Sure i’m using 2.0.0.M4 I will double check

using*

Please use `2.0.0.M5`released yesterday

ok

It leverages Spring Data Kay GA

Thanks

If it works if you don't mind I will ask you to create a SO question and I will answer there since a lot of people are going to ask this question 😉

Sure thanks

Can someone explain why I’m getting this warning? The code works, and the same format in a @Controller does not display any warning.

you don’t need the val there since you are using only the attribute, you would have to add the (private…) val only in case if you call this dynamoDBConfig in any of the methods

ah, thanks

it just felt weird. Would be nice if intellisense added that information to the error message. It displays a rather informative pop up with why it is “bad” to add the “val”, but doesn’t provide a work around.

I’m getting pretty picky about error messages, more and more I’m convinced that they should also suggest solutions.

thanks for the tip, it works without the

val

, I’ll have to document that in my commit message.

👍

Has anyone used Spring sleuth with Kotlin coroutines? I ask because the code

@RequestMapping("/concurrent1")
  fun endPoint1() : String {
    <http://log.info|log.info>("/concurrent1")
    var s = ""
    runBlocking {
      val a = urls.map { url ->
        <http://log.info|log.info>(url)
        async(CommonPool) {
          restTemplate.getForObject(url, String::class.java)
        }
      }
      val b = a.map { it.await() }
      s = b.joinToString { "" }
    }
    return s
  }

records a unique trace for each HTTP call when sent to a Zipkin server. I suspect it’s something to do with coroutines running in a separate thread from the main thread.

hello, anyone knows if there is some issue with bean names and Qualifier annotation in Kotlin? shouldn't this work?

@nicolay.mitropolsky commented on @villela’s file : yes. and does work for me. pleas tell the version of Kotlin and IDEA.

@sdeleuze bad news

every time that I try to create a new repository method returning a nullable object

i'm receiving this exception

I'm going to prepare a demo project to reproduce the problem and create a SO question

I will send the link here soon

I think you can directly create an issue if possible with a repro project on https://jira.spring.io/browse/DATACMNS

ok

@sdeleuze sorry I was creating the sample project here but actually, the problem was in my query I put a different object to return from the method, this was causing the exception above. I'm going to publish the repository to leave as an example. https://github.com/tiarebalbi/spring-data-kotlin-nullable-query the nullable query it's working as expected!

@villela commented on @villela’s file : it was on my laptop but here in my desktop with 2017.2.5 and the EAP plugin it is working as expected. Kotlin is 1.2-M2 and spring 2.0.0.M5 in both computers

@villela commented on @villela’s file : probably just a version mismatch in the laptop them I guess

@villela did you added the class to your project context?

@tiare.balbi do you have the original code somewhere? A deeply nested NPE is unfortunate and I’d like to see whether we can do something about it
