore the interconnected world of clients and servers, drawing inspiration from emerging frameworks that are pushing the limits of what’s possible. We will look at the history of web development to uncover trends that inform future development paradigms. The strengths and weaknesses of each paradigm will be discussed in order to help determine the best fit for a project.

Introduction to WebSockets The WebSockets technology promises to fill a niche in web applications by enabling browsers and servers to exchange messages with high frequency, low latency and low bandwith requirements in full duplex mode. The ... [More] WebSocket protocol is an IETF standard, the WebSocket API is almost standardized by the W3C, and the JSR-356 will deliver a Java API in Java EE 7. There are already implementations in node.js and in a number of Servlet containers and Java frameworks. The time is as good as ever to start digging into it and there is so much to consider — from getting familiar with the protocol and the API, to sorting through the choices on the browser and on the server side, practical challenges with browser support and network issues, and so on. Furthermore, WebSockets offer a messaging-style architecture that's in sharp contrast to the RESTful architectures that connect the web today, so learning where to draw the line will be essential. Come to this presentation for a thorough introduction to WebSockets and some practical advice on using it in your applications.

More About Rossen »        Securing REST-ful Services with OAuth2 One of the questions we get asked the most by developers and architects is: when and why would I use OAuth2? The answer, as often with such questions, is “it depends”, but there are some features of OAuth2 that make it compelling in some situations, especially in systems composed of many lightweight web services, which becoming a very common architectural pattern. This presentation will not go into a lot of detail about the OAuth2 protocol and related specifications, but will attempt to show some of the key features of a system secured with OAuth2 and the decision points when choosing to build such a system.

Welcome to another installment of This Week in Spring! We finished SpringOne China over the weekend and are today at the first of two events for SpringOne India in Bangalore and SpringOne in Hyderabad. The shows have been really amazing! In ... [More] particular, we've enjoyed the food, the sites and the amazing community that have turned up in droves! An attendee took a shot of me as I was giving a talk on Spring on Cloud Foundry Dr. Mark Pollack, myself, Gary Russell and Chris Richardson at a restaurant in Beijing I gave a talk in Bangalore and people deluged the stage with questions and greetings. I asked the last wave of people to take a photo with me. LtoR: Gary Russel, Josh Long, Jennifer Hickey, Jeremy Grelle, Oliver Gierke, Chris Richardson -- the whole SpringOne India lineup   Roy Clarkson has announced Spring for Android 1.0, which adds support for Jackson 2.x in RestTemplate through the new MappingJackson2HttpMessageConverter. It also addresses several bugs and compatibility issues with RestTemplate and Android Jelly Bean. The TomcatExpert.com portal has a nice post on Spring Insight Developer to analyze code, install it with Tomcat, and extend it with plugins. Spring Scala lead Arjen Poutsma has a nice post introducing Spring Scala. The folks over at Trifork have a great blog on properly testing Spring MVC controllers I'm going to be honest here -- I don't know, exactly, what this post is about, as it's written in Korean and the Google translation's not particularly helpful. It seems like the author's discovered a caveat related to Spring MVC's @SessionAttribute and provided a work around. Hopefully, it's useful to you if you read Korean! Are you using RabbitMQ from a .NET environment? Check out this post on EasyNewQ which is a .NET client for RabbitMQ. The GoSmarter blog has an interesting post on how to setup a fake FTP server to unit test Spring Integration FTP flows. The blog also has a nice post on mocking SFTP support in Spring Integration. The GoSmarter blog also has a nice post on using Spring Security and container-managed security Also from the GoSmarter blog, a nice post on doing test-driven development with Spring Webflow. The MonoCaffe blog has a nice post on using a Spring MVC JSP tag to allow pre-pending and appending of icons to Bootstrap's input fields. The Zen Java blog has a nice post on using creating a RESTful Spring MVC service that is consumed from Java FX. This is really slick. The Cafe Techno blog has a nice post that compares Spring MVC and Struts. Spring MVC fares very well, I'd say! The a Quick Guide to Java blog has a good post on Spring MVC internationalization.
