Why do you prefer spring over vertx? I would think it depends on the project...

@kenkyee we already have a talent pool of spring-engineers, so it is a natural fit. am not commenting whether spring is better/worse than vertx.

@User uploaded a file: and commented: Hi there, I juste updated my spring boot kotlin projet and I got a "18:47 Gradle sync failed: Spring Boot plugin requires Gradle 3.4 or later. The current version is Gradle 3.3" event if gradle 3.4.1 is selected. Any idea ?

@emmanuelvinas commented on @emmanuelvinas’s file : The user .gradle configuration was the problem cause.

I had similar issue while upgrading to Gradle 3.5 and its new cache

So yeah worth to know, in case of issue remove your

.gradle

And if that don’t works, remove

.gradle/cache

in your home directory

I hope new cache will be more reliable

what's the current state of coroutines in spring? I'm a total spring noobie but I managed to get it working using `ListenableFuture`:

@RequestMapping("/foo/bar")
fun index(): CompletableFuture<Menu> = future {
    baz.doSuspendingThings()
}

is there a way to just make the mthod

suspend

so that I can omit the

future

part?

Convince @sdeleuze that coroutines make sense in Spring 🙂

I'm working with ASP.NET in my day job and everything is

async

over there. If it makes sense in C#, why shouldn't it in Kotlin?

.Net also has Rx... Surprised you're not using that too

how to use kotlin data class in Spring mvc get mapping

I use standard data classes 🙂

@User uploaded a file: Untitled

@lex it fails

no default constructor

in some cases, when I use mapping tools like mapstruct for map entities to dto, class fields should be nullable with default null value

@User uploaded a file: Untitled

yes, using

var

field in data class works

@douglarek yes it can fails with non null fields if no incoming data

this is expected behaviour

thanks

@kirillrakhman I have a PR to review, I will have a look before Spring 5 RC2 https://jira.spring.io/browse/SPR-15413

Also see Reactor support at https://github.com/Kotlin/kotlinx.coroutines/tree/develop/reactive/kotlinx-coroutines-reactor

Same for that I will have a deeper look before Reactor 3.1 GA (expected in June)

thanks for that link @sdeleuze 🙂

we are using kotlin with spring boot and it is a very nice stack i must say

Glad you like it 🙂
