How to get the WebApplicationType of Springboot application at runtime?

Question

I have a library that I use in reactive and non-reactive spring-boot applications. How can I within my library find out at runtime whether the application is REACTIVE or SERVLET?

You can use Java decompiler, such as

• http://www.javadecompilers.com/

• http://java-decompiler.github.io/

You will see something like this

If you see these classes like https://projectreactor.io/docs/core/release/api/ then, it is Spring Boot Reactor project, and vice versace.
