Magically inject dependencies into services

magic-injection-bundle

, _(*1)

This Symfony2 bundle provides a way to magically inject dependencies into your services. The dependencies will not be available in the constructor. To use it, you need to complete the following steps:, _(*2)

1. Add the tag magic_injection.injectable_service to the service you wish to inject. The tag takes an optional argument called type, which you can use to group injectable services.
2. Add the tag magic_injection.injection_target to the service which should receive the injected services.
3. Finally, annotate properties with the MagicInjection annotation, which will take an optional type argument that refers to a group of injectable services.

Example usage

• services.yml, _(*3)

  services:
  
  service.that.will.be.injected:
    class: Service\MyServiceA
    tags:
      - { name: magic_injection.injectable_service, type: my_services }
  
  service.that.has.a.dependency:
    class: Service\MyServiceB
    tags:
      - { name: magic_injection.injection_target }
  

• MyServiceB.php, _(*4)

  class MyServiceB
  {
  /**
   * @MagicInjection(type="my_services")
   * @var \Service\MyServiceA
   */
  private $myServiceA;
  
  public function __construct()
  {
    assert($this->myServiceA === null);
  }
  
  public function foo()
  {
    $this->myServiceA->bar();
  }
  }
