Spring MVC Framework Structure

  

Spring MVC is designed around Dispatcherservlet, and Dispatcherservlet distributes various requests to handlers. Handlers are based on @controller and @requestmapping annotations by default.

Spring MVC's design principle is the open and closed principle, so some of the methods in the spring MVC core class are final.

code example

  

// 1. Turn the Usercontroller into a handler // 2. Specify the URL of the controller map  Public class Usercontroller {    //  3. URL of the processing method corresponding to URLpublic      String at 2 Register () {        return//  4. Return logical view name     }}
