数据在GeoServer中配置好之后，可以HTML代码编写OpenLayers的WMS的请求服务。编写好之后，可以在浏览器上查看地图。

地理数据在OpenLayers上显示

用到的HTML代码：

 

   

        #map {

            width: 800px;

            height: 434px;

            border: 1px solid black;

        }

   

 type="text/javascript">                                                                                                                                    

   

        function init(){

          var map = new OpenLayers.Map('map', {controls:[], 'projection':

              'EPSG:4326', 'units':'degrees'});          

          OpenLayers.IMAGE_RELOAD_ATTEMPTS = 5;

        

          // setup tiled layer

          var bounds = new OpenLayers.Bounds(70.56262702941892,

              16.39964122772222,137.82589988708528,55.32298831939698)

          var tiled = new OpenLayers.Layer.WMS(

            "topp:china", "http://localhost:8080/geoserver/wms",

            {

              srs: 'EPSG:4326',

              width: '800',

              styles: '',

              height: '434',

              layers: 'topp:china',

              format: 'image/png', tiled: 'true', tilesOrigin :

              "70.56262702941892,16.39964122772222"

            },

            {maxExtent: bounds, maxResolution: 0.26274715960025924, projection:

             "EPSG:4326", buffer: 0}

          );

          map.addLayer(tiled);

 

            map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);

            map.addControl( new OpenLayers.Control.PanZoomBar() );

            map.addControl( new OpenLayers.Control.LayerSwitcher() );           

        }
