简要说明

利用开源工具geoserver-manager，对postgresql的空间表进行地图服务发布

maven依赖

			<dependency><groupId>com.github.dov-vlaanderen</groupId><artifactId>geoserver-manager</artifactId><version>1.8</version></dependency>

样例代码

封装的入参实体

@Data
public class ReqDTO {/*** 数据源信息，主要包含数据库地址、端口、库名、用户名称、密码，就不详细列出来了*/private DataSourceInfo dataSourceInfo;/*** geoserver站点地址*/private String serverUrl;/*** 站点用户名称*/private String userName;/*** 站点密码*/private String passWord;/*** 工作区名称*/private String workspaceName;/*** 表名*/private String tableName;/*** 样式名称*/private String styleName;/*** 样式文件,若有样式文件,会注册样式*/private MultipartFile styleFile;}

辅助方法

主体发布代码
