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!

The GA release of Spring Data release train Fowler marks the finishing line of 6 month of development. It's time to give you an impression of the content of this release and a brief overview about individual features. The major themes of the Fowler release train were performance improvements and enhanced Java 8 support that are mainly reflected in the Spring Data JPA and MongoDB modules but a lot of other ones have seen significant improvements, too.

The easiest way to upgrade to the Spring Data Fowler release train is by using Spring Boot and configuring the spring-data-releasetrain.version property to Fowler-RELEASE. If you're not using Spring Boot yet, add the Spring Data BOM to your <dependencyManagement />…

Welcome to another installment of This Week in Spring! This week, I'm in São Paulo, Brazil, where I presented a workshop on building cloud-native applications - specifically microservices - with Spring Boot, Spring Cloud and Cloud Foundry (via Pivotal Web Services).

• Spring Data lead Oliver Gierke has just announced Spring Data Fowler has gone GA, packed with lots of advanced Java 8 features, as well!
• The agenda for the Spring IO show in Barcelona, Spain is now available! Check it out!
• Done with the microservices hype? Then let's get practical on April 21st. I'll be talking about how Spring Cloud integrates service registration (e.g.: Eureka, Consul, or Zookeeper), declarative REST clients (with Netflix's Feign), reactive programming and the circuit breaker pattern with Hystrix to support easy, robust service-to-service invocations.
• Marius Bogoevici and Mark Pollack are teaming up for a webinar on Tues April 28th about Reactive data-pipelines with Spring XD and Kafka…

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 Session together with Spring Cloud to combine the features of the systems we built in parts II and IV, and actually end up building 3 single page applications with quite different responsibilities. The aim is to build a Gateway (like in part IV) that is used not only for API resources but also to load the UI from a backend server. We simplify the token-wrangling bits of part II by using the Gateway to pass through the authentication to the backends. Then we extend the system to show how we can make local, granular access decisions in the backends, while still controlling identity and authentication at the Gateway. This is a very powerful model for building…

This week I'm in São Paulo, Brazil presenting at QCon SP. I had an interesting discussion with someone who loves Spring's REST stack, but wondered if there was something more efficient than plain-ol' JSON. Indeed, there is! I often get asked about Spring's support for high-speed binary based encoding of messages. Spring's long supported RPC encoding with the likes of Hessian, Burlap, etc., and Spring Framework 4.1 introduced support for Google Protocol Buffers which can be used with REST services as well.

From the Google Protocol Buffer website:

Protocol buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages...

Spring Boot STS Tutorial

Spring Tool Suite 3.6.4 was just released last week. This blog post is a tutorial demonstrating some of the new features STS provides to create and work with Spring Boot applications.

In this tutorial you'll learn how to:

• create a Simple Spring Boot Application with STS
• launch and debug your boot application from STS
• use the new STS Properties editor to edit configuration properties.
• use @ConfigurationProperties in your code to get the same editor support for your own configuration properties.

Creating a Boot App

We use the "New Spring Starter" wizard to create a…

Welcome to another installment of This Week in Spring! This week I've been busily preparin for a workshop I'll be giving at QCon São Paulo next week. If you're at the show, I hope you'll come out to say hi, ask questions and we'll talk Spring and Cloud Foundry. Obrigado!

4. I put together a post on getting started with Spring Data Couchbase
5. Spring XD ninjas Marius Bogoevici and Dr. Mark Pollack are going to be giving a webinar on April 28th that introduces using Spring XD and Apache Kafka…

This blog was inspired by a talk that Laurent Doguin, a developer advocate over at Couchbase, and I gave at Couchbase Connect last year. Merci Laurent!

This is a demo of the Spring Data Couchbase integration. From the project page, Spring Data Couchbase is:

The Spring Data Couchbase project provides integration with the Couchbase Server database. Key functional areas of Spring Data Couchbase are a POJO centric model for interacting with Couchbase Buckets and easily writing a Repository style data access layer.

What is Couchbase?

Couchbase is a distributed data-store that enjoys true horizontal scaling. I like to think of it as a mix of Redis and MongoDB: you work with documents that are accessed through their keys. There are numerous client APIs for all languages. If you're using Couchbase for your backend and using the JVM, you'll love Spring Data Couchbase…
