Mapping Servlet URL for Controller Template
I am trying to learn the spring MVC framework. The dispatcher servlet must handle all incoming requests and we achieve this with the following configuration:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
My question is how / differs from / *. When we return the view name, we usually prefix / before the view name, for example / WEB -INF, so this request will also go through the DispatcherServlet. If not?

There are 3 parts of url mappings in JAVA EE web application:
- Context path (root of your url)
- Servlet path (template that activated your component)
- Information path (final path)
eg. The dispatcher associated with "/ myservlet /" with the context "root"
GET / root / myservlet / info
- / path to root content
- / myservlet path servlet
- / info info path
" / " and " / * " will match any token after that, but " / " will only match if an explicit mapping for path is provided (in this case, if there is a servlet mapping for / myservlet / info).
" / " becomes the default container for the path.
" / * " overrides everything in the path. As mentioned here , this is great for filter mappings.
