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

Couldnt find a solution from Spring, hence I have done it with ParameterizedTypeReference in HashMap like

 public final static HashMap paramTypeRefMap = new HashMap() ;
 static {
    paramTypeRefMap.put(AttributeDefinition.class, new ParameterizedTypeReference>(){} );
    paramTypeRefMap.put(AttributeInfo.class, new ParameterizedTypeReference>(){} );
 }

and used it

ParameterizedTypeReference parameterizedTypeReference = paramTypeRefMap.get(requiredClass);
ResponseEntity exchange = restTemplate.exchange(uri, HttpMethod.POST, entity, parameterizedTypeReference);
