如何在Symfony中的另一个服务中注入服务? [英] How to inject a service in another service in Symfony?

问题描述

我正试图在另一个服务中使用日志记录服务，以便对该服务进行故障排除.

I am trying to use the logging service in another service in order to trouble shoot that service.

我的config.yml看起来像这样:

My config.yml looks like this:

services:
    userbundle_service:
        class:        Main\UserBundle\Controller\UserBundleService
        arguments: [@security.context]

    log_handler:
        class: %monolog.handler.stream.class%
        arguments: [ %kernel.logs_dir%/%kernel.environment%.jini.log ]


    logger:
        class: %monolog.logger.class%
        arguments: [ jini ]
        calls: [ [pushHandler, [@log_handler]] ]

这在控制器等中工作正常.但是，在其他服务中使用它时，我却没有表现出来.

This works fine in controllers etc. however I get no out put when I use it in other services.

有什么提示吗?

推荐答案

您将服务ID作为参数传递给服务的构造方法或设置方法.

You pass service id as argument to constructor or setter of a service.

假设您的其他服务是userbundle_service:

userbundle_service:
    class:        Main\UserBundle\Controller\UserBundleService
    arguments: [@security.context, @logger]

现在Logger传递给UserBundleService构造函数，前提是您已正确更新它，例如.

Now Logger is passed to UserBundleService constructor provided you properly update it, e.G.

protected $securityContext;
protected $logger;

public function __construct(SecurityContextInterface $securityContext, Logger $logger)
{
    $this->securityContext = $securityContext;
    $this->logger = $logger;
}
