Symfony 2 注入记录器服务

Symfony 2 Injecting logger service

我在 symfony 2 中使用记录器服务时遇到一个奇怪的问题:

将记录器注入服务时,我收到类型错误,因为 LoggerInterface 预期但 Symfony\Bridge\Monolog\Logger 给定。

此外,如果我尝试注入自定义记录器,我会因为未定义的服务而出错。

这是我的代码:

confiy.yml

monolog:
channels: ['payment']
handlers:
    paymentlog:
        type: stream
        path: "%kernel.logs_dir%/payment.log"
        level: debug
        channels: [payment]

service.yml

#payment_services
  payment.gateway_payments:
    class: AppBundle\Service\paymentService
    arguments: ["@service_container", "@doctrine.orm.entity_manager", "@logger"]

服务:

<?php

  namespace AppBundle\Service;

  use Symfony\Component\DependencyInjection\ContainerInterface;
  use Doctrine\ORM\EntityManager;
  use Symfony\Component\HttpKernel\Log\LoggerInterface;

  class paymentService {

    private $container;
    private $em;
    private $logger;

    public function __construct(ContainerInterface $container, EntityManager $em, LoggerInterface $logger){
    $this->container = $container;
    $this->em = $em;
    $this->logger = $logger;
}

同时使用 @monolog.logger.paymentlog 注入记录器给我一个错误 "undefinded service"

谁能告诉我哪里错了?

非常感谢。

试试这个:

use Monolog\Logger;

而不是这个:

use Symfony\Component\HttpKernel\Log\LoggerInterface;

在此之后;

public function __construct(ContainerInterface $container, EntityManager $em, Logger $logger){

插入这个:

public function __construct(ContainerInterface $container, EntityManager $em, LoggerInterface $logger){
