What features from Django are you missing and in which frameworks? Comparing Django(admittedly, from few years ago when I worked with it) with Spring, I'd say the latter is more feature-rich and way more customizable because of its modular design. Unfortunately, it's also much more complex and setting up a new project properly with all can be overwhelming so if you want to play around with it I'd recommend to start with JHipster template - it generates a React/Angular SPA with backend in Spring.
