method for the more general case where no name value is given. You could make the method handle both cases explicitly like this @RequestMapping(value = {"/gif", "/gif/{name}"})
, and inside the method, check if name == null
, then do something based on that.
Take a look at the explanation given at this link https://www.baeldung.com/spring-optional-path-variables
