Openlayers之加载ArcgisServer的切片（TileArcGISRest加载方式）
1、先使用ArcGIS Server切好瓦片地图，切完以后在ArcGIS Server Manager中找到该瓦片的访问地址，如图所示：
2、ol.source.TileArcGISRest类
Openlayers的API中提供了一个专门用来加载ArcGIS Server切片服务的类ol.source.TileArcGISRest，其具体描述如下：
Layer source for tile data from ArcGIS Rest services. Map and ImageServices are supported.
For cached ArcGIS services, better performance is available using the
ol.source.XYZ data source.
而且官方也给了说明，对于具有瓦片缓存的服务，使用ol.source.XYZ 来加载性能更好，所以使用这种方式加载瓦片不是最好的选择。ol.source.TileArcGISRest
类的具体构造参数我就不再说明，自己去看官方API，下面开始加载ArcGIS Server带有缓存的瓦片服务（没有缓存的加载方式也一样）。
3、代码
