I'm porting an application to a three-tier architecture (repository/service/controller). I want entities from Doctrine repositories to never be exposed to controllers but rather being mapped into DTOs which then get passed to controllers.

To map fields from entities to DTOs I'd like to use the new symfony/object-mapper but I'm encountering issues.

At the moment I have the fields in Doctrine entities exposed trough standard getters/setters

private string $my_field;

public function getMyField(): string
{
  return $this->my_field;
}

public function setMyField(string $my_field): static
{
  $this->my_field = $my_field;

  return $this;
}

but Symfony Object Mapper seems to totally ignore getters and setters so when I try to map entity's fields into their equivalent within DTO using the following statement

$dto = $mapper->map($entity, EntityName::class);

I always end up getting exceptions:

• If I name the field in the DTO $MyField I get a "the property MyField does not exists on EntityName"
• If I name the field in the DTO $my_field I get a "cannot access EntityName::$my_field private property" exception

In the official docs the only mention of getters/setters is in the last paragraph hinting at the possibility of configuring the mapper with a PropertyAccessorInterface object but little information is given on how to actually do that.

Can I make getters/setters recognizable to object mapper?
