Spring RestTemplate and generic types ParameterizedTypeReference collections like List

Question

An Abstract controller class requires List of objects from REST. While using Spring RestTemplate its not mapping it to required class instead it returns Linked HashMAp

Answer 1

In case someone need a Kotlin solution, you can do:

val responseType = object : ParameterizedTypeReference>() {}         
val request = HttpEntity(data)
val response = restTemplate.exchange(url, HttpMethod.POST, request, responseType)
val responseMap = response?.body as Map
