I'm currently dealing with a framework where I've got to define data models here, register them with dependency injection over there, use them in an API controller a third place, register the routes somewhere else, and touch three or four different UI components, every time I make a small change. It's not Java, but it feels very Spring-inspired. The difference is stark when I have the lean, more-or-less functional core business logic library sitting beside this baroque stringly-typed reflected 7-bean salad of a web application shell.
