You probably won't regret it, Spring is a solid framework. But the issue with Spring in my experience is that it has constant breaking upgrades with various dependencies But this is more of an enterprise issue. Upgrade breaks a dependency, fixing that dependency will break another dependency, etc. While some people say Spring Boot is convention over configuration, I don't really buy that, the configuration is done via annotations which is still configuration. My other gripe with Spring is that despite it all being annotations, when it breaks it can be opaque about why it broke, or why it didn't bind something.
