1、在arcmap中加载图层，并发布成arcser服务（服务名dizhi），记住勾选FeatureServer服务
2、在arcserver manger中查看刚才发布的服务
3、访问featureServer服务，点击你需要查询的图层，点击query
4、进行空间/属性查询
4.1 矩形查询，
1）不同geometry type对应的请求json体不同
2）注意wkid要与图层的实际坐标系一致
3）注意选对spatial relationShip
{ "xmin" : -39.72230000048876, "ymin" : 39.4294999986887, "xmax" : 117.51159999892116, "ymax" : 116.2474999986589, "spatialReference" : {"wkid" : 4326} }
4.2 多边形查询
