使用Gdal转换Cad为Shp

windows环境下安装gdal

• 从官网下载gdal，并将相关dll文件拷贝至C:\Windows\System32目录下
• 在springboot项目的resources目录下新增lib目录，将gdal.jar拷贝lib目录
• 在pom.xml文件中引入外部依赖

<dependency>
            <groupId>gdal</groupId>
            <artifactId>gdal</artifactId>
            <version>0.0.1</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/lib/gdal.jar</systemPath>
</dependency>

代码示例

package com.example.demo.gis;

import org.gdal.gdal.gdal;
import org.gdal.ogr.DataSource;
import org.gdal.ogr.Driver;
import org.gdal.ogr.Layer;
import org.gdal.ogr.ogr;
