A Long Spring: 19 Years of Living with Your Past Mistakes
summary
Spring MVC evolves from XML to annotation-based controllers to a functional DSL that reunites behavior and data, and the framework chooses bubble sort for media-type selection because media types form a partial order, not a comparator-friendly total order. HTTP clients move from a bloated RestTemplate (now rest template deprecated in Spring 7) to a staged RestClient/WebClient builder that prevents invalid state and fixes URI double-encoding by offering string and java.net.URI forms. A long-lived bug — the HTTP method enum->class change — finally allows nonstandard methods after a five-year struggle.
