oh, nevermind

didn’t realize that the spring template included

kotlin-allopen

np @igordonxiao. and yah actually i learned about the extension and plugin from spring boot

I used Kotlin with Spring and Spring MVC, not Sprint Boot, i’ll try

kotlin-allopen

extenstion later

does

kotlin-allopen

only affect those classes with Spring Boot Annotations?

yes, but you can register your own

hey everyone, does anyone have any recommendations on how to unit test your service layer implementation with Kotlin?

same as in java. junit 4)

maybe i should take a step back and look at java implementation first 😛

I’m trying to create a spring wrapper for a class that takes a constructor. I was trying to do it with delegation, but I’m stomped because the core class takes a dependency via its constructor. E.g:

interface A {
        fun methodA()
        fun methodB()
}

class MyClassA(var dependency: MyDependency): A {
        override fun methodA() { dependency.doSomething() }
        override fun methodB() { dependency.doSomething() }
}

Is there a way to do

@Service
open class MyClass: A by MyClassA

why you don't pass an instance of MyClassA in the constructor?

Delegates in Kotlin work with instances

hmmm, because I want that to be injected via spring.

yes

spring can do constructor injection

injected via Spring using a constructor argument

if you a single constructor you don't even need the

@Autowired

annotation

So, we are basically refactoring some libraries and adding spring. Originally everything was injected via constructors, but now they want to follow “spring conventions”. But instead of modifying existing classes, I just want to create spring wrappers around those

Yeah, that is the thing, my coworkers want to see

@Autowired

fighting some culture here

Spring convention is to use constructors

yeah, that is what I said

when is a needed dependency

ok, so the issue I’m having here is that I’m not sure how to pass in the inner dependency, e.g.:

@Service
open class MySpringAClass(var myClassA: MClassA(depsHere)): A by myClassA

I don’t know how to inject the dependency to myClassA in the constructor of the Spring Wrapper

your instance of MyClassA will be created by Spring too

including its dependencies

yes, but

myClassA

is not a spring artefact
