As shown through the post linked in the comments, you are possibly missing some SLF4J dependencies. Another possibility, however, is that your dependencies actually have different versions of SLF4J, but since only one can be used there is a clash. See this SO post as well.

I would recommend explicitly using spring-boot-starter-log4j2 since you are using spring boot and going from there.
