-#### Declare DTO
-
-```cpp
-class UserDto : public oatpp::data::mapping::type::Object {
-
-  DTO_INIT(UserDto, Object)
-
-  DTO_FIELD(Int64, id);
-  DTO_FIELD(String, name);
-
-};
-```

-#### Serialize DTO Using ObjectMapper
-
-```cpp
-using namespace oatpp::parser::json::mapping;
-
-auto user = UserDto::createShared();
-user->id = 1;
-user->name = "Ivan";
-
-auto objectMapper = ObjectMapper::createShared();
-auto json = objectMapper->writeToString(user);
