Geoserver项目开发(三) -图层加载限制(二)

图层加载限制通过geoserver提供的图层组可以解决。

首先将图层分类。

我的图层分了4组图层组。

 

region组：

topp:bou2_4p,topp:shijie_region,topp:huposhuiku_region,topp:shuangxianhe_region,topp:lvdi_region,

topp:jumindi_region,topp:chengshijiequ_region,topp:jiaoqudiwu_region,topp:shiqudaolu_region,

topp:qitadaolu_region,topp:xianjie_region

 

polyline组：

topp:guihuadaolu_polyline,topp:gongyuanlu_polyline,topp:qitadaolu_polyline,topp:xiaolu_polyline,

topp:chengshijiequ_polyline,topp:shiqudaolu_polyline,topp:sijidaolu_polyline,topp:ccsanjidaolu_polyline,

topp:sanjidaolu_polyline,topp:erjidaolu_polyline,topp:yijidaolu_polyline,topp:huanchenglu_polyline,

topp:ccxianxiangdao_polyline,topp:xianxiangdao_polyline,topp:tielu_polyline,topp:guodao_polyline,

topp:shengdao_polyline,topp:zaijiangaosu_polyline,topp:gaosugonglu_polyline

 

point组：

topp:daolumingcheng_point,topp:xingzhengbiaoji_point,topp:jiaoqudiwu_font_point,

topp:jiaoqudiwu_point,topp:shiqudiwu_point,topp:qiao_point,topp:shanming_point

 

polyline组：(按功能把 水域 的图层分开了)

topp:suidao_polyline,topp:shuangxianhe_polyline,topp:huposhuiku_polyline,topp:danxianhe_polyline,

topp:chedu_polyline,topp:shuizhashuiba_polyline,topp:qiao_polyline,topp:ti_polyline

 

 

分完组后通过如下步骤增加图层组。

配置-->WMS-->内容

 

创建图层组名称：jilin
基础地理图层：topp:bou2_4p,topp:shijie_region,topp:huposhuiku_region,topp:shuangxianhe_region,topp:lvdi_region,

topp:jumindi_region,topp:chengshijiequ_region,topp:jiaoqudiwu_region,topp:shiqudaolu_region,

topp:qitadaolu_region,topp:xianjie_region

点击生成按钮。

 

依次添加图层组。

 

 

 

配置完毕后，页面访问可以通过如下访问了。
layer = new OpenLayers.Layer.WMS( "topp:shijie_region - Untiled", "http://localhost:8080/geoserver/wms", { width: '800', srs: 'EPSG:4326', layers:'jilin,shui,daolu,point', height: '560', styles: '', format: 'image/png' }, {singleTile: true, ratio: 1} );
