Spring MVC: where can i get line-by-line explanation of the way Spring MVC process HTTP request?

Dispatcher servlet invokes a handler (a controller) based on handler mappings and then the matching controller delegates a service object to perform business logic and then returns back the created model to dispatcher servlet and then dispatcher servlet decides which view to pass model to ... blah blah. my question is whether there is any web page or book that explain about all these things. for example, what method does dispatcher servlet invoke on handler adaptor in order to invoke the matching controller. and etc. Any web page would be awesome.
