This guide walks through creating custom Spring MVC core components—including DispatcherServlet, HandlerMapping, HandlerAdapter, and ViewResolver—using annotations and Java code to gain full control over request handling, parameter resolution, and response rendering in backend development.
This article explains how Spring’s DispatcherServlet processes incoming HTTP requests by locating the appropriate HandlerMapping, selecting a HandlerAdapter, invoking pre‑ and post‑handle interceptors, executing the controller method, and finally rendering the response or handling errors, with detailed code examples.
This article walks through the complete request processing flow of SpringBoot 2.2.6's DispatcherServlet, detailing how it obtains the HandlerExecutionChain, resolves the appropriate HandlerMethod via RequestMappingHandlerMapping, selects a HandlerAdapter, executes interceptors, invokes the controller method, and finally processes the response with converters and advice.
This article walks through the Spring MVC request handling pipeline step by step, explaining how DispatcherServlet sets attributes, resolves handlers, invokes handler adapters, runs pre‑ and post‑interceptors, creates ModelAndView, resolves the view and finally renders the response, with code examples from the original framework.
