What is the Dispatcherservlet function in Spring?

Question

Answer 1

The work of DispatcherServlet is to take a requested URI and find the right combination of the handler (usually methods in the controller classes) and views (usually Jsps) that match to the form of the page or resource supposed to be found in that location.

I may have :

• an archive /WEB-INF/jsp/pages/Home.jsp.

• a method in the class

  @RequestMapping(value="/pages/Home.html")
  private ModelMap buildHome() {
      return somestuff;
  }
  

Dispatcher Servlet is the piece that "knows" to call the method when the browser requests the page, combines the results with the JSP file and generates an HTML document.
