In the next lecture, we will move from servlet to netty? WebFlux? https://docs.spring.io/spring-boot/docs/2.1.10.RELEASE/reference/html/howto-embedded-web-servers.html#howto-configure-webserver Ah;; I want to know how to convert from servlet to reactive stack. And I also want to know how to add spring beans dynamically. Even if I read a file, the empty memory is dynamically called? Thank you. Everyone, exercise and stay healthy~*
