This is essentially the Java Servlet specification with JSPs (or if you don't like those, just bolt on Thymeleaf or one of the older templating languages).

Nearly all of these newer frameworks like Spring, Helidon, Quarkus, etc. just reuse the internal Sevrlet spec themselves. Otherwise, they're reinventing a TON of code that would be insane to do in order to deal with the general HTTP request / response cycle.
