Spring is very good software, and basically and object oriented language will need to use stuff like it after enterprises throw their stack of requirements at it for 20+ years and following 20 years of technology evolution. Yes its been tied to many java architectural fashion boondoggles of the past (XML config madness, XML namespace magic, overly heavyweight serverside HTML rendering, JSP tag madness, software patterns) but I still turn to it for basic code structuring in any JVM app. Boot is pretty good ... until its not. If you are doing garden variety web services it gets you up and running fairly well. If you need to do anything fancy with routing or raw data in the html request/response, then it is not. And Spring is now so synonymous with Spring Boot that it kind of isn't a good thing. Spring also isn't a pure open source project, it has a company trying to constantly steer it to revenue production, but as those types of entities go, stewardship has been decent. Normally things like that have about four or five years of trying to use open source for market expansion before impatience/greed/frustration sits in and they go for the closed source grab (see: Hashicorp recently). 20 years is a remarkable run for something like that.
