This solution worked for me. I needed to create urls for a REST client dynamically so I created this method, so you just have to pass the restURL like this

/customer/{0}/user/{1}/order

and add as many params as you need:

public String createURL (String restURL, Object ... params) {       
    return new MessageFormat(restURL).format(params);
}

You just have to call this method like this:

createURL("/customer/{0}/user/{1}/order", 123, 321);

The output

"/customer/123/user/321/order"
