SPRINGMVC Overall architecture

Summarize:

1, the user initiates the request to the front-end controller (dispatchservlet);

2, the front controller does not have the ability to deal with business logic, need to find specific Model object processing (Handler), to the processor mapper to find Handler objects;

3, handlermapping return to the execution chain, including 2 parts of the content

A) Handler object

b) Interceptor Array (list)

4, the front controller through the adapter packaging after the execution of handler objects;

5. Handling Business logic

6, Handler processing business logic, return the Modelandview object, where view is the view name, not the real view object;

7, return the Modelandview to the front controller;

8, the front-end controller through the view name to the view parser to find the view;

9. The view parser returns the Real View object (views);

10, the front-end controller based on the model data and view objects, the view rendering;

11. Return to the rendered view (Html/json/xml)

12, to the user to generate a response
