我正在使用Java編寫的Web地圖服務以及使用GeoTools庫。我的目標是使數據解析JSON格式，所以我使用的是form Unsupported GeoTools。這是parsingJSON方法，它在輸入文件並返回作爲輸出的文件的FeatureCollection功能的路徑：Java Servlet：使用Geotools解析geo JSON
public FeatureCollection parsingJSON(String path) throws FileNotFoundException, IOException, ParseException {
System.out.println("INTO PARSINGJSON");
JSONParser parser = new JSONParser();
File f = new File(path);
System.out.println("complete path file --->" + f.getAbsolutePath());
Object obj = parser.parse(new java.io.FileReader(path));
FeatureJSON fJSON = new FeatureJSON();
FeatureCollection fc = fJSON.readFeatureCollection(obj.toString());
return fc;
}
當我通過傳遞文件的路徑運行的代碼，使我這個例外：

我要澄清的是我導入庫正常json-simple-1.1，我有以下的pom.xml：

我不得不把庫lib目錄中。 [已解決] – maxada
如果您的pom正確，mvn war應該爲您做這件事 –
我無法更正pom.xml文件。不幸的是，我正在開展另一個人發起的項目，這是我可以做的最好的，或者手動添加它們。有人知道告訴我如何調整pom.xml文件嗎？ – maxada
