GeoWebCache配置.doc

搞定GeoWebCache配置 折腾了好久，终于搞定了开源WebGIS地图服务器geoserver的切片地图服务GeoWebCache配置。开源的东西有一个不好的地方就是没有很规整的官方文档，所以学习起来比较吃力。就如GeoWebcache，高版本和低版本的配置就是不一样的。geowebcache-0.8.3里面配置地图缓存地址的时候是：http:/localhost:8989/geowebcache/service/wms，而我用的是geowebcache-1.2.2，geoserver服务器的版本是geoserver2.0.1，配置地图缓存地址用上面那个就行不通了，经过多方测试，才试出来：http:/localhost:8080/geoserver/gwc/service/wms，话不多说，贴下代码和实验效果图： /* General settings */ body font-family: Verdana, Geneva, Arial, Helvetica, sans-serif; font-size: small; /* The map and the location bar */ #map clear: both; position: relative; width: 900px; height: 600px; border: 1px solid black; var map; function init() var mapOptions = resolutions: 0.703125, 0.3515625, 0.17578125, 0.087890625, 0.0439453125, 0.02197265625, 0.010986328125, 0.0054931640625, 0.00274658203125, 0.001373291015625, 6.866455078125E-4, 3.4332275390625E-4, 1.71661376953125E-4, 8.58306884765625E-5, 4.291534423828125E-5, 2.1457672119140625E-5, 1.0728836059570312E-5, 5.364418029785156E-6, 2.682209014892578E-6, 1.341104507446289E-6, 6.705522537231445E-7, 3.3527612686157227E-7, 1.6763806343078613E-7, 8.381903171539307E-8, 4.190951585769653E-8, 2.0954757928848267E-8, projection: new OpenLayers.Projection(EPSG:4326), maxExtent: new OpenLayers.Bounds(-180.0,-90.0,180.0,90.0), units: degrees, controls: ; map = new OpenLayers.Map(map, mapOptions ); map.addControl(new OpenLayers.Control.PanZoomBar( position: new OpenLayers.Pixel(2, 15); map.addControl(new OpenLayers.Control.Navigation(); map.addControl(new OpenLayers.Control.Scale($(scale); map.addControl(new OpenLayers.Control.MousePosition(element: $(location); var serURL = http:/localhost:8080/geoserver/gwc/service/wms; var bounds = new OpenLayers.Bounds(73.447,6.319,135.086,53.558); /定义基础图层 var layerblock = new OpenLayers.Layer.WMS( china:GuojieYSJ, serURL , layers: china:GuojieYSJ, srs: , style: , format: image/jpeg, transparent: false , tileSize: new OpenLayers.Size(256,256) , isBaseLayer:true ); var ShouduHSJXZZX = new OpenLayers.Layer.WMS( china:ShouduHSJXZZX, serURL , layers: china:ShouduHSJXZZX, srs: , style: , format: image/png, transparent: true , tileSize: new OpenLayers.Size(256,256) , isBaseLayer:false ); map.addLayers(layerblock,ShouduHSJXZZX); map.addControl( new OpenLayers.Control.LayerSwitcher() ); map.addControl(new OpenLayers.Control.OverviewMap(); map.addControl(ne
