In situation when we create FeignClient in this way: @FeignClient(url = "https://localhost/", path = "api/v2") We will get an error because of adding '/' in the beginning of the path in FeignClientsRegistrar.getPath, result will: https://localhost//api/v2 To escape this situation we need to delete '/' at the end of url in FeignClientsRegistrar.getUrl
