Servlet url mapping for front controller pattern [duplicate]

Question

I am trying to learn spring MVC framework. Dispatcher servlet is suppose to handle all the incoming requests and we achieve that with following configuration :

<servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

My question is how / is different from /*. When we return the view name, we usually prefix / before the view name like /WEB-INF, so will that request also go through DispatcherServlet. If not why?

Have a look here stackoverflow.com/questions/13843294/…

In a JAVA EE web application, there are 3 parts to URL mappings:

Context path (root of your URL)
Servlet path (pattern that activated your component)
Info path (The trailing path)

E.g. Dispatcher mapped to "/myservlet/", with "root" context

GET /root/myservlet/info

/root context path
/myservlet servlet path
/info info path

"/" and "/*" will match any token afterwards, but "/" will only match if no explicit mapping for the path is provided (in this case, if there is a servlet mapping for /myservlet/info).

"/" becomes the container default fallback for the path.

"/*" overrides everything under the path. As mentioned here, this is great for Filter mappings.
