Hi all, in case you have missed it! 👋 In Kotlin 1.4.30 K, we've announced the Beta stage of the new JVM IR backed. This article describes what it is and why it's important to enable it. But let me repeat the article's central thesis here: please, switch on the JVM IR backend and build your project. And if you will face any problems, please use the YouTrack link or this Slack channel to submit your concern or ask a question. This version of the JVM backend compiler becomes a default one since 1.5. So, we need to test it very-very well, and for that, we call the Community for this kind of activity. And we hope you will answer our call. With love, Kotlin Team.

And how to do

Copy code

@Lock(LockModeType.PESSIMISTIC_WRITE)

for several methods in repo?

Anyone here running a spring-boot project with a ReactiveNeo4j and ReactiveMongo? I'm getting this

org.springframework.data.neo4j.repository.support.Neo4jEvaluationContextExtension@41ca08d6

even though I am working towards a MongoRepository 🤔

Boosting this SO question about Spring Validation. (I'm not the author.) Anyone see anything obvious here? https://stackoverflow.com/questions/66853644/validating-spring-pathvariable-in-kotlin-controller

Hi, which is the suggested approach to handle database migrations (i.e liquibase) with the Kotlin beans DSL? Maybe just starting Liquibase programmatically?

folks, i’m sorry, but there seems to be a misunderstanding this is a Kotlin slack there’s a spring entrypoing to discuss problems/issues/stuff regarding kotlin integration with spring here isn’t a spring general channel as @kqr pointed out, the spring team has a dedicated gitter for that https://gitter.im/spring-projects/ it’s not because your project is coded in kotlin that it makes it relevant (please look at the #android channel for example)

set the channel topic: Discussions on Kotlin specific integration with Spring, not Spring in general. For Spring-generic questions, try Gitter: https://gitter.im/spring-projects/. Spring Boot Kotlin guides: https://spring.io/guides/tutorials/spring-boot-kotlin/

Question about

spring-data-r2dbc

: is it possible to do paginated joins? Or really to filter by a joined table at all? The docs do not have an example.

Hi, I’m using Spring Boot 2.5.1 w/ Kotlin 1.4.32 and the Jackson

ObjectMapper

that’s being configured in

application.yaml

doesn’t appear to be the same one that’s being used by my

RestController

. I’m not getting pretty-printed JSON (for dev) and `Instant`s aren’t being formatted as strings, they are longs + nanos. Any help on where I can start debugging this?

Eric

06/23/2021, 2:59 PM

If I inject an

ObjectMapper

in my controller and log JSON generated by it, I get the expected formatting.

Eric

06/23/2021, 3:02 PM

sigh… just had to remove

@EnableWebMvc

from a

Configuration

How do I access my functional style declared beans in an Junit5 Test?

Copy code

beans {
    bean {
        Foo()
    }
}

Copy code

beans {
    bean("name") {
        Foo()
    }
}
