First, @RequestMapping IntroductionUse @RequestMapping in spring MVC to map a request, that is, to specify which URL requests the controller can handle, which is equivalent to configuring the servlet in Web. xmlThe mapping effect is consistent. Let's look at the source code for the Requestmapping annotation class first:@Target ({elementtype.method, elementtype.type}) @Retention (retentionpolicy.runtime) @Do

1. OverviewThe following diagram is the overall flow of Spring MVC processing requests, where front controller refers to the Dispatcherservlet class.1. All client requests are sent to Dispatcherservlet and processed by Dispacherservlet.2.DispacherServlet distributes the request to different controller classes, and the controller class handles the corresponding re

Spring mvc-File Upload When uploading a file, we need to use the file upload parser. In fact, it is no stranger. It is just an extension of httpServletRequest, so that it can better process file uploads. The extension interface name is: org. springframework. web. multipart. multipartHttpServletRequest First, let's take a look at the underlying architecture of the

recommend a series of blog to learn spring, this article is also read one of the blog wrote. poke here . The Spring Web MVC Framework is a request-driven web framework and is also designed using a front-end controller pattern, distributed to the appropriate page controller (action/processor) for processing according to the request mapping rules.

Based on the returned Modelandview, select a suitable viewresolver (must be a viewresolver already registered in the spring container) to return to Dispatcherservlet;7.
