Building an Enterprise Application Stack means the necessity to have a service tier that can scale to the demands of business. This talk will discuss the approach to developing a scalable enterprise architecture, and will demonstrate implementations based on the variety of technologies available from the Groovy ecosystem, including Grails, Spring, Spring Boot, and Spring Integration.

Groovy has a very easy learning curve for Java developers, so many people become Groovy users without realizing all it can do. This presentation will examine features of Groovy that can make your life easier once you're past the initial adoption stage. Prerequisite: Some Groovy knowledge

Welcome to another installment of This Week in Spring! As usual, we've got a lot to cover so let's get to it!

• Spring Security lead Rob Winch just announced the amazing Spring Security 4.0 release! This one is packed with amazing features including websocket support, Spring Data integration, enhanced testing support, and much improved defaults
• The Cloud Foundry Java buildpack now supports overriding inbuilt configuration through the use of well-named environment variables! This means you can tweak all manner of the default behavior without needing to fork the buildpack!
• Good news! Spring XD 1.1.1 is released! It includes improved performance and offset management when using Kafka message bus, support for Spark's streaming reliable receiver, Kryo serialization improvements, RabbitMQ auto-cleanup options and a Sqoop…

GORM is a super powerful ORM tool that makes ORM simple by leveraging the flexibility and expressiveness of a dynamic language like Groovy. With GORM developers get access to all of the power and flexibility of an ORM tool like Hibernate without any of the complexity.

Polymer is the latest web framework out of Google. Designed completely around the emerging Web Components standards, it has the lofty goal of making it easy to build apps based on these low level primitives. Along with Polymer comes a new set of Elements (buttons, dialog boxes and such) based on the ideas of "Material Design". These technologies together make it easy to build responsive, componentized "Single Page" web applications that work for browsers on PCs or mobile devices. But what about the backend, and how do we make these apps secure? In this talk Scott Deeg will take you through an introduction to Polmyer and its related technologies, and then through the build out of a full blown cloud based app with a secure, RESTful backend based on Spring REST, Spring Cloud, and Spring Security and using Thymeleaf for backend rendering jobs. At the end he will show the principles applied in a tool he's currently building. The talk will be mainly code walk through and demo, and assumes familiarity with Java/Spring and JavaScript.

JHipster focuses on generating a high quality application with a Java back-end using an extensive set of Spring technologies; Spring Boot, Spring Security, Spring Data, Spring MVC (providing a framework for websockets, REST and MVC), etc. an Angular.js front-end and a suite of pre-configured development tools like Yeoman, Maven, Gradle, Grunt, Gulp.js and Bower. JHipster creates a fully configured Spring Boot application with a set of pre-defined screens for user management, monitoring, and logging. The generated Spring Boot application is specifically tailored to make working with Angular.js a smoother experience. Join Julien for a quick-live coding session to build a simple application, and deploy it to Cloud Foundry.

Dear Spring community,

The DISID Spring Roo team is busily working towards the 2.0 release. With Spring Roo 2.0 we would like recover the essence that defines the Roo project:

• Be a rapid application development tool, Roo isn't either a framework nor Maven plugins.
• Intelligent code generation to provide improved productivity.
  • Developers often are forced to spend too much of their time doing things that add too little value, Spring Roo's code generation helps them stay focused.
• Create applications based on the extensive set of Spring technologies: Spring Boot, Spring Data, Spring MVC, Spring Security, etc.
• Generate applications based on best architecture practices like: Service Layer, Repository Layer
• New scaffolding model that generates a fully functional responsive UI based on jQuery and Bootstrap.
• Improve extensibility and increase the collaboration of the Spring Roo project:
  • We will create the “Roo Marketplace”: the alternative to Roobot, easier to maintain and available for everyone, a place to find and keep track on third party addons and Roo Addon Suites.
  • A “Roo Addon Suite” is a great way to package and distribute a set of add-ons together, for example if you want to distribute Roo custom distributions. Roo Addon Suite is based on OSGi R5 Subsystems that provides a really convenient deployment model, without compromising the modularity of Roo.

The new Roo 2.0 is a beginning, in future versions we would like to design a new way to define the view layer components to get a true independence from view layer technologies letting the developers to try the technology that better adjust to their requirements: JSP, Thymeleaf, etc. without losing any benefit.

We have scheduled the work of the relase 2.0 in 3 main milestones:

Milestone 1: Create a smaller and easier to maintain Spring Roo distribution. From 2.0, Roo will contain the runtime and the main addons only, so new versions could be released more frequently and being kept up to date with latest Spring projects:

• Make a better separation between the Spring Roo runtime and the core addons. The Roo runtime APIs (classpath, metadata, support, etc.) must be kept as stable and backwards compatible as possible.
• Move the addons not classified as ”core addon” (GWT, JSF, ...) to their own projects to be maintained by Roo community. If your organization would like to contribute to Roo project by maintaining these addons please contact to: springroo@ disid.com
• Migrate current user guide from docbook to ASCIIdoc.

Milestone 2: Update code generation to use latest Spring technologies

• Update code generation to use the latest Spring framework versions (4.x)
  • Move from Spring framework dependencies to Spring IO Platform
• User Managed POM (ROO-3465, ROO-3478)
• Spring Profiles support
• Annotation based configuration:
  • Move to class configuration in spite of XML configuration
  • Improve application maintanability by using Spring Boot annotations
• Remove Active Record data model in favor of the Repository (Spring Data) based one.
• Generate application arquitecture based on service layer pattern by default

Milestone 3: Move web layer to HTML5

• Responsive UI – View layer based on jQuery, Bootstrap and CSS3

Important: Roo 2.0 might contain API changes and less add-ons than previous version so this release probably won't be backward compatible with 1.3. You can see a more specific roadmap in the SpringRoo JIRA:

As always, you’ll also find Roo on Twitter - either follow @SpringRoo or just include #SpringRoo in your tweets. Stay tuned to Spring Roo news!

Dear Spring community,

We are pleased to announce that the Spring Integration Kafka Support 1.1 GA is now available. Use the Release Repository with Maven or Gradle

compile "org.springframework.integration:spring-integration-kafka:1.1.1.RELEASE"

or download a distribution archive, to give it a spin.

Overview

The main reason of such a quick next point release just after 1.0 GA is to address a number of critical fixes for the upcoming Spring XD 1.1.1 and 1.2 releases. In addition, this release provides performance improvements around message generation streaming scenarios, which required an upgrade to Spring Integration 4.1, which is…
