- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
有人知道为什么会这样吗?
据我所知,子类方法的声明方式与父类方法相同。
谢谢!

最佳答案
答案在于导入的命名空间。在 Kernel
的文件中,有这个 use 子句:
use Symfony\Component\DependencyInjection\Loader\LoaderInterface;
因此将 LoaderInterface
与完全命名空间的类 Symfony\Component\DependencyInjection\Loader\LoaderInterface
联系起来。
基本上制作签名:
public function registerContainerConfiguration(Symfony\Component\DependencyInjection\Loader\LoaderInterface $loader);
在您的类(class)中,您不会导入该命名空间。因此 PHP 默认假定该类位于您的命名空间中(因为没有导入的命名空间具有该接口(interface)名称)。
所以你的签名是(因为你没有声明命名空间):
public function registerContainerConfiguration(\LoaderInterface $loader);
因此,要使它们匹配,只需将 use
行添加到文件顶部即可:
use Symfony\Component\DependencyInjection\Loader\LoaderInterface;
