Мобильная версияПримечание: Я тестировал с Maven 4.0.0-rc-4. И я следил за https://maven.apache.org/maven-di.html, который говорит:
maven di-это структура инъекции зависимости Maven, которая вводится в Maven 4. Это успешно для Plectus iocd ioc. 330 /eclipse sisu (используется в Maven 3) в Maven. < /P>

Однако, если я переключаю часть @Inject Использование @Inject везде
