Interface MapServerPort常用的方法：
mapServer.getDefaultMapName() 獲得默認地圖名
mapServer.queryFeatureCount(String mapName , int layerId ,SpatialFilter sf) return int 獲得指定圖層查詢到的要素總數
mapServer.queryFeatureData(String mapName , int layerId ,SpatialFilter sf) return RecordSet 獲得指定圖層查詢到的要素集(包含所有屬性字段)
mapServer.getDefaultMapName() return String 返回默認地圖名稱
mapServer.hasLayerCache(String mapName, int layerID) return bool 返回指定圖層是否是緩存圖層
