geoserver自带rest服务，可以发布shp，postgis等数据源。本文目前只说明怎么通过geoserver的rest发布postgis表数据。

1、maven添加geoserver-manager的依赖。

org.slf4j

jcl-over-slf4j

1.7.5

org.slf4j

slf4j-api

1.7.5

org.slf4j

slf4j-log4j12

1.7.5

nl.pdok

geoserver-manager

1.7.0-pdok2

2、java代码

import it.geosolutions.geoserver.rest.GeoServerRESTManager;

import it.geosolutions.geoserver.rest.GeoServerRESTPublisher;

import it.geosolutions.geoserver.rest.decoder.RESTDataStore;

import it.geosolutions.geoserver.rest.decoder.RESTLayer;

import it.geosolutions.geoserver.rest.encoder.GSLayerEncoder;

import it.geosolutions.geoserver.rest.encoder.datastore.GSPostGISDatastoreEncoder;

import it.geosolutions.geoserver.rest.encoder.feature.GSFeatureTypeEncoder;

import java.net.MalformedURLException;

import java.net.URL;

import java.util.List;

public class Temp {

public static void main(String[] args) throws MalformedURLException {

//GeoServer的连接配置

String url = "http://localhost:8080/geoserver" ;

String username = "admin" ;

String passwd = "geoserver" ;

//postgis连接配置

String postgisHost = "localhost" ;

int postgisPort = 5432 ;

String postgisUser = "postgres" ;

String postgisPassword = "19920318" ;

String postgisDatabase = "postgis_24_sample" ;

String ws = "wzf" ; //待创建和发布图层的工作区名称workspace

String store_name = "wafangdianshi" ; //待创建和发布图层的数据存储名称store

String table_name = "wafangdianshi" ; // 数据库要发布的表名称,后面图层名称和表名保持一致

//判断工作区(workspace)是否存在，不存在则创建

URL u = new URL(url);

GeoServerRESTManager manager = new GeoServerRESTManager(u, username, passwd);

GeoServerRESTPublisher publisher = manager.getPublisher() ;

List workspaces = manager.getReader().getWorkspaceNames();

if(!workspaces.contains(ws)){

boolean createws = publisher.createWorkspace(ws);

System.out.println("create ws : " + createws);

}else {

System.out.println("workspace已经存在了,ws :" + ws);

}

//判断数据存储(datastore)是否已经存在，不存在则创建

RESTDataStore restStore = manager.getReader().getDatastore(ws, store_name);

if(restStore == null){

GSPostGISDatastoreEncoder store = new GSPostGISDatastoreEncoder(store_name);

store.setHost(postgisHost);//设置url

store.setPort(postgisPort);//设置端口

store.setUser(postgisUser);// 数据库的用户名

store.setPassword(postgisPassword);// 数据库的密码

store.setDatabase(postgisDatabase);// 那个数据库;

store.setSchema("public"); //当前先默认使用public这个schema

store.setConnectionTimeout(20);// 超时设置

//store.setName(schema);

store.setMaxConnections(20); // 最大连接数

store.setMinConnections(1); // 最小连接数

store.setExposePrimaryKeys(true);

boolean createStore = manager.getStoreManager().create(ws, store);

System.out.println("create store : " + createStore);

} else {

System.out.println("数据存储已经存在了,store:" + store_name);

}

//判断图层是否已经存在，不存在则创建并发布

RESTLayer layer = manager.getReader().getLayer(ws, table_name);

if(layer == null){

GSFeatureTypeEncoder pds = new GSFeatureTypeEncoder();

pds.setTitle(table_name);

pds.setName(table_name);

pds.setSRS("EPSG:4326");

GSLayerEncoder layerEncoder = new GSLayerEncoder();

boolean publish = manager.getPublisher().publishDBLayer(ws, store_name, pds, layerEncoder);

System.out.println("publish : " + publish);

}else {

System.out.println("表已经发布过了,table:" + table_name);

}

}
