spring restTemplate 返回泛型

有个这样的类:

public class Wrapper {

 private String message;
 private T data;

 public String getMessage() {
    return message;
 }

 public void setMessage(String message) {
    this.message = message;
 }

 public T getData() {
    return data;
 }

 public void setData(T data) {
    this.data = data;
 }

}

ParameterizedTypeReference> typeRef = new ParameterizedTypeReference>() {  
};  
ResponseEntity> responseEntity = restTemplate.exchange(url, HttpMethod.POST, new HttpEntity<>(mvm), typeRef);  
List myModelClasses = responseEntity.getBody();
