1、访问WMS服务

首先需要发布WMS服务，才能进行地图WMS服务访问。这里不说怎么发布WMS服务，直接看怎么调用，代码如下：

2、添加Googlemap图层

1）、申请Google 地图key：

申请Google 地图 API 的keyhttp://www.google.com/intl/zh-CN/apis/maps/signup.html
　　申请的url填写为： http://yourhost/:8080/

2）、在HTml中添加地图引用：

<script charset="utf-8" src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIAAAAB6A1_oyBce6PP1YjsfO0_hQNFBmrp5F93wWCsYm0Hw_cwNHkjhT-j-A3DS2sOTKDXHL3iAgKKdglFQ" type="text/javascript">
</script>

3）、在init方法中加入如下代码：

//Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->//加载google地图
var googlesatellite = new OpenLayers.Layer.Google("Google Satellite", {type:G_SATELLITE_MAP, 'maxZoomLevel':18} );
map.addLayers([googlesatellite]);
var googlebybrid = new OpenLayers.Layer.Google("Google Hybrid", {type:G_HYBRID_MAP});
map.addLayers([googlebybrid]);
var GMapsStreets = new OpenLayers.Layer.Google("Google Streets", {type:G_NORMAL_MAP, 'maxZoomLevel':18} );
map.addLayers([GMapsStreets]);
