We are facing issue related with making a path parameter optional.
original URL /expire/{token}
What we are trying to do is have the same service work for the URL's below.
1. /expire/{token}
2. /expire
Ex:- @Path("/expire/{token}")
We have already applied other solutions from SO,but no luck so far.

Required and Optional Parameters Note that path parameters must have required: true , because they are always required.
You can make a URI parameter as optional by adding a question mark (“?”) to the route parameter. If you make a route parameter as optional then you must specify a default value by using parameter = value for the method parameter.
Using an Optional Parameter Type. Here, Spring creates the Optional<Integer> instance, optionalArticleId, to hold the value of id. If id is present, optionalArticleId will wrap its value, otherwise, optionalArticleId will wrap a null value.
There are no optional parameters in Java. What you can do is overloading the functions and then passing default values.
What about adding another method annotated with only:
@Path("/expire")
And let this method pass a null value into the original method.

Logically, it doesn't seem to make sense to have it optional. Your URI should handle the type of request it's supposed to do. But, I came across a post to make the @PathParam to be optional with a small hack using regular expressions.

I would go with having separate endpoint method in Controller where it can pass the call to your services with optional parameter.
