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 introduces the open‑source Spring framework for Java, explains the core concepts of Inversion of Control (IOC) and Aspect‑Oriented Programming (AOP), and walks through creating a Spring Boot web project with MVC layers, annotations, and a runnable example.
This article explains how to configure Spring Boot interceptors using both URL‑pattern matching and custom annotations, provides the necessary Java code for the interceptors and constant definitions, and shows how to register them in a @Configuration class for comprehensive request handling.
This article explains the role of Spring's DispatcherServlet, details its traditional web.xml configuration, walks through its request‑handling workflow, and shows how Spring Boot automatically configures and registers the servlet using concise code examples and annotations.
