This Week in Spring – Only Infotech19th, 2018

Hi Spring fans! Welcome to another wonderful and wild This Week in Spring! This week I’m in Amsterdam, NL (visiting customers); London, UK (for both the London Java Community Java User Group talk and the SpringOne Tour event); Paris, FR (for the first JHipster Conf); Krakow, PL (for Devoxx Poland) and then it’s off to Sao Paolo, BR (for the Spring Connect show). If you’re in any of those places, say hi!

  • Spring Cloud Finchley.RELEASE is available. This is the big one! It’s finally here! The final piece of the reactive puzzle. This release culminates an almost year long journey from Spring Framework 5 (released in September of 2017) which introduced the world of Spring to reactive programming. Then we saw Spring Data Kay, Spring Cloud Stream, Spring Security 5, Spring Boot 2 (just a few months ago) and now, finally, Spring Cloud Finchley all embrace reactive programming wherever it makes sense. Spring Framework 5 is the new baseline and with it comes a new Java baseline requirement; Spring Cloud Finchley assumes Java 8 or better. This release is not just a refresh, though! Furthest thing from it! This release also includes two (effectively) brand new projects called Spring Cloud Function and Spring Cloud Gateway. Spring Cloud Function supports serverless programming and Spring Cloud Gateway is an API Gateway.
