Windows下gdal 的 Java 环境配置

曾经终败给现在 2022-10-05 06:44 641阅读 0赞

假设你已经安装好java jdk，并配置好环境变量。  
参考：  
http://trac.osgeo.org/gdal/wiki/GdalOgrInJava  
http://trac.osgeo.org/gdal/wiki/GdalOgrInJavaBuildInstructions（编译java版gdal）

这里采用是编译好的gdal，下载地址：
    http://www.gisinternals.com/release.php
    选择win32/x64版的zip,解压到相关目录下。
    
    下载：release-1928-x64-gdal-3-3-0-mapserver-7-6-3
    
    
    配置java中的jdk library path，
    
    将下载后的D:\tools\release-1928-x64-gdal-3-3-0-mapserver-7-6-3\bin目录下的所有.dll文件 copy 到java/jdk/bin下。
    同时将D:\tools\release-1928-x64-gdal-3-3-0-mapserver-7-6-3\bin\gdal\java目录下的所有.dll文件 copy到/java/jdk/bin下

在IDEA下新建一个maven工程，将解压后的gdal.jar加到library中如图或者添加pom.xml
