Java doesn't have a widely adopted framework for kickstarting development like Ruby on Rails or Django Admin Panel. Actually .net core comes much closer with web apis and the default web projects you can build. Spring boot is pretty good, but has a much bigger learning curve than Django or Rails IMHO, there are several templating frameworks that might help you but none of them are "standard", I seem to remember using Thymeleaf for something a long while back.
