SHP开放：数据存储DataStoreFactorySpi不是ImageIO SPI类

Question

在学校我必须创建一个API，我需要在shapefile中使用一些几何体。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();


}

我犯了这个错误：

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 java.desktop/javax.imageio.spi.ServiceRegistry.<init>(ServiceRegistry.java:140)

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

数据存储区不希望被创建，我不明白它来自哪里......你能帮帮我吗？提前致谢 ..

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

TL; DR：org.geotools.factory.FactoryRegistry扩展了javax.imageio.spi.ServiceRegistry，但是在Java 9上，后者如果被非JDK类扩展则抛出异常;这打破了Java 9上的GeoTools

您需要将GeoTools版本升级到Java 9兼容（首选），或将Java“降级”为Java 8。
