I get the initial problem again (IllegalStateException: Failed to resolve argument 2 of type '[B'… caused by the UnsupportedOperationException, as ByteArrayDecoder doesn't implement

decodeToMono

)

Will be fixed in Spring Framework

5.0.3

: https://jira.spring.io/browse/SPR-16253

Already fixed in master

sdeleuze

So it will be available in Boot

2.0.0.RC1

sdeleuze

For now indeed use

Flux<ByteArray>

That's awesome 🙂

I'll just add a

//TODO

to clean it up when I upgrade to Boot 2.0.0.RC1

sdeleuze

12/21/2017, 1:02 PM

👍

Hey, when using a

Flux

it even works without the manual

ByteArrayDecoder

configuration. My trust in Spring Boot is restored 😀

sdeleuze

12/21/2017, 1:15 PM

Indeed it is configured by default 🙂

Hello. I have a (spring) kotlin project that imports (maven) another (spring) java project. The problem is that everything I imported from this java project fails with

Unresolved reference:

in the Intellij IDE everything works when I run

mvn clean install

then everything breaks

The problem was in maven. Solution here https://kotlinlang.org/docs/reference/using-maven.html#compiling-kotlin-and-java-sources

Hey guys, I need some advice on a good approach to implementing a rest repository to an external service. If there's a good guide/resource I would really appreciate it. At the moment our repositories are entirely JPA repositories and moving forward we'll have multiple sources of data in the application and need a neat way to manage it.

Hi, I pushed an example on GitHub, but it's with spring data mongo. https://github.com/adrienpessu/kotlin-spring-api-jwt-example

How can I mock with mockito a method with a nullable argument and

any

any() doesn’t work very well with Kotlin, you have to use something like this: https://github.com/nhaarman/mockito-kotlin/blob/master/mockito-kotlin/src/main/kotlin/com/nhaarman/mockito_kotlin/Mockito.kt#L47

dariuszbacinski

01/10/2018, 3:41 PM

you can copy any() implementation or just import mockito-kotlin to your project

Yeah, didn't work for me but I've found another solution that opens the functions with an annotation

ziggy42

01/10/2018, 3:46 PM

I'll try it again when I'll have some time
