Title Body

I have a class like that: public class Wrapper<T> { 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; } } and I use resttemplate as follows: ... Wrapper<Model> response = restTemplate.getForObject(URL, Wrapper.class, myMap); Model model = response.getData(); ... However it throws a: ClassCastException I read that: Issue when trying to use Jackson in java but didn't help. There are some topics related to my problem etc.: https://jira.springsource.org/browse/SPR-7002 and https://jira.springsource.org/browse/SPR-7023 Any ideas? PS: My error is that: java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to a.b.c.d.Model I think resttemplate can not understand my generic variable and maybe it accepts it as an Object instead of generic T. So it becomes a LinkedHashMap. You can read from it here It says that when explaining from what it marshalls to: JSON Type | Java Type object | LinkedHashMap
