Simple Java Client to parse OpenRouteService JSON responses using Jackson.
Parses JSON responses from OpenRouteService API V2 DirectionsServiceGET and DirectionsServicePOST endpoints.
Currently, this library is not available on Maven Central. To use with Gradle, build as a JAR using Intelli-J IDEA or other IDE, add the JAR to your project, and reference the location of the JAR in the dependencies section of your build.gradle file:
//Local packages
implementation files('../local_packages/ORS-J.jar')
Make a request for directions between (36.37,-94.2) and (36.39,-94.22) to a OpenRouteService. Sign up for an api key here.
//create connection object for routing server
HttpClient orsClient = HttpClient.newHttpClient();
DirectionsServicePOSTResult output = new DirectionsServicePOSTRequest(
"driving-car", //driver profile
36.37, //latitude a
-94.2, //longitude a
36.39, //latitude b
-94.22, //longitude b
0.6, //Maximum fraction of the route that alternatives may share with the optimal route.
2, //Target number of alternative routes to compute.
1.4, //Maximum factor by which route weight may diverge from the optimal route.
true, //include avg speed
true, //include elevation
max_speed, //max speed in mph
"mi", //distance units
orsClient, //HttpClient object
"https://api.openrouteservice.org/v2/directions/", //server endpoint address
"api-key"
