本文详细阐述了SpringMVC框架中的请求处理流程。从浏览器输入URL开始，介绍请求如何到达DispatcherServlet，再到控制器处理请求并返回视图名，直至最终页面呈现到用户面前的过程。

The Spring MVC request flow in short:

When we enter a URL in the browser, the request comes to the dispatcher servlet. The dispatcher servlet then acts as a centralized entry point to the web application.
The dispatcher servlet determines a suitable controller that is capable of handling the request and dispatching this request to the controller.
The controller method updates objects in the model and returns the logical view name and updated model to the dispatcher servlet.
The dispatcher servlet consults with the view resolver to determine which view to render and passes the model data to that view.
The view furnishes the dynamic values in the web page using the model data, renders the final web page, and returns this web page to the dispatcher servlet.
At the end, the dispatcher servlet returns the final, rendered page as a response to the browser.
