I would go so far as to say the rise of Rails and the downfall of J2EE being concurrent was not entirely accidental. I have/had no particular affiliation for Rails, but it demonstrated how to write simple, opinionated backend code, and that inspired a flurry of Java/JVM web frameworks that tried to follow a similar pattern and eventually gave us libraries like DropWizard, Javalin, SparkJava, even Spring Boot to some extent.
