java.io.FileNotFoundException - zip4j

Question

我尝试创建一个简单的 Java 程序，该程序尝试使用 zip4j 解压缩 zip 文件。但是每次我得到一个java.io.FileNotFoundException。我不知道为什么，因为路径存在并且文件可以为 java 写。 zip 文件也没有损坏。

我使用lates zip4j 库运行最新的jdk。一切都正确实施。我试图解压缩一个只包含一个 jar 的 zip 并且它有效。但是包含更多文件的 zip 失败了。

我是 Java 新手，也是使用 zip4j 的新手。

String enviorment = new File(".").getCanonicalPath();
unzip(enviorment + "/../WITCLASS/cache/dokumentation.zip", enviorment + "/../WITCLASS/cache/");

.zip 文件包括一些 .html 和 .js 文件

private static void unzip(String zipFilePath, String destDir) {
        String source = zipFilePath;
        String destination = destDir;
        String password = "";

        try {
            ZipFile zipFile = new ZipFile(source);
            if (zipFile.isEncrypted()) {
                zipFile.setPassword(password);
            }
            zipFile.extractAll(destination);
        } catch (ZipException e) {
            e.printStackTrace();
            System.out.println(e);
        }
    }

预期的输出是：所有文件都成功解压。

但我只有：

我了解如何解压缩的来源： What is a good Java library to zip/unzip files?

Answer 1

我找到了一个简单的解决方法来解压文件@What is a good Java library to zip/unzip files?

unzip("path/to/SORUCE.zip", "path/to/destinationfolder");

public void unzip(String source, String dest) throws IOException {
    java.util.zip.ZipFile zipFile = new ZipFile(source);
    try {
        Enumeration<? extends ZipEntry> entries = zipFile.entries();
        while (entries.hasMoreElements()) {
            ZipEntry entry = entries.nextElement();
            File entryDestination = new File(dest, entry.getName());
            if (entry.isDirectory()) {
                entryDestination.mkdirs();
            } else {
                entryDestination.getParentFile().mkdirs();
                InputStream in = zipFile.getInputStream(entry);
                OutputStream out = new FileOutputStream(entryDestination);
                IOUtils.copy(in, out);
                IOUtils.closeQuietly(in);
                out.close();
            }
        }
    } finally {
        zipFile.close();
    }
}
