这里说的tomcat切片，是指arcgis server切片后，把切片图片文件用tomcat发布（其他任意web服务器发布都行）

        //添加tomcat切片图层addTomcatTileLayer: function () {//图层配置let layerConfig = {//切片所在的url，url结尾应该是 _alllayers/url: "http://xxx/Layers/_alllayers/",//图层范围tileExtent: "-0.5,-973.5,1919.5,0.5",//切片文件格式tileFormat: "png",//切片级别tileLevel: "0,1,2,3,4,5,6,7",//切片分辨率tileResolution: "2.1166709000084669,1.8520870375074086,1.5875031750063502,1.3229193125052918,1.0583354500042335,0.79375158750317509,0.52916772500211673,0.26458386250105836",//切片比例尺tileScale: "8000,7000,6000,5000,4000,3000,2000,1000",//切片大小colstileSizeCols: 512,//切片大小rowstileSizeRows: 512,//地图原点xtileZeroX: -5123200,//地图原点ytileZeroY: 10002100,//压缩质量compressionQuality: "0",//图层的坐标系wkidwkid: "4547",transparency: null,};//添加图层到地图//参数3：图层id，可以为空，空则自动分配this.map.add(this.apiInstance.createWebTileLayer(null, layerConfig)[0]);},

上述封装的部分函数

createWebTileLayer : function (map, layer, id, click) {var titleExtent = [];if (!!layer.tileExtent) {layer.tileExtent.split(',').forEach(function (extent) {titleExtent.push(parseFloat(extent))})}var tileInfoConfig = {url: layer.url,  //瓦片大小"size": parseFloat(layer.tileSizeRows),  //瓦片大小"compressionQuality": 0,"origin": {"x": parseFloat(layer.tileZeroX), "y": parseFloat(layer.tileZeroY)},  //切图原点"spatialReference": {"wkid": parseInt(layer.wkid)},  //瓦片比例尺"format": layer.tileFormat};var tileResolutions = layer.tileResolution.split(',');var tileLevels = layer.tileLevel.split(',');var tileScales = layer.tileScale.split(',');var lods = [];if (tileResolutions.length !== tileLevels.length || tileScales.length !== tileResolutions.length) {console.error('地图配置有误', layer);}else {//lods：等级、比例尺、分辨率。从ArcGIS切图配置文件conf.xml中获取。设置lods会影响地图比例尺控件的范围。for (var i = 0; i < tileScales.length; i++) {lods.push({"level": parseInt(tileLevels[i]),"resolution": parseFloat(tileResolutions[i]),"scale": parseFloat(tileScales[i])});}tileInfoConfig.lods = lods;var tileInfo = new instance.TileInfo(tileInfoConfig);var spatialReference = new instance.SpatialReference({wkid: parseInt(layer.wkid)});var fullExtent = new instance.Extent(titleExtent[0], titleExtent[1], titleExtent[2], titleExtent[3], spatialReference);if (layer.type == 'ArcgisTile') {var tiledLayer = new instance.WebTileLayer({id: id,urlTemplate: layer.url + '/tile/{level}/{row}/{col}',copyright: "",spatialReference: spatialReference,fullExtent: fullExtent,tileInfo: tileInfo});} else {var tiledLayer = new instance.WebTileLayer({id: id,urlTemplate: layer.url,copyright: "",spatialReference: spatialReference,fullExtent: fullExtent,tileInfo: tileInfo,getTileUrl: function (level, row, col) {if (layer.ext1 == 'superMap') {return this.urlTemplate + level + "/" + row + "/" + col + "." + this.tileInfo.format;}return this.urlTemplate + "L" + dojo.string.pad(level, 2, '0') + "/" + "R" + (dojo.string.pad(row.toString(16), 8, '0')).toUpperCase() + "/" + "C" + (dojo.string.pad(col.toString(16), 8, '0')).toUpperCase() + "." + this.tileInfo.format;}});}if (!!click) {tiledLayer.on('layerview-create', function (evt) {var graView = evt.view;var graLayerView = evt.layerView;var layerId = evt.layerView.layer.id;graView.on('click', function (event) {graView.hitTest(event).then(click);});});}if (!!map) {map.add(tiledLayer);}return [tiledLayer];}
};

arcgis rest图层指用arcgis server发布的地图服务，用rest方式加载

        //添加arcgis rest图层addArcgisRestLayer: function () {//图层配置//PS：arcgis rest图层传入最小配置只要url就行，因为url有服务的详细配置（浏览器访问url可看详细配置信息），jsapi会自己去读let layerConfig = {//地图服务url，url结尾应该是 /MapServerurl: "http://xxx/arcgis/rest/services/yyy/MapServer",//图层id，可以为空，空则自动分配// id: "eeee"
            };//根据图层配置新建图层let layer = new this.apiInstance.MapImageLayer(layerConfig);//图层添加到mapthis.map.add(layer);},

天地图互联网版，注意这里固定是加载wgs84坐标系的（另一种是web买卡托坐标，不支持）

        //添加天地图（互联网版）图层addTdtLayer: function () {//创建天地图图层//图层配置//PS：arcgis rest图层传入最小配置只要url就行，因为url有服务的详细配置（浏览器访问url可看详细配置信息），jsapi会自己去读let layerConfig = {//图层id，可以为空，空则自动分配// id: "eeee"
            };//参数2：天地图图层类型，支持以下值：img=影像——经纬度，cia=影像注记——经纬度，vec=矢量——经纬度，cva=矢量注记——经纬度，ter=地形图——经纬度，cta=地形图注记——经纬度//参数3：图层配置，值同官方创建图层的配置，也可空let layer = mapUtil.layer.createTdtLayer(this.apiInstance, "vec", layerConfig);//图层添加到mapthis.map.add(layer);},
