在Geoserver中做好發佈後，多個圖層顯示，通過在Layers中增加參數，加逗號，如下面紅色部分：
http://localhost:8080/geoserver/china/wms?service=WMS&version=1.1.0&request=GetMap[color=red]&layers=china:mysqlprovince_region[/color]&styles=&bbox=72.0,16.0,144.0,56.0&width=594
&height=330&srs=EPSG:4326&format=application/openlayers
http://localhost:8080/geoserver/china/wms?service=WMS&version=1.1.0&request=GetMap[color=red]&layers=china:mysqlprovince_region,china:mysqlprovince_point[/color]&styles=&bbox=72.0,16.0,144.0,56.0&width=594
&height=330&srs=EPSG:4326&format=application/openlayers
可以新建圖層組，然後用下面信息
http://localhost:8080/geoserver/china/wms?service=WMS&version=1.1.0&request=GetMap[color=red]&layers=mysqlchina[/color]&styles=&bbox=72.0,16.0,144.0,56.0&width=594&height=330&srs=EPSG:4326&format=application/openlayers
