Welcome to another installment of This Week in Spring! As usual, we've got a lot to cover so let's get to it! This week I'll be in Shanghai, China, talking to some customers (say hi on Twitter!) and then it's off to Shenzhen, China, where I'll be giving a keynote at the ArchSummit conference.

• Spring Integraton lead Gary Russell has just announced Spring Integration 4.2 and 4.1.6 are now available. The new release includes support for Apache Zookeeper, Java 8 CompletableFutures, (S)FTP -streams, and several performance improvements.
• Spring Boot co-lead Phil Webb has just announced Spring Boot 1.2.5.

Welcome to another installment of This Week in Spring! I was in London, last week, for Devoxx UK. The show was a rousing success all around. I gave a talk, a workshop, and was delighted to participate in the closing keynote, too! This week I'm in Kraków, Poland, for Devoxx Poland (né 33rd Degree) which seems to be an amazing success as well! I want to thank the organizers (Mark Hazell and Grzegorz Duda of Devoxx UK and PL respectively) for inviting me - I haven't had this much fun in a while and I love the communities that both events serve.

In addition to being in the keynote, I was…

Perhaps you've noticed some recent articles lately?

• Spring 5 moving up to Java 8+
• Massive adoption of Spring 4 and Java 8
• http://start.spring.io/ defaulting to Java 8 as the version of choice
• Spring Boot's 1.3.0.M1 reference docs recommending new apps start at Java 8.

Okay, those last two aren't articles, but were instead driven by the the rapid adoption of Java 8. Java 8 has been picked up by the development community FAST. Here on the Spring team, we believe strongly in adopting Java 8 for new applications. To support that and improve your own ability to move as well, we just updated all of the Spring Getting Started Guides…

#Introduction#

A common question when developing streaming applications is, “How many events per second can you process?”. The primary purpose of this blog post is to answer that question without falling into the classic benchmarking conundrum of benchmarking versus "benchmarketing". The common approach with 'native' benchmarking applications provide by messaging middleware vendors is to focus on raw data transport speed, without serialization or deserialization of the message data and without any data processing. In Part 1 of the series, we will follow this approach.

Our tests used direct…

Welcome to another installment of This Week in Spring! This week I'm in sunny London for Devoxx UK where I'll be talking to developers about building cloud-native applications with Spring Boot, Spring Cloud, and Cloud Foundry. As usual, if you're in the area, hit me up. The big news this week is the Spring XD 1.2 GA blowing the doors off performance numbers! No benchmarketing here, everything is published and reproducible: Performance turning to get ~12 MILLION msg/sec with an in-memory transport and 2.6MILLION msg/sec when using Kafka (100 byte messages). Lots more detail in the …

Spring Boot 1.3 will ship with a brand new module called spring-boot-devtools. The aim of this module is to try and improve the development-time experience when working on Spring Boot applications.

To use the module you simply need to add it as a dependency in your Maven POM:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>
</dependencies>

or your Gradle build file:

dependencies {
    compile("org.springframework.boot:spring-boot-devtools")
}

Once included, the spring-boot-devtools module provides a number of nice features that we cover below (If you can't be bother to read the text, skip to the end of the post for a short video…

Over the past year, we have significantly improved the cache abstraction, with support of JSR-107 (JCache) annotations and a better declarative model to share or externalize common settings. In Spring Boot 1.3, we now offer a comprehensive auto-configuration for it.

In a nutshell, the cache abstraction applies caching to methods, thus reducing the number of executions based on the information available in the cache. The caching logic is applied transparently: the method below will only be invoked if the specified ISBN is not already present in the books cache. Upon calling that method for a missing Book, the caches will be updated transparently so that a further call does not invoke the…

This post is a guest post by community member Tadaya Tsuyukubo (@ttddyy), creator of the Spring Social Slideshare project. Thanks Tadaya! I’d like to see more of these guest posts, so - as usual - don’t hesitate to ping me! -Josh

Spring Social Evernote is one of the community modules in the Spring Social ecosystem. It is a service provider implementation for Evernote. It allows developers to work with the Evernote SDK for Java with idiomatic Spring idioms.

Evernote takes a unique approach for providing their APIs to developers. They have created language specific SDKs based on Thrift serialization format. Dave Engberg, CTO of Evernote, explained the motivations for choosing Thrift in this blog…
