+#### Упражнение №2
+- Изучить классы ничего в них не меняя:
+ - CustomBeanFactoryPostProcessor
+ - CustomBeanPostProcessor
+ - CustomLifeCycleBean
+- Запуститить приложение
+- Изучить распечатанный жизненный цикл
+
+
+#### Упражнение №3
+- В application.yml выставить spring.shell.interactive.enabled в true
+- Запуститить приложение командой "cfn" или "call-favorite-number"
+- Запомнить результат
+- В CustomBeanFactoryPostProcessor раскомментировать блок кода
+- Запуститить приложение командой "cfn" или "call-favorite-number"
+- Что изменилось?
+- В CustomBeanPostProcessor раскомментировать строку
+- Запуститить приложение командой "cfn" или "call-favorite-number"
+- Что изменилось теперь? Круто, да?
