如何更改图标 Marker Gmap Primefaces？

Question

大家好，我从 Gmap Primefaces 组件开始，想知道如何更改图标。 我依赖于 Primefaces 的展示：

this.advancedModel.addOverlay(new Marker(coord1, "Konyaalti", "konyaalti.png", "http://maps.google.com/mapfiles/ms/micons/blue-dot.png"));
this.advancedModel.addOverlay(new Marker(coord2, "Ataturk Parki", "ataturkparki.png"));
this.advancedModel.addOverlay(new Marker(coord4, "Kaleici", "kaleici.png", "http://maps.google.com/mapfiles/ms/micons/pink-dot.png"));
this.advancedModel.addOverlay(new Marker(coord3, "Karaalioglu Parki", "karaalioglu.png", "http://maps.google.com/mapfiles/ms/micons/yellow-dot.png"));  

我已将图标下载到我的项目中，并已路由，但无法正常工作，标记图标是示例。

StringBuilder ruta = new StringBuilder();
ruta.append(getContext().getRealPath(Constantes.DIVISOR));
ruta.append("resources/maps/images/");

StringBuilder bluedot = new StringBuilder(); 
bluedot.append(ruta);
bluedot.append("blue-dot");
bluedot.append(Constantes.EXTENSION_FORMATO_PNG);

StringBuilder pinkdot = new StringBuilder(); 
pinkdot.append(ruta);
pinkdot.append("pink-dot");
pinkdot.append(Constantes.EXTENSION_FORMATO_PNG);

StringBuilder yellowdot = new StringBuilder(); 
yellowdot.append(ruta);
yellowdot.append("yellow-dot");
yellowdot.append(Constantes.EXTENSION_FORMATO_PNG);

System.out.println("---> "+bluedot.toString());

//Icons and Data
this.advancedModel.addOverlay(new Marker(coord1, "Konyaalti", "konyaalti.png", bluedot.toString()));
this.advancedModel.addOverlay(new Marker(coord2, "Ataturk Parki", "ataturkparki.png"));
this.advancedModel.addOverlay(new Marker(coord4, "Kaleici", "kaleici.png", pinkdot.toString()));
this.advancedModel.addOverlay(new Marker(coord3, "Karaalioglu Parki", "karaalioglu.png", yellowdot.toString()));

好了图片文件路径，但是还是不考虑Marker PrimeFaces，应该是哪个？？？

Console:

D:\springsource\apache tomcat 7.0.53\webapps\geotermica\resources\maps\images\blue-dot.png

如果要指向文件系统上的文件，应使用file:// 方案。见：How to specify a local file within html using the file: scheme?

如果您想创建一个相对 URL 来从您的网络服务器获取图像，您应该使用 context path 而不是真实路径：

StringBuilder ruta = new StringBuilder();
ruta.append(FacesContext.getCurrentInstance().getExternalContext().getRequestContextPath());
ruta.append("/resources/maps/images/");
