Spring Guides Move to Java 8

Perhaps you’ve noticed some recent articles lately?

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 to Java 8.


DevTools in Spring Boot 1.3

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:


or your Gradle build file:

Spring XD 1.2 GA, Spring XD 1.1.3 and Flo for Spring XD Beta released.

Today, we are pleased to announce the general availability of Spring XD 1.2, Spring XD 1.1.3 and the release of Flo for Spring XD Beta.

You can also install XD 1.2 using brew and rpm

The 1.2 release includes a wide range of new features and improvements. The release journey was an eventful one, mainly due to Spring XD’s popularity with so many different groups, each with their respective request priorities. However the Spring XD team rose to the challenge and it is rewarding to look back and review the amount of innovation delivered to meet our commitments toward simplifying big data complexity.


Spring XD Benchmarks Part 1


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.


This Week in Spring - June 16th, 2015

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 performance blog. And we haven’t even talked about the Amabari installer or the containerload of new features.
