    • resources

      ResourceRoute resources(Class<?> cls)

      Builds the necessary mappings to treat the given class as a REST endpoint.

      For example given a class called BookController the following routes will be produced:

      
     GET "/book"
     GET "/book{/id}"
     POST "/book"
     PUT "/book{/id}"

      cls - The class
      Returns:
      The ResourceRoute
