Zip4j no error，extract all失败，即使会出现错误

Question

我使用zip4j解压由密码保护的包(AES-256)。我的问题不是代码不工作，而是当密码与.zip上的实际密码不匹配时，它不会抛出任何错误。

.zip的口令为123，对于zip4j，我将口令设置为123456789。所以他不能全部提取出来。我期待一个错误或任何消息，它不能提取。实际情况是，他没有提取它，但没有异常或错误消息，什么都没有。

你知道我该怎么检查提取是否成功吗？

 protected void unpackZip(String destinationPath, String archivePath) throws InterruptedException {
    int onChange = 0;

    try {
        ZipFile zipFile = new ZipFile( archivePath );

        zipFile.setRunInThread( true );

        if (zipFile.isEncrypted()) {
            zipFile.setPassword( "123456789");
        }

        zipFile.extractAll( destinationPath );

        // http://www.lingala.net/zip4j/forum/index.php?topic=68.0
        ProgressMonitor progressMonitor = zipFile.getProgressMonitor();

        while (progressMonitor.getState() == ProgressMonitor.STATE_BUSY) {
            // To get the percentage done
            if (onChange != progressMonitor.getPercentDone()) {
                onChange = progressMonitor.getPercentDone();
                sendWebStatusUiMessage( "Extracted : " + onChange + "% ", "update" );
            }
            try {
                Thread.sleep( 1000 );
            } catch (Exception e) {

            }


        }
    } catch (ZipException e) {
        e.printStackTrace();
    }

}

这个答案有点晚了，但以防对任何人都有用：

在线程模式下运行zip4j时，必须在while循环之后检查任务执行和异常(如果出错)的状态。

while (progressMonitor.getState() == ProgressMonitor.STATE_BUSY) {
    // To get the percentage done
    if (onChange != progressMonitor.getPercentDone()) {
        onChange = progressMonitor.getPercentDone();
        sendWebStatusUiMessage( "Extracted : " + onChange + "% ", "update" );
    }
    try {
        Thread.sleep( 1000 );
    } catch (Exception e) {

    }
}

if (progressMonitor.getResult().equals(ProgressMonitor.Result.SUCCESS)) {
  System.out.println("Successfully added folder to zip");
} else if (progressMonitor.getResult().equals(ProgressMonitor.Result.ERROR)) {
  System.out.println("Error occurred. Error message: " + progressMonitor.getException().getMessage());
} else if (progressMonitor.getResult().equals(ProgressMonitor.Result.CANCELLED)) {
  System.out.println("Task cancelled");
}
