首先是下载flex3，然后安装。
安装完成后，新建Flex Project,命名为Flex Demo，然后在项目中添加Library Path，添加agslib-1.3-2009-10-31.swc和FlexViewerLib.swc，如下图。
然后在FlexDemo.mxml中添加代码：
View Code 1 <? xml version = " 1.0 " encoding = " utf-8 " ?> 2 < mx:Application xmlns:mx = " http://www.adobe.com/2006/mxml " layout = " absolute " xmlns:esri = " http://www.esri.com/2008/ags " > 3 < esri:Map x = " 24 " y = " 0 " logoVisible = " false " panArrowsVisible = " true " > 4 < esri:ArcGISDynamicMapServiceLayer url = " http://www-e3017dbaae7/ArcGIS/rest/services/xinzheng/MapServer " > // 这个是发布好的服务 5 6 </ esri:ArcGISDynamicMapServiceLayer > 7 </ esri:Map > 8 9 </ mx:Application >这样即完成一个简单的地图服务发布，可以实现放大、缩小等gis功能。
