This Week in Spring - February 17th, 2015

Engineering | Josh Long | February 17, 2015 | ...

Welcome to another installment of This Week in Spring! This week I've been in studio recording the next iteration of the Spring Livelessons series, this one on building cloud-native applications (microservices) with Spring Boot, Spring Cloud, and Cloud Foundry. It's been a lot of fun, and - this morning - I took a break to do two 1.5 hour webinars for O'Reilly on building Spring Boot applications and Spring Cloud microservices, both entirely live coded! It's been a fun week for me, and I hope it has for you, as well.

This Thursday the 19th marks the culmination of this year's Lunar New Year, or Chinese new year or Spring festival. What's this to do with Spring (the technology)? Not much, besides being a celebration of better things to come and a great name! So happy new year…

Java Doesn’t Suck - Rockin' the JVM

Engineering | Brian Dussault | February 11, 2015 | ...

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…

Better application events in Spring Framework 4.2

Engineering | Stéphane Nicoll | February 11, 2015 | ...

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.

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.

Introducing JHipster

Engineering | Josh Long | February 10, 2015 | ...

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


the JHipster

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…

This Week in Spring - February 10th, 2015

Engineering | Josh Long | February 10, 2015 | ...

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

SpringOne2GX 2014 Replay: Building a Continuous Delivery Pipeline with Gradle and Jenkins

Engineering | Pieter Humphrey | February 10, 2015 | ...

Recorded at SpringOne2GX 2014.

Speaker: Peter Niederwieser

G&G Special Topics

Slides: http://www.slideshare.net/SpringCentral/continuous-delivery-with-gradle-and-jenkins

Getting software from a developer's machine to a production environment without a fully automated process is time-consuming and error-prone. Continuous Delivery enables building, testing and deploying of software through build pipelines with well-defined quality gates. In this session, we will discuss how to build such a pipeline with the help of Gradle and Jenkins. With Jenkins as the centerpiece of our build pipeline, we will model our way from build to deployment. We will start by introducing an examplary application and learn how to build it with Gradle. Step by step, we will touch on topics like automating unit, integration and functional tests, incorporating popular code quality tools, as well as packaging, publishing and deploying the deliverable.

SSO with OAuth2: Angular JS and Spring Security Part V

Engineering | Dave Syer | February 03, 2015 | ...

Note: the source code and test for this blog continue to evolve, but the changes to the text are not being maintained here. Please see the tutorial version for the most up to date content.

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 Spring Security OAuth together with Spring Cloud to extend our API Gateway to do Single Sign On and OAuth2 token authentication to backend resources. This is the fifth 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 last article we built a small distributed application that used
