loudspeaker hello folks We are in process of updating the Spring Kotlin tutorial in our documentation I think it s a good time to ask for the feedback from the community We don t plan to make it super comprehensive though the goal is rather to show how to get started with Kotlin in the Spring projects and cover some of the obvious use cases Here I have the first draft Please let me know what do you think about in the thread thread please

Is there a link somewhere to the final Github repo Or even better a <https docs github com en repositories creating and managing repositories creating a template repository|Github template>

antonarhipov · Answer

So far only this only with the final code state There are the intermediate commits as well though <https github com antonarhipov kotlin spring demo>

mbonnin · Answer

Nice I d put the link as a preamble

antonarhipov · Answer

I will probably split the repository into branches for each stage of the tutorial in the final version

mbonnin · Answer

That d be nice althoug TBH a lot of work sweat smile

antonarhipov · Answer

it s for the good cause wink

mbonnin · Answer

Yup slightly smiling face

Emil Kantis · Answer

I mean Spring Initializr puts some outdated stuff into the gradle files I would raise an issue or contribute a fix to that Or at least mention what it does wrong in the guide

antonarhipov · Answer

< Emil Kantis> can you give an example I can t recall anything like that atm

Emil Kantis · Answer

Also it would feel more kotlin to me to use Webflux and DSL routing rather than annotation driven code But I guess it depends on the audience slightly smiling face

Emil Kantis · Answer

```mplementation org jetbrains kotlin kotlin reflect Kotlin reflection library required for working with Spring implementation org jetbrains kotlin kotlin stdlib jdk8 ``` Adding stdlib is no longer needed gradle plugin adds it automatically and I would change the kotlin reflect dependency to `implementation kotlin reflect `

antonarhipov · Answer

Yeah Webflux is not something we want to throw at the users right from the beginning I think We do plan to develop this tutorial further so yeah I think we will bring in the dsl a bit later

if your goal is to get more people using kotlin and spring i recommend looking at it from the lens of how to get java and kotlin to coexist in a spring environment kapt But also higher priority at least for me is how to get hibernate JPA to play nicely with kotlin And I mean real world entities not everything is so simplistic wee we stored 2 strings and it s so nice that I frequently see I ve had to scour a crazy number of resources to get the information I needed just to convert my hibernate JPAs over to kt Many would say totally different things Then I ran into an Intellij bug which is unfixed for embeddable entities that gives a false positive for an inspection And right now I m running into a failure of smart casting because of the all open plugin which i m wondering if there s a workaround for

I would suggest adding ` Column` to show custom names many organizations have specific naming conventions or may be using existing existing tables Also create separate interface for MessageService so that Controller depends on interface and not implementation

sdeleuze · Answer

Nice maybe renaming `MessageResource` to `MessageController` would be more idiomatic

sdeleuze · Answer

I like the fact you use Spring Data JDBC

sreich · Answer

i agree with the ` Column` be more in line with what most people are doing including my orgs code

sdeleuze · Answer

You could use Kotlinx Serialization and exclude Jackson dependencies
