Autoconfiguration replace imported services - php

Question

When I import services in the main configuration:
imports:
- { resource: services/attribute_loaders.yaml }
The services in the included file will be replaced with an autoconfigured version, so I've missed all my configured tags:
services:
App\Infrastructure\Bridge\Doctrine\EventListener\AttributeLoader\OrderAttributeLoader:
autowire: true
tags:
- name: 'doctrine_mongodb.odm.event_listener'
entity: 'App\Infrastructure\Bridge\Doctrine\EventListener\AttributeLoader\OrderAttributeLoader'
event: 'postLoad'
As a workaround, I've excluded my service from autoconfigure.
Is there any way to decompose services into several files?

That's exactly how you do it.
If you are going to use multiple files to configure your services, you simply can't define the same service twice.
Your definitions need to be specific enough so they do not overlap.
If you are going to use broad resource settings, you will need to add all the corresponding excludes so services defined in different files are not defined before it's time:
services:
App\:
resource: '../src/*'
exclude:
- '../src/Infrastructure/Symfony/DependencyInjection'
- '../src/Infrastructure/Symfony/Kernel.php'
- '../src/Tests'
- '../src/Messenger'
Services on src/Messenger, that belong to the App\Messenger namespace, can be defined independently on a different file:
E.g. something like this:
# messenger_services.yaml
services:
_defaults:
autowire: true # Automatically injects dependencies in your services.
autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
public: false
App\Messenger\CommandHandler\:
resource: '../../src/Messenger/CommandHandler/*'
tags:
- {name: 'messenger.message_handler', bus: command.bus}
App\Messenger\EventHandler\:
resource: '../../src/Application/EventHandler/*'
tags:
- {name: 'messenger.message_handler', bus: event.bus}
