Whether you’re at home, office, or in-transit, connectivity is the norm. It’s a part of daily life that we’ve all come to expect and depend on. Connectivity between people and information is all about the movement and analysis of data: data delivers insights, and these insights must increasingly deliver immediate results to users. This level of always-on, always-available connectedness presents numerous challenges. The type of data, formats, and volume is dynamic, as are the data-producing agents.

Spring XD addresses these numerous challenges within a unified platform. Whether through…

Recently James Ward wrote a great blog post, “Java Doesn’t Suck – You’re Just Using it Wrong”, which highlighted numerous challenges that enterprise Java developers face in their daily routines building Java applications. The good news is that breaking out of the development rut is much easier than you may think. Over the last few years, Spring has redefined how modern Java applications are built while dramatically improving development velocity. In this post, I’ll use James Ward’s blog post as a backdrop to explain how Spring helps developers rock the JVM (using Java) while tackling each of…

Application events are available since the very beginning of the Spring framework as a mean for loosely coupled components to exchange information. One of the most well known usage of application events is the following:

@Component
public class MyListener 
        implements ApplicationListener<ContextRefreshedEvent> {
  
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ...
    }
}

This allows MyListener to be notified when the context has refreshed and one can use that to run arbitrary code when the application context has fully started.

In Spring Framework…

More Groovy Track

Slides: http://www.slideshare.net/SpringCentral/traits-design

Groovy 2.3 introduces the concept of traits in the language. Traits look like interfaces, but allow the developer to add both implementation and state into it. It introduces multiple inheritance in the language while avoiding the diamond problem. Traits will let you rethink the way you design APIs in Groovy, by favoriting composition of behaviors.

Ratpack is an asynchronous web framework for the JVM that was inspired by the simplistic nature of Ruby's Sinatra framework. Written in Java, optimized for Groovy and Java 8, Ratpack sports a high throughput, simplistic interface for rapid development of rich, real-time web applications.

This post is a guest post by community member Julien Dubois (@juliendubois), a former SpringSource employee who now works for Ippon Technologies and is creator of the JHipster project. Thanks Julien! I'd like to see more of these guest posts, so - as usual - don't hesitate to ping me (@starbuxman)! -Josh

Introduction

JHipster, or "Java Hipster," is a handy application generator that will create for you a Spring Boot (that's the Java part) and AngularJS (that's the hipster part) application.

In a very short amount of time, JHipster has became very popular on Github, and it has been featured on online magazines - like InfoQ, Infoworld or SD Times - and in conferences all over the world - Paris, London, Montreal…

Welcome to another installment of This Week in Spring!

If you're in the bay area this week, I'll be speaking at the Netflix OSS meetup in Los Altos talking about Spring Cloud on Wednesday and at Pivotal San Francisco's Open-Source Hub on the amazing Spring Session project on Thursday. I hope you'll join me for either or both! It's sure to be fun!

As usual, we've got a lot to cover, so let's get to it!

1. My pal (and Spring Boot co-founder!) Phil Webb and I gave the introduction to Spring Boot lesson at SpringOne2GX 2014 - check it out! Hopefully you'll have as much fun as we did! :)
2. DZone have published two nice Developers of the Week profiles, one for the good Dr. Dave Syer and one for Spring Batch lead Michael Minella
3. Adib Saikali put together a really nice article on InfoQ introducing the ways that Java 8 and Spring 4 win.
4. Readers of this roundup will know that I love me some JHipster, and so I am super excited to have JHipster founder Julien Dubois…

An API's documentation is a vital part of making it easy to understand and easy to use. RESTful APIs are no different. In this webinar we'll look at what should be included in your RESTful API's documentation and, just as importantly, what should be omitted. To illustrate this we'll look at some real-world examples of good and bad API documentation. We'll look at some of the problems and limitations of choosing a tool like Swagger to produce your API's documentation and conclude by looking at some alternatives that are better-suited to producing documentation that your users will love.
