Spring MVC

[J Mohandos]

I am referring the following tutorial

http://www.tutorialspoint.com/spring/spring_web_mvc_framework.htm

Quoting from above link:

After receiving an HTTP request, DispatcherServlet consults the HandlerMapping to call the appropriate Controller.

By HandlerMapping I am assuming they are talking about web.xml. If I use the link mentioned above I see no connection how the controller is called, as in web.xml the org.springframework.web.servlet.DispatcherServlet class is mapped to HelloWeb and the name of the controller is HelloController. I am unable to understand how the controller gets called. What am I missing?

THe HandlerMapping gets constructed during load time by Spring. It does that by looking at the annottations. SO, when you do

@Controller
@RequestMapping("/hello")
public class HelloController{

You are basically adding an entry into the Handler mapping that tells it that /hello is mapped to HelloController

The servlet name in web.xml is given as HelloWeb. To what does it link?Or in other words where is it used?

[Prasad Krishnegowda]

The configuration file has to be <servletname>-servlet.xml
