通过 ServiceLocatorAwareInterface 注入 ServiceLocator 不起作用 [英] injecting ServiceLocator via ServiceLocatorAwareInterface doesnt work

问题描述

我读到实现:ServiceLocatorAwareInterface 会将 serviceLocator 注入同一个类.所以我得到了这个:

i read that implementing: ServiceLocatorAwareInterface will inject the serviceLocator to the same class. So I got this:

Class MyModel implements ServiceLocatorAwareInterface {


    protected $serviceLocator;


    public function setServiceLocator(ServiceLocatorInterface $serviceLocator)
    {
        $this->serviceLocator = $serviceLocator;
    }


    public function getServiceLocator()
    {
        return $this->serviceLocator;
    }

}

但是 $this->serviceLocator 总是 NULL

But $this->serviceLocator is always NULL

我还需要做更多吗?

推荐答案

您必须在服务配置中注册您的模型并使用服务管理器检索它.下面是一个例子:

You have to register your model in Service Config and retrieve it using service manager. Here is an example:

/* Module.php */
public function getServiceConfig() {
    return array(
        'invokables' => array(
            'my_model' => 'Application\Model\MyModel'
        )
    );
}

/* IndexController.php */
public function indexAction() {
    $model = $this->getServiceLocator()->get('my_model');
    $sl = $model->getServiceLocator(); // returns ServiceLocator
}
