java - SHP 打开 : datastore DataStoreFactorySpi is not an ImageIO SPI class

Question

在学校，我必须创建一个 API，其中我需要在 shapefile 中包含一些几何图形。我使用 geotools librairie 打开 shapefile。这是我的代码:

public class main {

    public static void main(String[] args) throws Exception{
        String filepath = "SHP_test/testSHPindex.shp";
        File shp = new File(filepath);

        Map<String, URL> map = new HashMap<String, URL>();
        map.put( "url", shp.toURI().toURL() );
        DataStore dataStore = DataStoreFinder.getDataStore(map);


        SimpleFeatureSource featureSource = dataStore.getFeatureSource(dataStore.getTypeNames()[0]);        
        SimpleFeatureCollection collection = featureSource.getFeatures();


}

我得到这个错误:

Exception in thread "main" java.lang.IllegalArgumentException: org.geotools.data.DataStoreFactorySpi is not an ImageIO SPI class
    at java.desktop/javax.imageio.spi.ServiceRegistry.checkClassAllowed(ServiceRegistry.java:745)

    at org.ensg.projetperso.llb.maven.api.spatialindexingtest.testshapefile.main.main(main.java:30)

不想创建数据存储，我不明白它来自哪里......你能帮我吗 ？提前致谢..

劳拉

这似乎是 GeoTools 中的一个已知问题，请参阅 FactoryRegistry Refactoring for Java 9 Compatibility .来自问题:

TL;DR: org.geotools.factory.FactoryRegistry extends javax.imageio.spi.ServiceRegistry, but on Java 9 the latter throws an exception if extended by non-JDK classes; this breaks GeoTools on Java 9

您需要将您的 GeoTools 版本升级到与 Java 9 兼容的版本(首选)，或者将您的 Java“降级”到 Java 8。
