PHP-DI没有为“接口名称”找到条目或类

Question

所以，我第一次尝试设置php，但是我在构建器上遇到了一些麻烦。我不断地发现错误：

Uncaught exception 'DI\NotFoundException' with message 'No entry or class found for 'IConnection'' in /path/PHPDiContainer.php'

我的容器设置哪里出错了？

<?php 
require_once 'vendor/autoload.php';

use repositories\Connection;
use irepositories\IConnection;
use DI\ContainerBuilder;

$container = DI\ContainerBuilder::buildDevContainer();
$builder = new DI\containerBuilder();
$builder->addDefinitions([
    IConnection::class => DI\object(Connection::class)
]);
$container = $builder->build();
$connection = $container->get('Connection');
... Code to show it works.
?>

IConnection::class返回完全限定的类名：irepositories\IConnection。因此，您将在PHP中以该名称注册连接。

如果您想得到它，Connection将不匹配任何东西。你得做：

$connection = $container->get('irepositories\IConnection');
// or
$connection = $container->get(IConnection::class);
