> The HTTP method parameter has no default. So, if we don’t specify a value, it will be assigned to any HTTP request.
> RequestMapping can narrow the mapping further by specifying a request header.
> We can assign a request based on the address it accepts via the @RequestMapping headers
> Parts of the mapping URI can be bound to variables via the PathVariable annotation.
> If the method parameter name matches the path variable name exactly, this can be simplified by using PathVariable without a value.
> MultiplePathVariable: A more complex URI may need to map multiple parts of a URI to multiple values.
> @RequestMapping allows easy assignment of URL parameters using the @RequestParam annotation.
