1、将GeowebCache的war包解压到tomcat的webapp下，打开war包中的WEB-INF中的web.xml文件，同时创建一个你想保存geowencache的切片的空文件夹，例如我命名叫arcgis

                  

web.xml文件中 添加<context-param>节点，param-value是你所建的文件夹

<context-param>
<param-name>GEOWEBCACHE_CACHE_DIR</param-name>
<param-value>D:\Program Files\Apache Tomcat\webapps\geowebcache\WEB-INF\arcgis</param-value>
</context-param>

2、在重启动tomcat 之后我们在arcgis文件夹中可以看到

3、打开webwebcache.xml文件，在<layer>…</layer>节点中添加如下节点：

<arcgisLayer>
<name>arcgis_cache</name>
<tilingScheme>E:\\tile\\arcgis\\Layers\\conf.xml</tilingScheme>
<tileCachePath>E:\\tile\\arcgis\Layers\\_alllayers</tileCachePath>
<hexZoom>false</hexZoom>
</arcgisLayer>

4、配置完以后我发现我无法启动geowebcache，日志报错

10 四月 18:12:15 (main) WARN [support.XmlWebApplicationContext] - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gwcXmlConfig' defined in ServletContext resource [/WEB-INF/geowebcache-core-context.xml]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: No ArcGISCacheGridsetConfiguration could be found

网上找到了解决方法

找到geowebcache-core-context文件，往里面添加

<bean id="gwcArcGIGridsetConfigutation" class="org.geowebcache.arcgis.layer.ArcGISCacheGridsetConfiguration"/>

5、加完之后可以在geowebcache的list中查看到自己添加的瓦片，但是却不能预览，比例尺也是1：NAN

网上解释说高版本geowebcache可能无法预览，查看他的预览页面发现是OL3的库，因为我用的是OL4的库，不影响OL或者leaflet加载

6、重启一下服务，刷新一下

var format = 'image/png';
var tiled = new ol.layer.Tile({
//visible: false,
source: new ol.source.TileWMS({
url: 'http://localhost:8888/geowebcache/service/wms',
params: {
'FORMAT': format,
'VERSION': '1.0.0',
tiled: true,
"LAYERS": 'arcgis_cache',
"exceptions": 'application/vnd.ogc.se_inimage', }
})
});
var view = new ol.View({
projection:"EPSG:4326",
zoom: 13,
center: [113.33, 34.01]
});
var map = new ol.Map({
target: 'map',
layers: [tiled],
view:view
});
