概述：本节讲述Arcgis for Js加载ArcgisServer和GeoServer发布的wms服务。

1、定义resourceInfo

var resourceInfo = {
                        extent: new Extent(-126.40869140625,31.025390625,-109.66552734375,41.5283203125,{wkid: 4326}),
                        layerInfos: [],
                        version : '1.1.1'
                    };

2、加载ArcgisServer的wms

var agsWmsUrl = "http://localhost:6080/arcgis/services/road/MapServer/WMSServer";
                    var agsWmsLayer = new WMSLayer(agsWmsUrl,{resourceInfo: resourceInfo});
                    agsWmsLayer.setImageFormat("png");
                    agsWmsLayer.setVisibleLayers([0]);
                    map.addLayer(agsWmsLayer);

3、加载GeoServer的wms

var geoWmsUrl = "http://200.200.200.220:8080/geoserver/wms";
                    var geoWmsLayer = new WMSLayer(geoWmsUrl,{resourceInfo: resourceInfo});
                    geoWmsLayer.setImageFormat("png");
                    geoWmsLayer.setVisibleLayers(["capital","pro"]);
                    map.addLayer(geoWmsLayer);

完整代码如下：

    </style>
    <script src="http://localhost/arcgis_js_api/library/3.9/3.9/init.js"></script>
    <script type="text/javascript">
        var map;
        require([
            "esri/map",

            "esri/geometry/Extent",
            "dojo/domReady!"],
                function(Map,
                     WMSLayer,
                     Point,
                     Extent)
                {
                    map = new Map("map",{logo:false});

var resourceInfo = {
                        extent: new Extent(-126.40869140625,31.025390625,-109.66552734375,41.5283203125,{wkid: 4326}),
                        layerInfos: [],
                        version : '1.1.1'
                    };

var agsWmsUrl = "http://localhost:6080/arcgis/services/road/MapServer/WMSServer";
                    var agsWmsLayer = new WMSLayer(agsWmsUrl,{resourceInfo: resourceInfo});
                    agsWmsLayer.setImageFormat("png");
                    agsWmsLayer.setVisibleLayers([0]);
                    map.addLayer(agsWmsLayer);

var geoWmsUrl = "http://200.200.200.220:8080/geoserver/wms";
                    var geoWmsLayer = new WMSLayer(geoWmsUrl,{resourceInfo: resourceInfo});
                    geoWmsLayer.setImageFormat("png");
                    geoWmsLayer.setVisibleLayers(["capital","pro"]);
                    map.addLayer(geoWmsLayer);

                    var mapCenter = new Point(103.847, 36.0473, map.spatialReference);
                    map.centerAndZoom(mapCenter,4);
                });
    </script>
</head>
<body>
<div id="map">
