Recorded at SpringOne2GX 2013 in Santa Clara, CA.

Speaker: Julien Dubios

This talk is a live version of my blog posts on performance-tuning the Spring Petclinic application: http://blog.ippon.fr/tag/spring-petclinic/ We will talk about JVM locks, Web application performance best practices, JDBC vs JPA, and caching We will see how to use effectively tools such as JMeter, Yourkit and Intellij IDEA to quickly solve performance issues We will also explain the methodology used, so you can follow the same steps on your own applications In this session we will talk about :

• Stress tests
• Memory leaks
• Garbage Collection
• Profiling tools
• Application Server tuning
• JVM tuning
• Locks
• JDBC vs JPA
• Lazy loading
• Caching
• And much more !

Tooling for Spring's next generation

Recorded at SpringOne2GX 2013 in Santa Clara, CA

Speakers: Andy Clement and Martin Lippert

The Spring Tool Suite (STS) is constantly evolving to keep pace with developments in Spring as well as the larger world of enterprise application development. This talk focuses on Eclipse-based tooling for the latest features throughout the Spring ecosystem. With plenty of live demos, we'll show you how to get productive quickly with Spring and STS. We''ll start with reviewing areas including XML-free Spring development and then look at early support for specific Spring's next generation features. We'll also demo the Eclipse support for Java 8 (also AspectJ support for Java 8) and spend some time looking at how this enhances your Spring development experience. In addition to the pure Java-based Spring programming, we will also cover the integration of the Groovy language tooling and show you how to program Spring apps in Groovy using the Spring Tool Suite. We will then dive into the details of the tooling to demonstrate a number of hidden gems that help you improve your productivity every day, like the built-in validations and best practices, quick-fixes, auto-completions, and automated refactorings. Last, but not least, we will review some of the performance improvements made recently in Spring Tool Suite.

Welcome to another installment of This Week in Spring! It's already July, and Summer is here! Can you believe it? Time sure flies. We've got a lot to cover this week, as usual, so let's get to it.

1. Last week, we announced the Spring IO platform. I won the lottery on this one, and they let me write the blog, but this effort reflects more than a year of internal discussion, planning, hard work, cooperation and coordination between all the Spring projects. I did my level-headed best to introduce the Spring IO platform in this blog. You should read it. If it doesn't sound awesome and very, very useful, than I've simply done a poor job explaining it! :D Don't hesitate to reach out. The Spring IO platform is a radically simpler way of dealing with dependencies across all the Spring…

On behalf of the Spring Data team I am pleased to announce the availability of the first service release of the Dijkstra release train. It includes 59 fixes overall for the following modules:

• Spring Data Commons 1.8.1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data JPA 1.6.1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data MongoDB 1.5.1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Neo4j 3.1.1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Solr 1.2.1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Couchbase 1.1.1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Cassandra 1.0.1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Elasticsearch 1.0.1 - Artifacts - JavaDocs - Documentation - …

Spring Boot 1.1.3 is available now in Maven Central. This was primarily a bugfix release for Windows users needing the executable JAR features of Spring Boot, but several other issues were resolved, and there are plenty of documentation and third-party version updates too.

Thanks again to all the people who contributed (84 committers now and rising)!

We're pleased to announce the release of Spring IO 1.0!

Spring IO is first and foremost a logical description of what many of users will already know and use as a single, cohesive, harmonized platform, centered around Spring.

Big Things Come in Small (Java) Packages

The Spring IO platform includes Foundation Layer modules and Execution Layer domain-specific runtimes (DSRs). The Foundation Layer represents the core Spring modules and associated third-party dependencies that have been harmonized to ensure a smooth development experience. The DSRs provided by the Spring IO Execution Layer…

We're pleased to announce the release of Spring IO Platform 1.0.0 RELEASE, and represents some amazing engineering work. The highlights of this release are:

• A Bill-of-Materials release (a Maven BOM dependency) that level sets the versions for you.
• Spring IO represents curated and harmonized dependencies that just work together - tests cover all the Spring projects and lots of popular 3rd party open source
• One platform, many workloads - build web (HTML-, websocket-, and REST-powered web apps), mobile, integration, batch, reactive or big data applications, or just great APIs
• Radically simplified development experience with Spring Boot
• Production-ready features provided out of the box (monitoring, metrics, etc)
• …

Speaker: John T. Davies, CTO of C24

We've had powerful Rules Engines and Complex Event Processing for a good decade now and there are several powerful ones on the market, some even open source. Many of these engines though have been build around single albeit efficient applications running on a single machine. As we take Big Data head on we start to see the need to rules that we can distribute and complex events processing across our distributed system. Combining Pivotal's GemFire and C24's Integration Objects, naturally glued together with a little Spring, we can process millions of complex events in seconds. John will walk through some of the design and use-cases of these powerful system.

Welcome to another installment of This Week in Spring - this week I'm working with the amazing Vaadin team on building some ridiculously fun applications. Be ready for more on that soon! Also, the SpringOne2GX 2014 early bird has been extended to June 30th, so register now! Without further ado, onward:

• Spring Boot 1.1.2 is now available! The new release features mainly bug fixes and more. Check it out!

• Adib Saikali gave a nice talk introducing where the rest of the Spring IO platform benefits from Java 8, above and beyond the uses we've previously described in Spring framework.

• Check out this replay of Spring Batch lead Michael Minella's webinar introducing Spring Batch 3.0

• Check out Glenn Renfro's introduction to using Spring Integration in an internet-of-things world

• Spring Data lead Oliver Gierke has announced the final service release for Spring Data Codd. This release contains bug-fixes that were already in the RC and GA releases of the Dijkstra release train.
