How to extract the URL parameters using Spring DSL?

How to extract the URL parameters using Spring DSL?

For example:
http://localhost:8080/service/inv/US/1000/123456/1K

from the above URL I need to extract the US,1000,123456 and 1K values.
These parameters I have to attach dynamically to the other service URL while
route.
Like below
http://test.com:9089/example/service/{country}/{item#}/{store#}/{size}

Thanks,
Guru
