❓ Как и где Spring ищет бины?

Spring ищет бины с помощью сканирования классов в указанных пакетах, используя аннотации (@Component, @Service, @Repository, @Controller и кастомные с @Component внутри).

Сканирование начинается с пакета, переданного в @ComponentScan или (по умолчанию) из того, где находится @SpringBootApplication (которая включает @ComponentScan).

Если бин не помечен аннотацией, его можно зарегистрировать вручную через @Bean в @Configuration-классе, BeanDefinitionRegistry или XML-конфиг.

How Does Telegram Make Money?

Telegram is a free app and runs on donations. According to a blog on the telegram: We believe in fast and secure messaging that is also 100% free. Pavel Durov, who shares our vision, supplied Telegram with a generous donation, so we have quite enough money for the time being. If Telegram runs out, we will introduce non-essential paid options to support the infrastructure and finance developer salaries. But making profits will never be an end-goal for Telegram.

Telegram hopes to raise $1bn with a convertible bond private placement

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
