使用gson序列化具有泛型类型的类？

public class Response<T> {
    private int code;
    private String message;
    private T data;

    // 省略构造方法和getter/setter方法
}

Gson gson = new Gson();

Type type = new TypeToken<Response<User>>(){}.getType();

Response<User> response = new Response<>();
response.setCode(200);
response.setMessage("Success");
response.setData(new User("John", "Doe"));

String json = gson.toJson(response, type);

String json = "{\"code\":200,\"message\":\"Success\",\"data\":{\"name\":\"John\",\"lastName\":\"Doe\"}}";

Type type = new TypeToken<Response<User>>(){}.getType();

Response<User> response = gson.fromJson(json, type);
