服务感知包

创建具有依赖关系的服务可能会产生大量重复的元代码。例如

service:
    service_foo:
        class: Acme\DemoBundle\Service\Foo
        calls:
            - [setEntityManager, [@doctrine.orm.default_entity_manager]]
            - [setTranslator, [@translator]]
            
    service_bar:
        class: Acme\DemoBundle\Service\Bar
        calls:
            - [setTranslator, [@translator]]
            - [setValidator, [@validator]]
            
    service_zap:
        class: Acme\DemoBundle\Service\Zap
        calls:
            - [setEntityManager, [@doctrine.orm.default_entity_manager]]
            - [setTranslator, [@translator]]
            - [setValidator, [@validator]]

在类中

namespace Acme\DemoBundle\Service;

class Foo {
    private $entityManager;
    private $translator;
    
    public function setEntityManager($entityManager) {
        $this->entityManager = $entityManager;
    }
    
    public function setTranslator($translator) {
        $this->translator = $translator;
    }
}

namespace Acme\DemoBundle\Service;

class Bar {
    private $translator;
    private $validator;
    
    public function setTranslator($translator) {
        $this->translator = $translator;
    }
    
    public function setValidator($validator) {
        $this->validator = $validator;
    }
}

namespace Acme\DemoBundle\Service;

class Zap {
    private $entityManager;
    private $translator;
    private $validator;
    
    public function setEntityManager($entityManager) {
        $this->entityManager = $entityManager;
    }
    
    public function setTranslator($translator) {
        $this->translator = $translator;
    }
    
    public function setValidator($validator) {
        $this->validator = $validator;
    }
}

此包可以帮助您避免定义所有的setter调用和实现。它提供许多 *Aware 接口、抽象基类和特性。

如何使用

使用此包很简单，您只需要实现接口，并从 services.yml 中移除setter调用。

service:
    service_foo:
        class: Acme\DemoBundle\Service\Foo
            
    service_bar:
        class: Acme\DemoBundle\Service\Bar
            
    service_zap:
        class: Acme\DemoBundle\Service\Zap

在类中

namespace Acme\DemoBundle\Service;

use Bit3\Symfony\ServiceAwareBundle\Doctrine\DoctrineBundle\EntityManagerAwareInterface;
use Bit3\Symfony\ServiceAwareBundle\Doctrine\DoctrineBundle\EntityManagerAwareTrait;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Translator\TranslatorAwareInterface;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Translator\TranslatorAwareTrait;

class Foo implements EntityManagerAwareInterface, TranslatorAwareInterface {
    use EntityManagerAwareTrait;
    use TranslatorAwareTrait;
}

namespace Acme\DemoBundle\Service;

use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Translator\TranslatorAwareInterface;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Translator\TranslatorAwareTrait;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Validator\ValidatorAwareInterface;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Validator\ValidatorAwareTrait;

class Bar implements EntityManagerAwareInterface, TranslatorAwareInterface, ValidatorAwareInterface {
    use TranslatorAwareTrait;
    use ValidatorAwareTrait;
}

namespace Acme\DemoBundle\Service;

use Bit3\Symfony\ServiceAwareBundle\Doctrine\DoctrineBundle\EntityManagerAwareInterface;
use Bit3\Symfony\ServiceAwareBundle\Doctrine\DoctrineBundle\EntityManagerAwareTrait;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Translator\TranslatorAwareInterface;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Translator\TranslatorAwareTrait;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Validator\ValidatorAwareInterface;
use Bit3\Symfony\ServiceAwareBundle\Symfony\FrameworkBundle\Validator\ValidatorAwareTrait;

class Zap implements EntityManagerAwareInterface, TranslatorAwareInterface, ValidatorAwareInterface {
    use EntityManagerAwareTrait;
    use TranslatorAwareTrait;
    use ValidatorAwareTrait;
}

很简单，对吧？

定义服务感知接口

您可以在您的 app/config/config.yml 中定义自己的服务感知接口。

service_aware:
  services:
    acme_demo_bundle.services.service_foo:
      interface: "Acme\DemoBundle\Service\FooAwareInterface"
      method:    "setServiceFoo"
      service:   "acme_demo_bundle.service_foo"
