Let's establish some vocabulary, before we begin. When we talk about configuration in Spring, we're usually talking about the inputs into the Spring framework's various ApplicationContext implementations that help the container understand what it is you want done. This might be an XML file to be fed into a ClassPathXmlApplicationContext, or Java classes annotated a certain way to be fed into an AnnotationConfigApplicationContext.

Another type of configuration, as nicely described in the 12-Factor application manifesto, is any of an application's that is likely to vary between deploys (staging…

In this article we show some nice features of Spring Security, Spring Boot and Angular JS working together to provide a pleasant and secure user experience. It should be accessible to beginners with Spring and Angular JS, but there also is plenty of detail that will be of use to experts in either. This is actually the first in a series of articles on Spring Security and Angular JS, with new features exposed in each one successively. We'll improve on the application in the second and subsequent installments…

In this article we continue our discussion of how to use Spring Security with Angular JS in a "single page application". Here we show how to use Angular JS to authenticate a user via a form and fetch a secure resource to render in the UI. This is the second in a series of articles, and you can catch up on the basic building blocks of the application or build it from scratch by reading the first article, or you can just go straight to the source code in Github. In the first article we built a simple application that used HTTP Basic authentication to protect the backend resources. In this one we add a login form, give the user some control over whether to authenticate or not, and fix the issues with the…

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.

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…
