DTO mapping

[Clashsoft]

Add a new annotation called @DTO for reflective class building that automatically maps classes to DTOs.

The annotation should have three parameters:

• Class model (required) - the GenModel class that is used as a base
• String[] omit (optional, default {}) - the properties that should be omitted. Ignored if empty or pick is present.
• String[] pick (optional, default {}) - the properties that should be included. Ignored if empty.

Generated DTO classes automatically use the POJO property style. Associations are mapped to String or List/Set<String> fields that may hold the ID of the target objects. In the future, we could add an @ID annotation that could override this behaviour to use another ID type like int, long, UUID, etc..

Example

org/example/model/GenModel:

class GenModel {
  class User {
    String id;
    @Link("user") Address address;
  }

  class Address {
    String id;
    String city;
    String street;
    ...
    @Link("address") User user;
  }

  ...
}

org/example/dto/GenDtos:

class GenDtos {
  @DTO(model = GenModel.User.class, omit = "id")
  class UserDto {
  }

  @DTO(model = GenModel.Address.class, pick = {"id", "street"})
  class AddressDto {
  }

  ...
}
