what about vertx drivers?

Hello, I'm having a issue with transient fields: as I've seen in Java JPA @Document @Transient fields moved to use the transient java keyword, in Kotlin there's only the annotation. Is it supposed to work in Kotlin with @Transient or there is another trick to do that?

I created a different branch "exception"

I could set the default property value to an empty String as the example under, but still not quite optimal.

@Value("\${email.address.override:}")

^-- had to both unroll the method, and add JVMStatic

@sdeleuze link from header is 404 https://docs.spring.io/spring/docs/current/spring-framework-reference/kotlin.html

@Czar nice idea thanks, i haven’t explored spring profiles but seems reasonable, at least assuming it’s not a pita to setup for this 🙂

has anyone made integration tests for endpoints protected by jwt by chance? i am unable to get them to fail amazingly lol

also https://stackoverflow.com/questions/32970923/resolving-accidental-override-errors-in-kotlin

the videos are available already?

anyone have a good kotlin spring boot angular seed project? im getting started playing with things and thats the direction im going in

I remember from some time ago

@Value("\${provider.url:}") lateinit var urlString: String

worked.

I’m trying to add a nullable

@RequestParam

of type

Int

, but get

"Optional int parameter 'p' is present but cannot be translated into a null value due to being declared as a primitive type. Consider declaring it as object wrapper for the corresponding primitive type."

Any way I can force Kotlin to use the wrapper class Integer instead of the primitive type?

@gert.claeskens please be aware that your application entry point is the start point for the component scan (implictly implied by

@SpringBootApplication

), so that you either have to add the package of your

FooRepository

to the component scan packages, or put FooRepository in the same package or sub-package where

ReactiveKotlinApplication

lives, see https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-structuring-your-code.html for details

@gert.claeskens If you are going with the bean definition way, you can also probably declare your bean explicitly with

bean<FooRepository>()

and

bean<BarRepository>()

in the

beans {}

block.

I know this is not 100% spring related, but it is quite likely you bumped into this. I'm trying to annotate a delegated property with some jpa annotation and i get an error saying that a member property with delegate is not applicable:

@Column(name = "title", nullable = false)
var title by Verified(title, "The title cannot be blank", String::isNotBlank) // Verified is a Delegate.

reason was found - if Entity implements interface -

spring.jackson.property-naming-strategy=SNAKE_CASE

is not working 😞

AHA, so it is indeed spring's fault. I had this problems and ended up forcing 1.1.61 to all libs even the ones that should've been transitives. Thanks.

That's a feature that will avoid mixing various Kotlin versions 😉 It will be properly documented.

@sdeleuze which feature,

gradle.properties

or

ext['kotlin.version]

? i’d prefer the latter, since it centralized the kotlinVersion definition

Also be aware that unlike M6, M7 does not include

compile("com.fasterxml.jackson.module:jackson-module-kotlin")

so you have to add it back to your project dependencies. We will try to tackle that on start.spring.io side.

@leodeng yeah man, I dont really understand too, do you mind to have a look at my code? https://ander_dev@bitbucket.org/ander_dev/kotlin-jee.git

@Sola Could you give me more détails about those issues ?

So anyone else hanging out at https://springoneplatform.io/ ?

can I use spring webflux with spring boot 1.x?

@sdeleuze i know you’re probably busy now, but when you have time, can you look at this dependency-management plugin behavior: i accidentally set the

kotlin.version

to null (

ext['kotlin.version'] = null

), but the error reported is interesting:

* What went wrong:
Execution failed for task ':compileKotlin'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find org.springframework.boot:spring-boot-starter-webflux:.

there are no errors mentioning kotlin, and why would other dependencies resolution fail?

@sdeleuze Do you know if Spring Boot 2.0.0 GA plans is to release with Kotlin 1.2.x or 1.1.6x?
