Kotlin call java method with Class argument

Question

I want to use Spring RestTemplate in Kotlin like this:

//import org.springframework.web.client.RestTemplate
fun findAllUsers(): List {
          


        

Answer 1

First, you will make a new class - UserList.kt (the name is our owner)

Inside:

class UserList : MutableList by ArrayList()

After that, you can call your method that has a RestTemplate

val response: List < Item > ? = restTemplate.getObject("yourEndpoint", UserList::class.java)

It may be returns null, so you need to take care of that.
