The Spring Blog

Hi Spring fans! Welcome to another installment of This Week in Spring! It’s the week before SpringOne Platform and things are crazy! We have so much to cover - as usual! - but FIRST! ..some poetry (with apologies to Clement Clark Moore)

’twas the week before SpringOne Platform, when all throughout Spring;
Not a creature was stirring, just the computers and things;
the expectations were raised by the community with care;
in hopes that SpringRod would be there;

That’s right! this year is fixing to be AMAZING! We’re going to have Spring founder Rod Johnson, Jenny Zhang, Siew Choo Soh, Neha Narkhede, Matt Raible, Ray Tsang, Lauren Knausenberger, Juergen Hoeller, Bruno Borges, Andrew Clay Shafer and allllll the rest of the Spring team! It feels like a minute ago (December!) that we just had the last one so I can’t believe how quickly this one has arrived, but I can’t wait!

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.

It is my pleasure to announce that Spring Boot 2.0.5 has been released and is is now available from repo.spring.io and Maven Central.

Spring Boot 2.0.5 includes 87 fixes, improvements and dependency updates (including an important security fix for Spring AMQP). Thanks to all that have contributed with issue reports and pull requests.

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" }
}
