the specific process steps for the core architecture are as follows:1, the first user sends the request-->dispatcherservlet, the Front controller receives the request not to carry on the processing, but entrusts to the other parser to carry onprocessing, as a unified access point, the global process control;2,dispatcherservlet-->handlermapping, handlermapping will map the request to a Handlerexecutionchain object (containing aHandler Processor (page Controller) object, multiple Handlerinterceptor Interceptors) object, this policy mode makes it easy to add a newmapping strategy;3,dispatcherservlet-->handleradapter,Handleradapter will wrap the processor as an adapter to support multiple types of processors,the application of adapter design mode, which makes it easy to support many types of processors;4,handleradapter--> Processor function processing method call,Handleradapter will be based on the results of the adaptation to call the real processor functionfunction processing, and returns a Modelandview object (containing model data, logical view name);5,modelandview logical View name ----Viewresolver, Viewresolver will parse the logical view name into a specific view, through this policyeasy to replace other view technologies;6,view--> rendering , the View will be based on the model data passed in to render, here the model is actually a map data structure, soIt is easy to support other view technologies;7, return control to Dispatcherservlet, by Dispatcherservlet return response to the user, to this end of a process.
