I bet this is happening because in many enterprise applications you do not need high performance. Requirements to a service doing 1000 transactions a day are very different from requirements to a service doing HFT. Service per bounded context may be reasonable choice and Spring Boot/Spring Cloud may be adequate solution for it.
Minecraft builds their servers using Micronaut! It's such a breath of fresh air compared to spring.
I've only ever had to debug spring DI once, I'll admit it usually works. But when it doesn't..... All those proxy objects will drive you nuts!
It's a very clever solution really.. And that's the problem! You don't want to build your servers on a clever foundation, you want a simple one!
That's kind of where I stand on this too... though I'm more fond of a lot of C# than Java, I find that it's the developer ecosystem and work environments themselves that exist on so many piles of abstractions and patterns that it's often hard to even grasp the meat of what's being done over the abstractions themselves.
I've trended towards feature oriented hierarchies over type of thing hierarchies as I find they tend to be simpler, easier to replace over time and often much easier to maintain than separating DAL/BLL/SVC/VM/M/V layers etc. I really don't mind if my endpoint file sits next to my database access file, next to my validation file along with the test files for all of them in a single directory for a given feature. The feature is the concern, not the fact that you have a web endpoint, or need to talk to a database.
They're also easier to manage in a monolith and break apart as needed without having to replicate the jungle for want of a banana.
