$ expression in @Client not resolved in Kotlin project

[abelsromero]

It seems to be the same issue reported in #1144 and supposedly closed.

Task List

• Steps to reproduce provided
• Stacktrace (if present) provided
• Example that reproduces the problem uploaded to Github
• Full description of the issue provided (see below)

Steps to Reproduce

1. Create new app with mn create-app junit-issue-demo --lang=kotlin --features=junit
2. Update dependency testCompile "org.junit.jupiter:junit-jupiter-api:5.1.0" to 5.3.0 or higher. Otherwise tests don't work
3. Add configuration to application.yml as follows:

jbcn:
  clients:
    cfp:
      endpoint: https://domain/endpoint

4. Create @singleton service

@Singleton
class CfpapiClient(
    @Client("\${jbcn.clients.cfp.endpoint}")
    @Inject
    val httpClient: RxHttpClient
) {

    @Value("\${jbcn.clients.cfp.endpoint}")
    lateinit var value:String

    companion object {
        @JvmStatic
        private val logger = LoggerFactory.getLogger(SpeakersController::class.java)
    }

    fun getAllSpeakers(): Flowable<MapSearchResult> {
        val req = HttpRequest.GET<Any>("speakers.json")
        return httpClient.retrieve(req, Argument.of(MapSearchResult::class.java))
    }
}

NOTE: MapSearchResult is a simple pojo

5. Add @controller that calls getAllSpeakers()
6. Start server
7. Invoke controller method

Expected Behaviour

The configuration property in @Client should be resolved and remote invocation of httpClient should work.

Actual Behaviour

The property does not seem to be resolved. It is correctly resolver however in the other bean property lateinit var value:String.
Note that everything works fine when setting the url directly in @Client

@abelsromero This is not the same issue because you're doing constructor injection and the issue you linked was using field injection
