Question

我正在尝试将JWKTL库安装到Java项目中。 JWKTL Getting started

现在我按照描述下载了转储文件，并将其解析为一个新目录。

我的代码是：

package main;

import java.io.File;
import java.util.List;

import de.tudarmstadt.ukp.jwktl.JWKTL;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryEdition;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryEntry;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryPage;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryRelation;
import de.tudarmstadt.ukp.jwktl.api.PartOfSpeech;
import de.tudarmstadt.ukp.jwktl.api.RelationType;


public class Main {

    final static String PATH_TO_DUMP_FILE = "/GetWords/enwiktionary-20160601-pages-articles-multistream.xml";
    final static String TARGET_DIRECTORY = "/GetWords/";
    final static boolean OVERWRITE_EXISTING_FILES = true;
    /**
     * Simple example which parses an English dump file and prints the entries for the word <i>Wiktionary</i>
     * @param args name of the dump file, output directory for parsed data, ISO language code of the Wiktionary entry language (en/de), boolean value that specifies if existing parsed data should be deleted
     */
        public static void main(String[] args) throws Exception {
            File dumpFile = new File(PATH_TO_DUMP_FILE);
              File outputDirectory = new File(TARGET_DIRECTORY);
              boolean overwriteExisting = OVERWRITE_EXISTING_FILES;

              JWKTL.parseWiktionaryDump(dumpFile, outputDirectory, overwriteExisting);

              IWiktionaryEdition wkt = JWKTL.openEdition(TARGET_DIRECTORY);

              //TODO: Query the data you need.

              // Close the database connection.
              wkt.close();
}
}

但是当我尝试输入dump_file时，行IWiktionaryEdition wkt = JWKTL.openEdition(TARGET_DIRECTORY);会抛出错误：The method openEdition(File) in the type JWKTL is not applicable for the arguments (String) 的java.io.File

程序抛出以下错误：

    ... 4 more

有人知道如何解决这个问题吗？

我在Eclipse Mars中使用Java 8。

我安装了这些库：

jwktl-1.0.1.jar
JE-6.4.25.jar
阿帕奇-ANT-1.8.2.jar

谢谢！

Answer 1

我解决了...... 这太简单了：

结论是：

File f = new File(TARGET_DIRECTORY);

IWiktionaryEdition wkt = JWKTL.openEdition(f);

祝你好运！
