Welcome to another installment of This Week in Spring! I hope your holiday and new year was awesome! It's the beginning of a new year (I almost typed "2014"!), and we've got a lot of great stuff coming this year! Let's see what the internet has been doing this last week in the Spring community.

• Our friend Petri Kainulainen is back, and he's completely revamped his Spring Data JPA CRUD tutorial! Check it out! We've linked to it before in this roundup, but it's always worth re-reading!
• I really like this post that looks at introducing multitenancy into an application in terms of a JHipster-based sample.
• Inforworld has an interesting post, Why 2015 will be the year of the micro service
• Our pals in Spain are putting on their Spring IO (the conference) conference again this year! It's…

Welcome to another installment of This Week in Spring! This week, as is our tradition, we'll look back at a few of the big things that made 2014 a wonderful year to be a Spring developer. And, what a year it was!

• The tail end of last year saw Spring 4 GA and this year saw the Spring 4.1 release just shy of 9 short months after 4.0! Spring 4.x boasts a dizzying array of new features! Java 8 support, Java EE 7 support, new Spring MVC views, JSR 107 support, a powerful resource pipeline and the @Conditional annotation which of course made possible...
• Spring Boot, whose first 1.0 GA was in April of this year, has seen two epic updates (1.1, and 1.2) since then. Spring Boot's taken the community by storm, spawning all sorts of activity both from our team and, more importantly, from everybody else! The competition have attempted to downplay it, or copy it. Existing Spring users have flocked to it in droves (including the likes of Netflix and Ticketmaster). If you follow this weekly roundup, though, then you need no further evidence of the community's uptake! It's been so much fun watching people blog…

On behalf of the Spring XD team, I am very pleased to announce the second milestone release of Spring XD 1.1 and the 1.0.3 maintenance release.

Download Links:

• 1.1.0.M2 RELEASE: zip, 1.0.3.RELEASE: zip

The 1.1 M2 release includes bug fixes and enhancements as well as several new features:

• Kafka based Message Bus. If Kafka is your middleware du jour, you will feel right at home.
• Batching and compression support for RabbitMQ provides significantly increased effective message rate throughput.
• Develop Processor modules using Project Reactor’s Stream API. The Stream API is based on the Reactive Streams specification that provides a standard for asynchronous stream processing with non-blocking backpressure. This allows you to use a functional programming model as the basis for processing event streams. Combined with XD’s support for Data Partitioning on the Message Bus…

Welcome to another installment of This Week in Spring! In a few short weeks we'll be in 2015! Will that be exciting? Of course. But this week's pretty exciting as well! So much good stuff this week.

• Spring Boot 1.2.0 is here! So many new features for Java EE (Servlet 3.1-baseline, JTA, JMS and JNDI support) and improved Jackson output, Actuator endpoints, CLI updates and performance. Spring Cloud is already tracking 1.2 and will be based on this soon, as well. Get the bits.

• Spring Boot 1.1.10 is now available with numerous fixes.

• Resident mad-scientist Andy Wilkinson just announced the latest cut of the Spring IO platform library. There are lots of things of note, but in particular it's added support for Spring Integration Flow 1.0, Spring Integration Java DSL 1.0, and Spring Integration Splunk 1.1 and updated revisions for several projects besides.

Welcome to another installment of This Week in Spring! This week I'm at the Rich Web Experience in Ft. Lauderdale, FL, joining my pal Matt Stine for a workshop on building microservices with Spring Boot, Spring Cloud and Cloud Foundry.

So, without further ado, let's get to it:

• Dr. Dave Syer just announced the M3 release of Spring Cloud, complete with loads of cool stuff, including a smarter Ribbon-enabled load-balancing RestTemplate, a RabbitMQ-based aggregator for Hystrix Metrics based on Turbine 2, Spring Cloud for AWS support, and much more
• Spring ninja Sebastien Deleuze just announced some of the amazing new features in Spring's Jackson support. My favorite? JSON + XML marshalling with dynamic views. Views are a logical subset of attributes from a JSON structure that may be rendered dynamically.
• Check out Spring Roo 1.3.1 and includes bug-fixes for reverse engineering and third party addon installations. Thanks, community and Disid in particular for the updates!
• Spring and Groovy & Grails Tool Suite lead Martin Lippert just announced versions 3.6.3. The new release includes updated Spring Integration visualizations, a installed-by-default Cloud Foundry plugin and more. Check it out!
• Want to learn about the Spring Integration Java configuration DSL in terms of a working, line-by-line example? Check out this post by Java configuration DSL lead Artem Bilan and if you want to see how it works on JDK 7 or earlier, check out this post.
• Spring Data lead Oliver Gierke just announced the first milestone of the next Spring Data release train, Spring Data Fowler.
• The replay from the good Dr. David Syer's SpringOne2GX 2014 talk on security for microservices is now available online.
• Additionally, check out Dr. Syer and Spencer Gibb's talk introducing Spring Cloud to the world at SpringOne2GX 2014!
• Check out the SpringOne2GX 2014 replay of Reactor project ninjas Jon Brisbin and Stephane Maldini's talk: Building Reactive applications with Reactor and the Reactive Streams standard
• Join Spring Integration project-lead Gary Russell for a not-to-be-missed webinar on January 27th that introduces the just-released Spring Integration Java configuration DSL!
• You know what they say: go grid or go home! Or something like that…​ anyway, definitely check out my pal Luke Shannon's upcoming webinar on building scalable data applications with Spring Data Gemfire
• Adao Feliz put together a nice post on using Spring Boot and Docker. It's pretty straightforward, so check it out!
• The All and Sundry blog has a nice post on how to consume linked resources using Spring's RestTemplate.
• Check out the early bits for the next-gen Cloud Foundry built from the ground up on the Go language and supports Docker as a first-class citizen. If you know how to use Vagrant, it's dead simple to get a full working Cloud Foundry cloud running on your laptop if you follow these instructions. Do try it out and let us know!

Updated on 2015/08/31 with an additional Jackson modules section

Spring Jackson support has been improved lately to be more flexible and powerful. This blog post gives you an update about the most useful Jackson related features available in Spring Framework 4.x and Spring Boot. All the code samples are coming from this spring-jackson-demo sample application, feel free to have a look at the code.

JSON Views

It can sometimes be useful to filter contextually objects serialized to the HTTP response body. In order to provide such capabilities, Spring MVC now has builtin support for Jackson’s Serialization Views (as of Spring Framework 4.2, JSON Views are supported on @MessageMapping…

Dear Spring Community!

Recently we published the Spring Integration Java DSL: Line by line tutorial, which uses Java 8 Lambdas extensively. We received some feedback that this is good introduction to the DSL, but a similar tutorial is needed for those users, who can't move to the Java 8 or aren't yet familiar with Lambdas, but wish to take advantage

So, to help those Spring Integration users who want to moved from XML configuration to Java & Annotation configuration, we provide this line-by-line tutorial to demonstrate that, even without Lambdas, we gain a lot from Spring Integration…

Dear Spring Community!

Just after the Spring Integration Java DSL 1.0 GA release announcement I want to introduce the Spring Integration Java DSL to you as a line by line tutorial based on the classic Cafe Demo integration sample. We describe here Spring Boot support, Spring Framework Java and Annotation configuration, the IntegrationFlow feature and pay tribute to Java 8 Lambda support which was an inspiration for the DSL style. Of course, it is all backed by the Spring Integration Core project.

For those, who are not interested in Java 8 yet, we provide similar tutorial without Lambdas: Spring Integration Java DSL (pre Java 8): Line by line tutorial…
