Json到Java中的对象（Gson）

Question

I'm trying to create objects with this JSON:

{
"data": {
  "Prueba1": {
     "id": 266,
     "title": "Prueba1",
     "name": "Prueba1",
     "key": "Prueba1",
     "lore": "Prueba1"
  },
  "Prueba2": {
     "id": 111,
     "title": "Prueba2",
     "name": "Prueba2",
     "key": "Prueba2",
     "lore": "Prueba2"
  }
 },
"type": "prueba",
"version": "1.0"
}

The problem is that Gson is giving me the object 'data' but I can't not conver it to an array of objects.

My actual code is:

    JsonParser parser = new JsonParser();
    FileReader fr = new FileReader("route to archive json");
    JsonElement datos = parser.parse(fr);
    JsonElement heroes = datos.getAsJsonObject().get("data");

   final Gson gson = new Gson();
    final Type tipoListaEmpleados = new TypeToken<List<hero>>(){}.getType();
    final List<hero> hero = gson.fromJson(heroes, tipoListaEmpleados);

    System.out.println(hero.get(2));

But it's throwing error:

Expected BEGIN_ARRAY but was BEGIN_OBJECT at path $

Any tip about the problem would be appreciated.

PS: I understand that is giving all object, but I don't get the point of why is this happening, please help!!

EDIT: I'm working with an external API, that gives me that result, so I can't change the rest response, I need to convert to objects without adding []

EDIT2: Hero class looks like a single POJO :

public class hero
{
public int id;
public String title;
public String name;
public String key;
public String lore;
//constructor getters and setters
}

Your JSON doesn't actually have a JSON Array in it. Try this...although this might not be the exact structure you're looking for.

{
    "data": [{
        "Prueba1": {
            "id": 266,
            "title": "Prueba1",
            "name": "Prueba1",
            "key": "Prueba1",
            "lore": "Prueba1"
        },
        "Prueba2": {
            "id": 111,
            "title": "Prueba2",
            "name": "Prueba2",
            "key": "Prueba2",
            "lore": "Prueba2"
        }
    }],
    "type": "prueba",
    "version": "1.0"
}
