首先在geoserver上发布影像图的切片，并在tile layer上选择对应的坐标系及图片格式查看图层效果（多级图层）。
var viewer=new Cesium.Viewer("cesiumContainer",{
sceneMode : Cesium.SceneMode.SCENE2D,
timeline:false,
animation:false,//去除时间线条和Animation widget;
baseLayerPicker:false
});
var url='http://localhost:8080/geoserver/gwc/service/wmts/rest/nurc:shanxi04/{style}/{TileMatrixSet}/{TileMatrixSet}:{TileMatrix}/{TileRow}/{TileCol}?format=image/png'
var image = new Cesium.WebMapTileServiceImageryProvider({
url:url,
// layer:'nurc:shanxi04',
style : '',
// format : 'image/png',
tileMatrixSetID : 'EPSG:3857',
maximumLevel: 20
});
viewer.imageryLayers.addImageryProvider(image);
当版本过低时，TileMatrix无法直接获取
new Cesium.WebMapTileServiceImageryProvider({
url:'http://localhost:8080/geoserver/gwc/service/wmts/rest/nurc:shanxi04/{style}/{TileMatrixSet}/{TileMatrix}/{TileRow}/{TileCol}?format=image/png',
layer:'nurc:shanxi04',
style:'raster',
format:'image/png',
tileMatrixSetID:'EPSG:3857',
tileMatrixLabels:['EPSG:3857:0','EPSG:3857:1','EPSG:3857:2','EPSG:3857:3','EPSG:3857:4','EPSG:3857:5','EPSG:3857:6','EPSG:3857:7','EPSG:3857:8','EPSG:3857:9','EPSG:3857:10'],
maximumLevel: 20
})
(ps:当无法获取geoserver发布的影像图地址时，直接查看wmts服务，直接将请求地址放入浏览器查看，即可查看哪些属性有问题)
