1. 点击Logo -》版本号 -》查看自己的wms地址


2. 设置范围


将图中的范围以此填写到

1
var extent = [924029.4389153644, 3148870.100464709, 975418.6183263285, 3193088.3305712156];

source: new ol.source.TileWMS({
                   url: 'http://localhost:8089/geoserver/webgis_test/wms',
                   params: {
                       'LAYERS': 'webgis_test:beijing',
                       'TILED': false
                   },
                   serverType: 'geoserver'
               })
  • url为刚才找到的wms地址
  • ‘LAYERS’的值为图层名称

4. 定义地图对象

var map = new ol.Map({
             layers: tiled,
             target: 'map',
             view: new ol.View({
                 projection: 'EPSG:3857',
                 zoom: 4
             }),
             controls: ol.control.defaults({
                 attributionOptions: {
                     collapsible: false
                 }
             })

修改projection: 'EPSG:3857',中的3857为图层的坐标代码
