Question

我正在使用Eclipse Java EE，Maven和Geotools开发一个项目。这是我要谈论的代码的一部分：

Map connectionParameters = new HashMap();
// Connection parameters
connectionParameters.put(WFSDataStoreFactory.URL.key, getCapabilities );
connectionParameters.put(WFSDataStoreFactory.PROTOCOL.key, false );
connectionParameters.put(WFSDataStoreFactory.LENIENT.key, true );
connectionParameters.put(WFSDataStoreFactory.MAXFEATURES.key, 30);
connectionParameters.put(WFSDataStoreFactory.TIMEOUT.key, 600000);
try { // The WFSDataStoreFactory dsf is already created before
    WFSDataStore dataStore = dsf.createDataStore(connectionParameters);
    // We get the source and then the features from it
    SimpleFeatureSource source = dataStore.getFeatureSource("gmgml_AREAOBRA");
    FeatureCollection<SimpleFeatureType, SimpleFeature> fc = source.getFeatures();
    // We try to go one by one and print to see if it really exists
    while(fc.features().hasNext()){
        SimpleFeature sf = fc.features().next();
        System.out.println(sf.getAttribute("IDOBRA")); } // It crashes

问题在于我读了关于崩溃后给我的下一个错误的每篇文章：

但我无法找到解决问题的具体方法。
