I tried Spring Initializr. I made the mistake of picking human-friendly Freemarker templates instead of the XML abomination that is Thymeleaf, and things went to hell. And can you show the nice official documentation? All my searches back then pointed me only at blogs and stuff. All of them full of outdated advice — for example, the version I started with was one of the first to change the default file extension for Freemarker from `.ftl` to `.ftlh` for some invalid reason, but none of the online blogs were updated for it, I found out after a few hours of trying out random things when I stumbled upon the change log for that release. (The reason was allegedly “security”, but what stops them from disabling the insecure features and keeping the extension?) Another thing that was woefully under-documented was the default security thing, it also took me forever to figure out how to get a login page showing and working.
