如何在jar文件中读取zip文件

Question

我有一个zip文件（在一个jar文件中），我想读取init。我知道我可以使用getResourceAsStream（…）轻松读取txt文件，避免“URI不分层”错误。但现在确定我该如何为zip文件做到这一点。

下面是我的代码，但当我将代码导出到runnable jar并运行它时，它会抛出“URI非层次错误”。

URL fileLocation = ChemicalSynonyms.class.getClassLoader().getResource("sciome/workbench/resources/chemicalSynonym/" + strFileName);
        File file = new File(fileLocation.toURI());

        // it is a zip file
        ZipFile zipFile = new ZipFile(file);
        Enumeration<? extends ZipEntry> entries = zipFile.entries();
        ZipEntry entry = entries.nextElement();
        InputStream is = zipFile.getInputStream(entry);
        BufferedReader buf = new BufferedReader(new InputStreamReader(is));
        String lineJustFetched = null;
        String[] wordsArray;

        // read each line
        lineJustFetched = buf.readLine();

这可以通过使用扫描仪来完成。例子：

        InputStream is = MainClass.class.getClassLoader().getResourceAsStream(file location with zip file name);
        ZipInputStream zis = new ZipInputStream(is);
        ZipEntry ze = zis.getNextEntry();
        Scanner sc = new Scanner(zis);

        String[] wordsArray;
        while (sc.hasNextLine())
        {
           ....
        }
