Apache Camel: Cannot deserialize instance of out of START_ARRAY token

I go over http to the rest service, which returns this json:

[
  {
    "name":"D",
    "surname":"D"
  },
  {
    "name":"T",
    "surname":"T"
  }
]

In order to change it to an object when called, I created this structure:

@Data
public class User {
    String name;
    String surname;
}

I tried to take it like this:

public static void addDirectRestRoute(RouteBuilder routeBuilder, String directEndpointName, String url, String a) {
    routeBuilder.from("direct://" + directEndpointName)
        .setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
        .setHeader(Exchange.HTTP_METHOD).constant(HttpMethod.GET)
        //.setHeader(Exchange.HTTP_QUERY, simple("?id=1"))
        .to(url)
        .unmarshal().json(JsonLibrary.Jackson, User.class);
        //.unmarshal(new JacksonDataFormat(User.class));
}

Get an error. I tried this:

@Data
public class User {
    List<U> u;

    @Data
    public class U {
        String name;
        String surname;
    }
}

I still get an error. Here's the error:

What is wrong with my data structure?
