Welcome to another installment of This Week in Spring! It's been a busy week for all of us on the Spring team, as you're about to see! I've just finished my presentation at the epic DevNexus show and now I'm off to visit customers in Hartford and Los Angeles before making my way to the epic ConFoo conference in Montreal, Canada. If you're in the area, be sure to ping me and say hi!

We've got a lot to cover, so let's get to it!

• Reactor project lead Stephane Maldini just announced Reactor 2.5: A Second Generation Reactive Foundation for the JVM. This is a huge part of our continued efforts to better support reactive workloads with Spring.
• We've added a new language, Kotlin, to the Spring Initializr! To learn more check out this great post by Sebastien Deleuze on Developing Spring Boot applications with Kotlin
• Spring Integration and Spring AMQP lead Gary Russell's just announced Spring AMQP 1.6.0 Milestone 1 (and 1.5.4) Available
• Spring REST Docs lead Andy Wilkinson's just announced Spring REST Docs 1.1.0.M1
• last week, Spring Data Couchbase 2.0 went GA, and this week I'm pleased to share a guest post from project lead Simon Baslé introducing …

This is your one stop shop introduction to get oriented to the world of reactive programming. There are lots of such intros out there even manifestos. We hope this is the one where you don't get lost and it makes sense. Get a definition of what "reactive" means and why it matters. Learn about Reactive Streams and Reactive Extensions and the emerging ecosystem around them. Get a sense for what going reactive…

Building highly scalable, low latency applications while simultaneously preserving consistency, high availability and resiliency requires a new breed of technology. In this presentation we introduce Pivotal GemFire along with the open source offering, Apache Geode. Apache Geode is a proven, distributed, in-memory database with ACID properties that can handle large volumes of…

Finance market prediction has always been one of the hottest topics in Data Science and Machine Learning. However, the prediction algorithm is just a small piece of the puzzle. Building a data stream pipeline that is constantly combining the latest price info with high volume historical data is extremely challenging using traditional platforms, requiring a lot of…

For many years, IntelliJ IDEA has been widely used in projects employing the Spring Framework. The latest version of the IDE (14.1) now ships with dedicated Spring Boot support. In this practical presentation we're going to look at some features from IntelliJ IDEA that will help you not only get started with Spring Boot but also guide you along the way, helping with coding and configuration management for your application. As a bonus, we'll also discover…

Spring IO Platform 2.0.2.RELEASE is now available from both repo.spring.io and Maven Central.

This maintenance release upgrades the versions of a number of the projects in the Platform to pick up their latest maintenance releases:

• Spring AMQP 1.5.3.RELEASE
• Spring Boot 1.3.2.RELEASE
• Spring Integration Java DSL 1.1.2.RELEASE

The versions of several third-party dependencies have also been updated.

UPDATE: This is a summary of XSS without HTML: Client-Side Template Injection with AngularJS. Previously the citation was in the middle of the document and difficult to find. The goal of the summary is to present the exploit and a fix without all the nuances, not to claim the work as my own.

Introduction

AngularJS is a popular JavaScript framework that allows embedding expressions within double curly braces. For example, the expression 1+2={{1+2}} will render as 1+2=3.

This means that if the server echos out user input that contains double curly braces, the user can perform a XSS exploit using…

Dear Spring Community,

The Spring Integration Java DSL 1.1.2 has been released and is available now from repo.spring.io and Maven Central.

This maintenance release includes several fixes and 3rd party dependency updates.

Thank you everyone for contribution and any kind of feedback!

We don't have particular plans for version 1.2, because we are looking into the absorption of Java DSL project by the Spring Integration 5.0, where Java 8 is minimal, but feel free to ask us for more features and share any concerns which can be considered to be included in the next maintenance release.

Today we are pleased to introduce a new project in the Spring portfolio, Spring Cloud Task. Under the umbrella of the Spring Cloud grouping of projects and the sister project of Spring Cloud Stream, Spring Cloud Task aims to bring functionality required to support short lived microservices to Spring Boot based applications. With this blog post, we are releasing our first milestone of the project and are eager for your input and feedback.

The Goals of Spring Cloud Task

In most cases, the modern cloud environment is designed around the execution of processes that are not expected to end (think web applications or stream modules). If they do, it's considered a failure by the platform and they are typically restarted. While many platforms do have some method to execute a process that is expected to end (a batch job for example), the results of that execution are typically not maintained in a consumable way. Yet for mission critical applications, even though they are short lived, they still have the same non-functional requirements long lived processes have.

While this functionality is useful in a cloud environment, the same issues can arise in a traditional deployment model as well. When executing Spring Boot applications via a scheduler like cron, it can be useful to be able to monitor the results of the application after it’s completion.

A Spring Cloud Task takes the approach that a Spring Boot application can have a start and an end and still be production grade. Batch applications are just one example of where short lived processes can be helpful.

Getting Started

In this first release of Spring Cloud Task, we introduce the basics of the configuration mechanisms as well as a repository to record what happens when a task is executed. Those who are familiar with Spring Batch and its job repository should find the general paradigms of Spring Cloud Task familiar.

To get familiar with Spring Cloud Task, the easiest way is to write an application. The documentation walks you through the creation of an initial task and its execution. You can read more about that here.

Where we're going

Tasks will be a new primitive within Spring Cloud Data Flow in the coming releases allowing users to execute virtually any Spring Boot application as a short lived task. This provides the flexibility to run everything from a simple CommandLineRunner to a full batch job in dynamic way, allowing resources to be consumed on demand and returned once complete. The upcoming releases including Spring Cloud Task 1.0 GA which we plan for just before Spring Cloud Data Flow goes 1.0 GA, will be adding features to support that effort.

Tell us what you think!

Spring Cloud Task is a new and exciting project that we feel fills an under served area of enterprise development. However, we want to know what you think. Please let us know via the issues in Github Issues, StackOverflow, or directly on Twitter!
