使用java进行路由跟踪
我想追踪不同点之间的轨迹 对于测试，我创建点并尝试在这些点之间建立链接 这是我的密码使用java进行路由跟踪,java,vaadin,openstreetmap,Java,Vaadin,Openstreetmap,我想追踪不同点之间的轨迹 对于测试，我创建点并尝试在这些点之间建立链接 这是我的密码 OpenStreetMapLayer osm = new OpenStreetMapLayer(); map.addLayer(vectorLayer); List<Point>points= new ArrayList<Point>(); Point point = new Point(44.272872,4.27826); Point point2 = new Po
