背景
GeoServer是一款很好用的开源GIS服务软件，而ArcGIS JS API是一款不错的webgis框架，通常ArcGIS JS API要搭配ArcGIS Server来使用，而ArcGIS Server售价往往过高。
通过加入GSR扩展，基本正常使用的FeatureServer和MapServer功能。就API而言，每个GeoServer工作区都被视为ArcGIS®服务。ArcGIS®URL在GeoServer中如下所示：
http://localhost:8080/geoserver/gsr/services/topp/MapServer/
http://localhost:8080/geoserver/gsr/services/topp/FeatureServer/
安装方法
下载GSR Jar包，放到目录里。设置Tomcat跨域。
