I have a spring @Component and want it to have a delegate, something like this

@Component class Service(val list: ArrayList<String> = emptyList()) : List<> ... by list

Spring thinks that I’m injecting a bean and throws No qualified beans… How to solve it?

I don’t want list to be a bean

Have a separate constructor annotated with

@Autowired

maybe?

fiddling with the kotlin router dsl

@nfrankel uploaded a file: Untitled

from the documentation: https://docs.spring.io/spring/docs/5.0.0.BUILD-SNAPSHOT/spring-framework-reference/kotlin.html#webflux-functional-dsl

how to get the handle on the

userHandler

? trying to inject it with

ref()

with no success since it’s not inside a

bean

block

i created a class to wrap the

router

block and used it in the main

beans

block as

bean(WebHttpHandlerBuilder.WEB_HANDLER_BEAN_NAME) {
        RouterFunctions.toWebHandler(PersonRoutes(PersonHandler(ref())).routes())
    }

no more success

I have proposed to Spring Data team to add a

findByIdOrNull(id: ID): T?

extension to

findById(id: ID): Optional<T>?

https://jira.spring.io/browse/DATACMNS-1346

does anyone else have problems with the kotlin-spring gradle plugin? For me sometimes it decides to stop working so that I get the "cannot subclass final class" errors, any ideas to make it work consistently?

nvm, it was the stupid idea plugin, updating to 50 did the job

Is there any way to get spring-boot's version in maven?

I need to set something else to the version

2.0.3.RELEASE

${project.parent.version}

?

Hey! I've been playing with SpringBoot 2 with WebFlux and found interesting issue - https://github.com/reactor/reactor-core/issues/1273 Have you seen smth like that?

Hey guys. I have an issue with Kotlin and Spring. Kotlin NoArg plug-in is not creating default constructor. I already asked on SO https://stackoverflow.com/questions/51352067/noarg-constructor-is-not-getting-created Thread in Slack Conversation

Why do you need noarg plugin since Spring Framework 5 is expected to deal natively with Kotlin data classes?

I have some ideas for

spring-fu

and was wondering if doing compile time annotation processors to generate implementations from an annotated repository will go against the aim of the project? My thinking was it will be possible to generate an implementation that does the same kind of work as what currently happens in Spring Data but no proxies or reflection involved.

I've been experimenting with Spring Fu further and have been getting a runtime exception when I use a seperate route class.:

Exception in thread "main" java.lang.IllegalStateException: org.springframework.context.support.GenericApplicationContext@5cc7c2a6 has not been refreshed yet

The exception does not happen if I wire the routes directly in the application class. Here is some example code and the full stack trace: https://gist.github.com/ciferkey/02be73b8dd18add59c8d63b528c79a12 Any thoughts why?

Likely do to https://github.com/spring-projects/spring-fu/commit/bdb9c24df337fcf677a963d34a3a056981f2d30e I will have a look thanks for reporting

Should work with that, I will see later if i can do something else. https://github.com/spring-projects/spring-fu/commit/f7309ac0c11659fc3acd16081ba841a78ae398a6

I'm busy playing with Spring Fu and ran into problem. I have a project https://github.com/corneil/reactive-spring-5 with multiple sub project. It was initially done to illustrate Spring 5 Reactive support and has non-reactive web project as well. I recently added a reactive Kotlin version and then started the spring-fu version. The mongo template doesn't seem to load responses even though the queries are the same.

2018-07-21 13:56:36.112  DEBUG --- [ctor-http-nio-2] o.s.d.m.core.ReactiveMongoTemplate       : find using query: { "timestamp" : { "$gte" : { "$date" : 1529582195915 }, "$lte" : { "$date" : 1532174195915 } } } fields: Document{{}} for class: class com.github.corneil.model.LocationHistory in collection: location_history

Turns out the

spring.data.mongodb

are not read. Using correct connection string solved the problem.

depends on the kind of requests that are made.

If you want to contribute an easy PR to Spring Fu that solves a concrete problem, see that one https://github.com/spring-projects/spring-fu/issues/88

I have a

ConfigurationProperties

with a certain field

a

. I have an external library (that I cannot replace in any way) that at some point requires the name of an implementation of an

Interface

. This is the implementation:

class ClientHandler : CallbackHandler {

        override fun handle(callbacks: Array<Callback>) {
            (callbacks[0] as SpecificCallback).a = a
        }
    }

a should be accessible here

How would you do it?

I performed my benchmarks on Ubuntu on the same hardware and the results are very different from Windows. https://github.com/corneil/reactive-spring-5

when I use

jdbcTemplate.queryForObject(sql, parameters, Long::class.java)

I get an warning "Expected type does not accept nulls in Kotlin, but the value may be null in Java" how to fix?
