服务提供者层的扩展

ProviderContextAware 用于获取服务提供者上下文，通过服务提供者上下文，可以获取该服务提供者对应的配置信息。

服务提供者接口

SuperMap iServer 已有的服务提供者类型有地图服务提供者、数据服务提供者、三维服务提供者、空间分析服务提供者、交通网络分析服务提供者。针对这些服务提供者，SuperMap iServer 已经进行了实现，从而提供了 GIS 功能的来源，支撑 SuperMap iServer 提供各种 GIS 功能（参见：服务提供者介绍）。

扩展服务提供者，对已有的服务提供者类型重新实现，可以扩宽 SuperMap iServer 提供 GIS 功能的来源。

在定义新的服务提供者类型，实现特定行业领域的功能时，不受以上接口限制。

服务提供者上下文

在服务提供者实现类中，可以通过 ProviderContextAware 接口获取服务提供者上下文，通过服务提供者上下文，可以获取获取服务提供者配置信息。

用户自定义服务服务配置信息在 iserver-services.xml 中（详见iServer 配置文件说明），配置服务提供者时定制，结构由服务提供者配置类确定。服务提供者配置如下：

其中，SampleProviderSetting 是 SampleProvider 对应的配置类，param1对应 SampleProviderSetting 类的属性，通过使用服务提供者配置类，可以在 SuperMap iServer 中构建同种类型、不同来源的服务提供者。

在服务提供者实现类中，可以通过 ProviderContextAware 接口获取服务提供者上下文，并通过服务提供者上下文获取服务提供者配置信息，具体方式如下：

SampleProviderSetting sampleProviderSetting = context.getConfig(SampleProviderSetting.class);

sampleProviderSetting 对象即对应配置文件中<provider/>下的<config/>配置项。

RemoteTiledMapProviderBase 扩展

扩展介绍

RemoteTileProviderBase 是用于聚合第三方地图服务的抽象类，用于构建在线服务提供者，实现了 ProviderContextAware 服务提供者上下文依赖库接口和 MapProvider 地图服务提供者接口。

该类的主要出图方法是 getTileImageUrl(TileImageParameter tileImageParameter)。

用户可以继承 RemoteTileProviderBase 抽象类，来聚合第三方地图服务。

将编译好的扩展类的 class 文件放到%SuperMap iServer_HOME%\webap\iserver\WEB-INF\classes 目录下(默认情况下没有 classes 目录，需要新建)或是编译好的 jar 包放到%SuperMap iServer_HOME%\webapp\ iserver\WEB-INF\lib\目录下，iServer 就可以使用扩展的服务提供者类，关于如何配置服务提供者，详见通过 XML 文件配置服务提供者。

该类 cacheEnabled()，可以返回 true 或者 false 来设置是否使用缓存。

为 true 时，使用图片缓存，目前的图片缓存目录即地图服务提供者配置对象 MapProviderSetting.getOutputPath()目录，缓存路径为“\cache\地图名_图片宽度 x 图片高度\比例尺倒数\图片 x 索引\图片 y 索引.图片格式后缀”，同时，该类对访问的第三方地图服务也进行了缓存，缓存路径为“\cache\http\地图名_图片宽度 x 图片高度\比例尺倒数\图片 x 索引\图片 y 索引.图片格式后缀”。

这里扩展一个地图服务提供者。GoogleMapsMapProvider 继承 RemoteTileProviderBase 实现。你可以在%SuperMap iServer_HOME%/samples/code/DSSE/GoogleMapsProviderSample 位置找到该示例的源代码。

import com.supermap.services.components.commontypes.LayerType;
import com.supermap.services.components.commontypes.Rectangle2D;
public class GoogleMapLayer extends Layer {
    private static final long serialVersionUID = 1L;
    public GoogleMapLayer() {
        this.type = LayerType.CUSTOM;
    }
    @Override
    public Layer copy() {
        GoogleMapLayer googleLayer = new GoogleMapLayer();
        googleLayer.name = this.name;
        googleLayer.type = this.type;
        googleLayer.bounds = new Rectangle2D(this.bounds);
        googleLayer.caption = this.caption;
        googleLayer.visible = this.visible;
        return googleLayer;
    }
}

编译后的 Jar 放到 %SuperMap iServer_HOME%/webapps/iserver/WEB-INF/lib 目录。

新建一个使用 mapProvider-GoogleMaps 的“地图服务组件”map-google，发布为 rest、WMS 1.1.1 服务：

即可通过根 URI：http://<host>:<port>/iserver/services/map-google/rest 访问地图 REST 功能。通过 http://<host>:<port>/iserver/services/map-google/rest/maps/googlemaps.ijs 访问地图（googlemaps 为地图名，在 GoogleMapsMapProvider 实现类中声明），结果如下：

LocalTileProviderBase 扩展

扩展介绍

LocalTileProviderBase 是用于扩展本地地图瓦片服务的抽象类，实现了 ProviderContextAware 服务提供者上下文依赖库接口和 MapProvider 地图服务提供者接口。

该类的主要出图方法是 getTileImage(TiledMapProviderBase.TileImageParameterparamTileImageParameter）。

用户可以继承 LocalTileProviderBase 抽象类，来扩展本地地图服务。

该类 cacheEnabled()，可以返回 true 或者 false 来设置是否使用缓存。

扩展示例

本示例介绍通过继承自 LocalTileProviderBase 的 ArcGISExplodedCacheMapProvider 类来实现将本地的 ArcGIS Server 地图切片发布为 Supermap 地图服务的流程，你可以在%SuperMap iServer_HOME%/samples/code/DSSE/ArcGISExplodedCacheMapProviderSample 位置找到该示例的源代码。

