Feature: #82869 - Replace @inject with @TYPO3\CMS\Extbase\Annotation\Inject

Description

As a successor to the @inject annotation, the doctrine annotation @TYPO3\CMS\Extbase\Annotation\Inject has been introduced.

Example:

/**
 * @TYPO3\CMS\Extbase\Annotation\Inject
 * @var Foo
 */
public $property;

Doctrine annotations are actual defined classes, therefore you can also use the annotation with a use statement.

Example:

use TYPO3\CMS\Extbase\Annotation\Inject;

/**
 * @Inject
 * @var Foo
 */
public $property;

Used annotations can also be aliased which the core will most likely be using a lot in the future.

Example:

use TYPO3\CMS\Extbase\Annotation as Extbase;

/**
 * @Extbase\Inject
 * @var Foo
 */
public $property;

Impact

In 9.x there is no actual impact. Both the simple @inject and @TYPO3\CMS\Extbase\Annotation\Inject can be used side by side. However, @inject is deprecated in 9.x and will be removed in version 10.
