一、初试geotools

因为项目需要使用Gis地图，一直学java的，于是找到了geotools，更新还很频繁，那就用他吧，下载了最新版的geotools-23.4-bin，netbeans开发起来，导入java包，按照官网文档Quickstart代码抄过来，期待出界面但是报了一堆错：

//si-units-Java8-7.0.1.jar

//Exception in thread "main" java.lang.NoClassDefFoundError: si/uom/SI

 

//indriya-2.1.1.jar

//Exception in thread "main" java.lang.NoClassDefFoundError: tech/units/indriya/unit/Units

 

//unit-api-1.0.jar

//Exception in thread "main" java.lang.NoClassDefFoundError: javax/measure/spi/SystemOfUnits

 

//uom-lib-common-1.0.2.jar

//Exception in thread "main" java.lang.NoClassDefFoundError: tech/uom/lib/common/function/Nameable

 

//uom-se-1.0.8.jar

//Exception in thread "main" java.lang.NoClassDefFoundError: tec/uom/se/AbstractSystemOfUnits

 

费了好几天时间找了各种版本的jar包，最终如上对应的jar导入后终于可以看到地图界面了。

 

但是还有很多其他错误：

警告: Can't load a service for category "RasterProcess". Cause is "ServiceConfigurationError: org.geotools.process.raster.RasterProcess: Provider org.geotools.process.raster.JiffleProcess could not be instantiated".

java.util.ServiceConfigurationError: org.geotools.process.raster.RasterProcess: Provider org.geotools.process.raster.JiffleProcess could not be instantiated

Caused by: java.lang.NoClassDefFoundError: Could not initialize class javax.media.jai.JAI

网上查了需要安装JAI运行时环境。暂时不安装了，后面再说吧。
