❓ Чем ApplicationContext отличается от BeanFactory?

🔹 BeanFactory — минимальное ядро DI контейнера. Способен:

— Загружать и управлять бинами.
— Создавать их по мере необходимости (лениво).
— Делать DI и обращаться по имени/типу.

🔹 ApplicationContext = BeanFactory + плюшки:

— Поддержка i18n (MessageSource).
— Поддержка событий (ApplicationEventPublisher).
— Поддержка автоматической загрузки бинов (@ComponentScan, @Configuration, @Autowired, @Value и др.).
— Чтение из аннотированных конфигураций (@Bean, @Component, и т.д.).
— Интеграция с Spring AOP.
— Расширенный SPI — Environment, ResourceLoader, ApplicationContextAware и пр.

What is Telegram?

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.

To pay the bills, Mr. Durov is issuing investors $1 billion to $1.5 billion of company debt, with the promise of discounted equity if the company eventually goes public, the people briefed on the plans said. He has also announced plans to start selling ads in public Telegram channels as soon as later this year, as well as offering other premium services for businesses and users.
