The negativism towards has two main points: First, that Spring it's bloated. Spring now has a wide extension of modules that you may or may not need. Most of those modules won't even be added in your classpath unless specified in your pom.xml or build.gradle file. Very simple projects won't need the vast majority of the full Spring power. Second, that a Spring project takes too much time to launch the web app (Compared against other frameworks doing the same task). Part of the reason it takes too much time to start comes from how the engine inflates the beans and injects it. On that same topic, other frameworks such as Micronaut are more lightweight because they don't bloat the framework as much as spring, thus the launch time is shorter. Also take into account that Java developers adore complexity in code structure so that also affects launch time. Are you going to regret going with Spring? No, there is a lot of support from the community, if you have any issue you will find help in reddit and stackoverflow. It's a really mature framework. However it's not the only option. There are other frameworks that could be a better choice for your use cases.
