                              }));
               });
          })

关于查询的方式:

点查询Filter

<Filter xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">
<Intersects>
<PropertyName>the_geom</PropertyName>
<gml:Envelope srsName="EPSG:4326">
<gml:lowerCorner>xxx yyy</gml:lowerCorner>
<gml:upperCorner>xxx yyy</gml:upperCorner>
</gml:Envelope>
</Intersects>
</Filter>

还有自定义多边形查询，

还有就是多多学习自己写Filter，需要的参数学习可以看下http://www.gisvip.com/bbs/forum.php?mod=viewthread&tid=2723
