Get the Public URL from a Springboot Controller

[ikoyski]

I was wondering if anyone can help me on this one. When i start the the app, the public/preview URL changes from time to time.. Now its http://node17.codenvy.io:44082/ and later on it will change so its dynamic.

How can i get the current public/preview base URL from code? E.g. ${baseURL}

String successUrl = ${baseURL} + "/result?flag=Successful";
String failUrl = ${baseURL} + "/result?flag=Unsuccessful";
String cancelUrl = ${baseURL} + "/result?flag=Canceled";
