If you don t want any dependency on Spring s HATEOAS or javax   namespace  use ServletUriComponentsBuilder to get URI of current request   import org springframework web util UriComponentsBuilder   ServletUriComponentsBuilder fromCurrentRequest    ServletUriComponentsBuilder fromCurrentRequestUri

You may try adding an additional argument of type HttpServletRequest to the getUrlValue   method      RequestMapping value      produces    application json   public String getURLValue HttpServletRequest request       String test   request getRequestURI        return test

Add a parameter of type UriComponentsBuilder to your controller method  Spring will give you an instance that s preconfigured with the URI for the current request  and you can then customize it  such as by using MvcUriComponentsBuilder relativeTo to point at a different controller using the same prefix
