This is an IntelliJ Spring support issue https://youtrack.jetbrains.com/issue/IDEA-139669 unfortunately we cannot (yet) evaluate all beans “as at runtime” completely. You can switch off that inspection to avoid false warnings.

no suitable constructor found, can not deserialize from Object value

when using data classes on a

@RequestBody

@e.lislebo assuming the filename is

MyKotlinClass.kt

, you should be using

com.sportradar.MyKotlinClassKt.main

Good Morning! I need some advice, because I'm stuck and I'd highly appreciate any input 🙂 My main project is Java + Spring Boot 1.5.4. I have a second project in Kotlin + Spring Boot 2.0.0.M3, which is using Entity classes from my main project, as in this repository:

package com.alphabrik.inditex.instore.import.io.readers

import com.alphabrik.inditex.instore.web.entity.stores.Area
import org.springframework.data.repository.CrudRepository

interface AreaRepository : CrudRepository<Area, Long>

When I compile and run this with IntelliJ, everything works like a charme. The problem occurs, when I try to compile this with Maven - it tells

[...]\AreaRepository.kt: (3, 38) Unresolved reference: web

and

[...]\AreaRepository.kt: (6, 43) Unresolved reference: Area

I started the Kotlin project with the config from start.spring.io Any ideas? Thanks in advance 🙂

Please post if you find the reason, it's curious.

I think I have finished the Kotlin reference documentation (improved organiation, updated info on

@ConfigurationProperties

and function bean registration with Boot, additional section about annotations), feel free to have a look (https://docs.spring.io/spring-framework/docs/5.0.0.BUILD-SNAPSHOT/spring-framework-reference/kotlin.html#kotlin) and to propose fixes via pull request on https://github.com/spring-projects/spring-framework/pulls (asciidoc source is https://github.com/spring-projects/spring-framework/blob/master/src/docs/asciidoc/kotlin.adoc)

If you want an object with name you can use something like

@Query("select new com.packageName.SomeDTO(field, field, field, name) from ...")

@pavel I have added a new section about JPA in Spring Framework 5 ref doc https://docs.spring.io/spring-framework/docs/5.0.0.BUILD-SNAPSHOT/spring-framework-reference/kotlin.html#using-immutable-class-instances-for-persistence

In the [Requirements](https://docs.spring.io/spring-framework/docs/5.0.0.BUILD-SNAPSHOT/spring-framework-reference/kotlin.html#requirements) paragraph, I wouldn't list the different

stdlib

variants. As Spring 5 has a JRE8 baseline anyway, I would [only] require the

kotlin-stdlib-jre8

version.

@sdeleuze congratulations on Spring 5!

Hello! Does anyone have any recommendations for a guide I can follow to setup authentication for a restful API backend written in Kotlin/Spring Boot?
