【Java+GS】快速上手GeoServer,并发布 Shapefile /PostGis / PostgreSQL
在Java环境下,要发布Shapefile、PostGIS或PostgreSQL数据到GeoServer,你需要使用GeoServer的API。以下是一个简化的代码示例,展示了如何使用GeoServer的REST API来发布一个Shapefile。
import org.apache.commons.fileupload.disk.DiskFileItem;
import org.geoserver.catalog.Catalog;
import org.geoserver.catalog.DataStoreInfo;
import org.geoserver.catalog.FeatureInfo;
import org.geoserver.catalog.impl.CatalogImpl;
import org.geoserver.rest.RestletData;
import org.geoserver.rest.RestletDataStore;
import org.restlet.data.MediaType;
import org.restlet.data.Reference;
import org.restlet.data.Request;
import org.restlet.data.Response;
import org.restlet.resource.ClientResource;
import java.io.File;
import java.net.URI;
public class GeoServerPublisher {
private final String geoServerUrl;
private final String user;
private final String password;
public GeoServerPublisher(String geoServerUrl, String user, String password) {
this.geoServerUrl = geoServerUrl;
this.user = user;
this.password = password;
}
public void publishShapefile(String workspace, String storeName, String filePath) throws Exception {
// 1. 创建DataStore
createPostGISDataStore(workspace, storeName, "your_db_host", "your_db_name", "your_db_user", "your_db_password");
// 2. 上传Shapefile
uploadShapefile(workspace, storeName, filePath);
// 3. 发布Feature
publishFeature(workspace, storeName, new File(filePath));
}
private void createPostGISDataStore(String workspace, String storeName, String host, String dbName, String user, String password) {
// 实现创建PostGIS数据源的逻辑
}
private void uploadShapefile(String workspace, String storeName, String filePath) {
// 实现上传Shapefile的逻辑
}
private void publishFeature(String workspace, String storeName, File shapefile) throws Exception {
// 准备Restlet请求
Request request = new Request();
Response response = new Response(request);
Catalog catalog = new CatalogImpl(request, response);
// 获取数据存储
DataStoreInfo dataStore = catalog.getDataStoreByName(workspace, storeName);
RestletDataStore dataStoreResource = new RestletDataStore(dataStore, request, response);
// 设置请求参数
request.setResourceRef(new Reference(geoServerUrl + "/rest/workspaces/" + workspace
