Spring is the framework and mvc is the design pattern. , m stands for model; ; V stands for opinion; ; C stands for controller. Literally, it can be seen that M refers to the model, and generally refers to Tao and service. Views represent displays. General c values such as page eg: JSP and html ftl are controllers, such as struts and action and controller in springMVC. Strictly speaking, springMVC refers to the front-end controller, that is, the controller that the client has to go through springMVC every time it interacts with the server.
