Rarely we blog about a single feature, but given that this one was one of the most requested ones in Spring Cloud Function (relatively young project), we thought it may be appropriate, so here it is.

Initial support for Kotlin lambdas has been added to Spring Cloud Function. What it means is that Spring Cloud Function can now recognize Kotlin lambdas that effectively match to one of Java’s Supplier, Function or Consumer and treat them as such.

That is:

@Bean
open fun kotlinFunction(): (String) -> String {
    return  { it.toUpperCase() }
}

@Bean
open fun kotlinConsumer(): (String) -> Unit {
    return  { println(it) }
}

@Bean
open fun kotlinSupplier(): () -> String {
    return  { "Hello Kotlin" }
}

On behalf of the Spring Data team, I’d like to announce the availability of the Ingalls SR15 and Kay SR10 maintenance releases. Kay SR10 ships on top of the just-released Spring Framework 5.0.9. Spring Boot 2.0.5 is going to pick up Kay SR10 for your convenience. Ingalls SR15 will be picked up by Spring Boot 1.5.16. Both releases ship with mostly bugfixes and a few dependency upgrades.

Ingalls SR15 ships with 40 tickets fixed and Kay SR10 contains 75 issues fixed.

Also, make sure you register for this year’s SpringOne Platform (Sept. 24th-27th, Washington, D.C.) to learn about the latest additions in Spring Data and even get a preview of the features planned for the next release train. The entire team will be on site and happy to answer questions and take feedback.

Hi Spring fans! In this brief 8 part series we’re going to look at the Spring Cloud integration for Google Cloud Platform, called Spring Cloud GCP. Spring Cloud GCP represents a joint effort between Google and Pivotal that endeavors to provide a first class experience for Spring Cloud developers when using the Google Cloud Platform. Pivotal Cloud Foundry users will enjoy an even easier integration with the GCP service broker. I wrote these installments with input from Google Cloud Developer Advocate, and my buddy, Ray Tsang. You can also catch a walkthrough of Spring Cloud GCP in our Google Next 2018 session, Bootiful Google Cloud Platform. Thanks buddy! As always, I’d love to hear from you if you have feedback.
