[V] $route
const $route: RouteDecorator;
@route
defines the relative route URI for the target operation
The first argument should be a URI fragment that may contain one or more path parameter fields.
If the namespace or interface that contains the operation is also marked with a @route
decorator,
it will be used as a prefix to the route URI of the operation.
@route
can only be applied to operations, namespaces, and interfaces.
