PHP-DI注射子不在设置方法上注射

Question

我在使用ContainerBuilder配置容器时具有设置依赖关系和定义，然后对其进行编译以获取实际的Container，但是每当我尝试注入依赖项时，它们总是倾向于忽略它们。

我是否错过了injectOn()方法的概念，还是我在这里做错了什么（$this->translator仍然没有分配）？我尝试过不同的方法，既可以实例化类并将对象添加到ContainerBuilder，并将其作为DIobject()定义传递，均为相同的结果。

<?php
include "../vendor/autoload.php";
class Translator
{}
class TextHandle
{
    protected $translator;
    public function setTranslator (Translator $translator)
    {
        $this->translator = $translator;
    }
    public function test ()
    {
        var_dump($this->translator);
    }
}
class TestCase
{
    protected $translator;
    public function __construct (Translator $translator)
    {
        $this->translator = $translator;
    }
}
// Setup container
$containerBuilder = new DIContainerBuilder();
$containerBuilder->addDefinitions([
    Translator::class => DIobject(),
]);
$container = $containerBuilder->build();
// Create object and inject
$textHandle = new TextHandle();
$container->injectOn($textHandle);
// Test injection, fails
$textHandle->test(); // NULL
// Test access, works
$translator = $container->get(Translator::class);
var_dump($translator); // object(Translator)#18 (0) {}
// Try having the container instantiate
$textHandle = $container->make(TextHandle::class);
$textHandle->test(); // Null
// Try object with constructor, works
$testCase = $container->make(TestCase::class);
var_dump($testCase); // Translator is set

根据文档，php-di不会通过setters进行自动化。

您应该添加TextHandle类的定义，并通过设置器将其配置为Translator：

$containerBuilder->addDefinitions([
    TextHandle::class => DIobject()->method('setTranslator', DIget(Translator::class))
]);
