                                data.put("geom",geometry);

                            } else {

                        //新增数据到图层数据表
                        geoserverDao.addTableDateList(tableName,heads,data);
                        
                        //发布该图层
                        Boolean addLayer = geoServer.addLayer(null,null,tableName,null);
                        if(!addLayer){
                            throw new KspException(WebErrorCode.INTERNAL_PROCESS_ERROR, "发布数据图层失败", null, null);
                        }
                    }

                }
            }
        }
    }
   
}

上面所调用的dao方法：

public interface GeoserverDao {

	@Update("CREATE SEQUENCE \"public\".\"${tableName}_seq\" ")
	public void createSequence(@Param("tableName")String tableName);

	@Update("")
	public void createTable(@Param("tableName")String tableName,@Param("heads")List<Map<String, Object>> heads);


	@Insert("")
	public void addTableDateList(@Param("tableName")String tableName,@Param("heads")List<Map<String, Object>> heads,@Param("data")LinkedHashMap<String, Object> data);

}

2.通过rest发布geoserver图层

创建要用的工作区和数据储存：



引入geoserver依赖：

		<dependency>
            <groupId>nl.pdokgroupId>
            <artifactId>geoserver-managerartifactId>
            <version>1.7.0-pdok2version>
        dependency>

配置文件：

geoserver:
  #geoserver地址
  url: http://192.168.2.4:9081/geoserver
  #用户名
  username: admin
  #密码
  password: geoserver
  #工作区
  shpworkspace: ksp
  #数据存储
  shpstorename: frm
  imageworkspace: image
localdir:
  style: protectedAreaGnfq

实现代码：

@Component
public class GeoServer {

    private static Logger logger = LoggerFactory.getLogger(GeoServer.class);

    /**

     */
    private static String url;

    }

    }

        GeoServer.geoPassword = geoPassword;
    }

    @Value("${geoserver.shpworkspace}")
    public void setShpWorkspace(String shpWorkspace) {
        GeoServer.shpWorkspace = shpWorkspace;
    }

    @Value("${geoserver.shpstorename}")
    public void setShpStorename(String shpStorename) {
        GeoServer.shpStorename = shpStorename;
    }

    @Value("${geoserver.imageworkspace}")
    public void setImageWorkspace(String imageWorkspace) {
        GeoServer.imageWorkspace = imageWorkspace;
    }

    @Value("${localdir.style}")

    }

3.成功发布后登录geoserver查看图层

点击左侧Layer Preview，再点击图层对应的OpenLayers
