Hi, Spring fans! Welcome to another installment ofThis Week in Spring! In the last week I went from Germany (for JAXON) to Linz, Austria (for DevOne) and Vienna, Austria (for a meetup) and now I'm in Melbourne, Australia (after a 10 hour stopover in Bangkok, Thailand), for the VOXXED Melbourne event. As usual, if you're aroundI'd love to hear from you!
Without further ado, we've got a lot to cover so let's get to it!
- Pivotal just turned 5!Happy birthday to us!
- Spring Cloud contributor Ryan Baxter has just announced Spring Cloud Finchley RC1. The new release ispackedwith all sorts of new stuff and represents one of hopefully thefinal releases before Spring Cloud Finchley before it's GA.
- Hi, Spring fans! In last week's installment of Spring Tips I looked at how to extricate process state - valuable for coordinating long-running or mutli-actor processes — from business logicwith Spring Statemachine.
- TheRabbitMQ 3.7.5-beta2 is now available.
- I really like this Chinese-language post on whether Spring Boot and Spring Cloudcan be used by small and medium-sized companies.
- The RabbitMQ blog has a nice post on using theMicrometer integration in the RabbitMQ Java client to integrate with Datadog.
- Jeroen Reijn gave a nicepresentation on test-driven Spring REST Docs-based documentation.
- The Ordina blog has a nice post on usingSpring Cloud Contract to support consumer-driven contracts.
- I love this post by Gaurav Guptaon synchronous request/reply with Apache Kafka and Spring.
- The Baeldung has another interesting post (related to Servlets) thatlooks at the
@ServletComponentScanin Spring Boot: it detects all Servlet APIWebFilter,WebListener, andWebServletannotations on servlet components. - This is an oldie-but-a-goodie from the Baeldung blog:a Quick Intro to the
SpringBootServletInitializer, which is the mechanism that let's Spring Boot applications run in a Servlet container setup, as opposed to a fat-.jar. - Donotmiss this newguide on Spring Cloud Gateway.
- Bartosz Jedrzejewski put together a nice post on using Reactor (in a Spring WebFlux application)to obtain parallelism and backpressure.
- And yet another Baeldung post, this time with areview of the state of Java. The numbers in this year's survey are very interesting! The numbers are very promising: Java 8 is now, by far, the majority deployed version of Java. Java 9 and 10 are gaining ground, though! Also interesting: Spring Framework 4 and Spring Framework 5 are, by far, the majority deployed enterprise Java framework. The precise numbers aren't clear, but it looks to be almost 75% of the pie-chart. Java EE and "Other" technologies account for what I'd guess is 20% of the remaining deployments, followed by Spring Framework 3, which looks to be about 5% or so (Maybe less?) Of the deployments that are based on Spring, a majority are based on Spring Boot, with less than 20% or so based on Spring without Spring Boot. IntelliJ, Apache Tomcat, and Maven are the clear leaders, too. Also interesting: Groovy, Kotlin, and Scala (in that order) are the leaders in non-Java languages.
- The Heroku documentation has a great list of steps that are required to make a Spring Boot application cloud-ready. This blog was published on the Heroku blog but a lotof it applies to building cloud-native applications for any platform.
- This post demonstrateshow to test in a Spring applicationwithoutSpring. It sets up a scenario thatshouldbe very uncommon, field injection, and demonstrates how adversely this affects the goals of testing. Remember what I always say: "every time you do field injection, a unit test dies!" The post then looks at how to test components, and to even remove Spring from the testing process.
- Nicolas Frankel looks at changes inSpring Boot 2's Actuator.
- I love thischeat sheet on using Java 10.
- The Spring Cloud team is hiring!Join us!
- Michael Simons and Michael Plödput together a nice German-language slidedeck on Spring Boot 2.
- TheAll and Sundryblog has anice post on configuring a simple route with Spring Cloud Gateway
- Part two of my series on building reactiveSpring-based applications is now available in Java Magazine.
- TheJava Revisitedblog has a nice post onthe motivations for pursuing certification in Spring Cloud.
- The call-for-papers for the inauguralRabbitMQ Summit on November 12th, 2018 at CodeNode in London, UK is now open!
