Also someone suggested that all Kotlin Spring extensions should be

inline

for performance reasons (currently only those leveraging reified type parameters are), any thoughts on that?

@Peter - I agree. I do realise that @sdeleuze is very busy so I will sort this out myself. I am obviously doing something dumb.

hey all, this might be a tad off-topic as it's not strictly concerning spring + Kotlin, but does anybody know if there is a way to instantiate a @SpringBootTest once and then have multiple test classes that connect to it?

is there a way to do that?

hey there! how do you treat information not found in Kotlin? I’m doing

this.repository.findByIdOrNull

and when programming in Java I throw a Custom Exception (

ResourceNotFoundException

for example). What is a best practice to do this in Kotlin?

I was also missing the dependency management plugin

spring-plugin-core:1.2.0 from 2015…

Is there a separate Slack group specifically for Spring and all its various components? Or possibly something outside of Slack?

I have exactly the same problem as stated here: https://stackoverflow.com/questions/51152549/solr-fields-being-mapped-to-array-when-using-kotlin-and-spring-data-solr . Any idea on how to resolve that?

how do you set a column as

nvarchar

? The project is using

spring-data-jpa

. I’ve found some options:

@Nationalized

,

@Column(columnDefinition = ... )

,

type StringNVarcharType

Which one?

hey guys, I have been writing small tutorial like posts for springboot/webflux in kotlin and wanted to share: https://www.shiveenp.com/2019/04/21/Sending-Multipart-Form-Data-Using-Spring-WebTestClient-md/ any feedback/critique would be appreciated

mostly unrelated to kotlin (we use kotlin in lots of places, but not here currently), but was told I could post the question here to try and get some help. https://stackoverflow.com/questions/55975868/not-a-managed-type-spring-boot-tests

I have method that returns

Map<String, String>?

. This method is in a Custom Implementation for Spring Data Repositories (exactly as described here: https://docs.spring.io/spring-data/jpa/docs/2.1.6.RELEASE/reference/html/#repositories.custom-implementations). My problem: when I

return urlRequestResult?.value as Map<String, String>?

(using restTemplate to do the request here) it returns an

empty LinkedHashMap

, but if I evaluate it in debug mode it returns

null

(as I was expecting when

urlRequestResult

is null) Is it a bug or am I doing something wrong here?

this is a mix of a spring/gradle question. with the spring boot gradle plugin, is there anyway to copy the runnable jar to a different location and rename it? I've tried to do it with just a copy task, but that's messy because it depends on the project name. I'd rather just copy the single runnable jar without regex.

does kotlin in spring boot support jvmTarget > 1.8 (9/10/11) ?

Hi, I am migrating existing small app to spring boot and I'd like ask you a question. I used to use okhttp client to make http request for consuming REST and simple raw request to obtain html. What should be used in general in spring to make http request to obtain html, not some json from REST api. Is RestClient the way to go? The name is confusing.

guys, does

spring-fu

already support exception handlers with

WebMvc

?

@Configuration
@ConfigurationProperties(prefix = "schedule")
open class ScheduleProperies {

    var periodicDump: DumpSchedule? = null
    
    
    open class DumpSchedule {
        /**
         * in seconds
         */
        var interval: Int? = null
        /**
         * in seconds
         */
        var offset: Long? = null
    }
}

is it possible to make a Bean out of

DumpSchedule

?

Bug report: After upgrading from Kotlin 1.3.21 to 1.3.31, I cannot do anymore

if (object == null)

for java classes like

org.springframework.data.mongodb.core.query.Criteria

who redefine

public boolean equals(Object obj): Boolean

and forgot the

@Nullable

annotation, while the package is marked at

@NonNullApi

. Work around:

if (object === null)

is working

are there any kotlin extensions for spring data JPA's streaming API that make it use kotlin collection types, or should i just stick with java.util.Stream in kotlin?

to the kotlin-maven-plugin plugin. Could you tell me why it is required?

@sdeleuze until Actuator is officially supported with Kofu, is there a simple workaround to get Actuator working in Kofu app?
