更新后我有这个弃用：

Since symfony/dependency-injection 5.1: The "Symfony\Component\DependencyInjection\ContainerInterface" autowiring alias is deprecated. Define it explicitly in your app if you want to keep using it. It is being referenced by the "App\Service\ImportService" service.

这是我的ImportService：

<?php

namespace App\Service;

use Symfony\Component\DependencyInjection\ContainerInterface;

class ImportService
{
    private $doctrine;
    private $em;

    public function __construct(ContainerInterface $container)
    {
        $this->doctrine = $container->get('doctrine'); //needed for database queries
        $this->em = $this->doctrine->getManager(); //needed for database queries
    }

    /** more methods here **/

}

那么我究竟如何使它明确呢？我用谷歌搜索了一下，我认为我必须以services.yml某种方式将它添加到我的文件中。但我不确定如何+我必须为每个服务类做这件事？

我刚刚在我的项目中发现了一些奇怪的东西。我正在使用 PHP7.3 并且我正在尝试将该array_column()函数与对象一起使用。

我正在使用一个命令来调用一个 symfony 项目中的服务 - 如果这很重要，但是我已经将我的代码简化为最重要的。

文章.php :

class Article {
    private $id;
    private $category;

    public function __construct()
    {
        $this->category = new ArrayCollection();
    }

    public function getCategory(): Collection
    {
        return $this->category;
    }

    public function addCategory(ArticleCategory $category): self
    {
        if (!$this->category->contains($category)) {
            $this->category[] = $category;
        }

        return $this;
    }

    public function removeCategory(ArticleCategory $category): self
    {
        if ($this->category->contains($category)) {
            $this->category->removeElement($category);
        }

        return $this;
    }
}
