(check JARs in Idea dependencies for example)

@sdeleuze here is my stacktrace: https://pastebin.com/9i7gXjLY

everywhere in my project is 1.2.0

See https://github.com/FasterXML/jackson-module-kotlin/issues/97

@hho its works for me too, thanks!

@sdeleuze Who do I have to nag so that Spring Boot will include dependency management for

kotlin-stdlib-jdk{7,8}

? Currently they're only managing the

-jre

variants? (https://github.com/spring-projects/spring-boot/blob/b6aa0f24e2d1ea371d12741182a946623c8d08e0/spring-boot-project/spring-boot-dependencies/pom.xml#L2224-L2233)

Is it the new dependency artifacts for Kotlin 1.2 ?

Do they replace jre variants ?

No, it seem they're additional variants for apps targeting a JDK instead of a JRE. I discovered those by accident, because the IDEA Plugin added the

-jdk

variant to my POM, which then wasn't version managed anymore.

https://kotlinlang.org/docs/reference/using-maven.html says:

If you're targeting JDK 7 or JDK 8, you can use extended versions of the Kotlin standard library which contain additional extension functions for APIs added in new JDK versions. Instead of kotlin-stdlib, use kotlin-stdlib-jdk7 or kotlin-stdlib-jdk8, depending on your JDK version (for Kotlin 1.1.x, kotlin-stdlib-jre7 and kotlin-stdlib-jre8).

Oh, they only exist since 1.2.0

So Boot probably can't add them yet.

(I sincerely hope they switch to Kotlin 1.2.0 before their Boot 2.0.0 release, though)

It is the plan, but we are discussing dependency management right now because the situation with Gradle is not ideal since we need to have to specify Kotlin version for the plugin

Where with Gradle we can specify plugin + deps in parent POM which is much more consistent

anyone keen to help me with spring boot integration test?

just in case, my issue is that I run kotlin as a war in wildfly env. when I try to run my integration test it come up with this error Caused by: org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean. sure, I had to disable its embedded server as I ran it on wildfly

How do I get Boot 2.0.0.M7 to decode my

@RequestBody

as a

ByteArray

? (using webflux with annotations)

I tried registering a codec, but it doesn't seem to work.

I only get

Failed to resolve argument 2 of type '[B' on public org.springframework.http.ResponseEntity<java.lang.Object> mypackage.MyController.store(java.lang.String,java.lang.String,byte[])

Can you show your "controller" method?

Really not a lot in it

This seems to be the root cause.

I don't understand it, though – if the

ByteArrayDecoder

doesn't support

decodeToMono()

, how am I supposed to use it for request data?

Hm... maybe something wrong with

Content-Type

header of the request?

I don't think so, as

ByteArrayDecoder

claims to support all MIME types (

*/*

), which makes sense.

I'm still a newbie with the reactive stuff – it seems, the body has to be a

Flux<ByteArray>

, maybe because it could be transferred chunked?

Could you debug

org.springframework.core.codec.ByteArrayDecoder#canDecode

to see what class is detected ?

This seems to work now

It really has to be a

Flux