注意：在通过 ArcGIS Server 进行切图的时候，选择的存储格式为”松散”的格式，分块格式选择 PNG8、PNG24、PNG32。

ArcGISExplodedCacheMapProviderSetting 类，继承自 MapProviderSetting 类，用于扩展地图服务提供者配置，完成一些特定地图参数的设置。其中的 cachePath 表示地图切片路径、mapName 表示地图名。

package com.supermap.sample.serviceprovider;
import com.supermap.services.components.spi.MapProviderSetting;
public class ArcGISExplodedCacheMapProviderSetting extends MapProviderSetting {
    private static final long serialVersionUID = 1L;
    private String cachePath;
    private String mapName;
    public String getMapName() {
        return mapName;
    }
    public void setMapName(String mapName) {
        this.mapName = mapName;
    }
    public String getCachePath() {
        return cachePath;
    }
    public void setCachePath(String cachePath) {
        this.cachePath = cachePath;
    }
}

配置类使用扩展自 MapProviderSetting 的 ArcGISExplodedCacheMapProviderSetting 类，其中必须要配置<cachePath>切片路径、并且用户可以选择性配置<mapName>地图名，当用户未配置或配置的地图名为空时，地图名将采用默认值，配置如下：

编译后的 Jar 放到 %SuperMap iServer_HOME%/webapps/iserver/WEB-INF/lib 目录。

新建一个使用 mapProvider-ArcGISMaps 的“地图服务组件”map-arcgis，发布为 rest、WMS 1.1.1 服务：

即可通过根 URI：http://<host>:<port>/iserver/services/map-arcgis/rest 访问地图 REST 功能。通过 http://<host>:<port>/iserver/services/map-arcgis/rest/maps/arcgismaps.ijs 访问地图（arcgismaps 为地图名，在 ArcGISExplodedCacheMapProvider 实现类中声明），结果如下：

扩展一个 TMSTilesMapProvider

本示例介绍通过继承自 ZXYTilesMapProvider 的 TMSTilesMapProvider 类来实现将本地的 TMS 地图切片发布为 Supermap 地图服务的流程，你可以在%SuperMap iServer_HOME%/samples/code/DSSE/TMSTilesMapProviderSample 位置找到该示例的源代码。

TMSTilesMapProviderSetting 类，继承自 ZXYTilesMapProviderSetting 类，用于扩展地图服务提供者配置，完成一些特定地图参数的设置。TMSTilesMapProviderSetting 实现类代码如下：

	
package com.supermap.sample.serviceprovider;
import com.supermap.services.components.spi.MapProviderSetting;
public class ArcGISExplodedCacheMapProviderSetting extends MapProviderSetting {
    private static final long serialVersionUID = 1L;
    private String cachePath;
    private String mapName;
    public String getMapName() {
        return mapName;
    }
    public void setMapName(String mapName) {
        this.mapName = mapName;
    }
    public String getCachePath() {
        return cachePath;
    }
    public void setCachePath(String cachePath) {
        this.cachePath = cachePath;
    }
}

将编译好的扩展类的 class 文件放到 %SuperMap iServer_Home%\webap\iserver\WEB-INF\classes 目录下（默认情况下没有classes目录，需要新建），或将编译后的 Jar 放到 %SuperMap iServer_HOME%/webapps/iserver/WEB-INF/lib 目录下。

在 iserver-services.xml（位于%SuperMap iServer Java_HOME%/webapps/iserver/WEB-INF）配置服务提供者，配置如下：

其中<filePath>为必须参数，表示 TMS 瓦片路径，路径需要写到 TMS 瓦片地图名的上一级。如，示例中TMS 瓦片存储路径为 D:/sample/TMSTile_file/<MapName>/<Z>/<X>/<Y> ，则 filePath 应为 D:/sample/TMSTile_file。

在 iserver-services.xml 中配置地图服务组件 TMSTiles-test，发布为rest服务：

即可通过根 URI：http://<host>:<port>/iserver/services/map-TMSTiles-test/rest 访问地图 REST 功能。通过 http://<host>:<port>/iserver/services/map-TMSTiles-test/rest/maps/test.leaflet 访问地图。

扩展类型	继承的类/实现的接口	备注
地图服务提供者	com.supermap.services.components.spi.MapProvider	所有的地图服务提供者都实现该接口。实现该接口的服务提供者可以被地图服务组件使用。
	com.supermap.services.components.spi.AbstractRestMapProvider	封装了访问 REST 地图服务所需的基本功能，所有使用 REST 地图服务的服务提供者都可使用此类扩展。
	com.supermap.services.components.spi.RemoteTiledMapProviderBase	RemoteTileProviderBase 是用于聚合第三方地图服务的抽象类，用于构建在线服务提供者，实现了 ProviderContextAware 服务提供者上下文依赖库接口和 MapProvider 地图服务提供者接口。 (参见：RemoteTiledMapProviderBase_扩展）
	com.supermap.services.components.spi.LocalTiledMapProviderBase	LocalTileProviderBase 是用于扩展本地地图瓦片服务的抽象类，本地的地图瓦片来源于 ArcGIS 切图所得。 (参见：LocalTiledMapProviderBase_扩展）
