文件夹加密不起作用（包括演示）

Question

这个简单的文件夹 encryption/compression 失败了。该文件夹仅包含子文件夹和文本文件，但加密 returns false。知道为什么吗？

import net.lingala.zip4j.ZipFile;
import net.lingala.zip4j.exception.ZipException;
import net.lingala.zip4j.model.ZipParameters;
import net.lingala.zip4j.model.enums.AesKeyStrength;
import net.lingala.zip4j.model.enums.CompressionLevel;
import net.lingala.zip4j.model.enums.CompressionMethod;
import net.lingala.zip4j.model.enums.EncryptionMethod;
import java.io.File;

public class Demo_ZipEncryptFolderOnly {
    public static void main(String[] args) throws ZipException {
        ZipParameters zipParameters = new ZipParameters();
        zipParameters.setEncryptFiles(true);
        zipParameters.setCompressionMethod(CompressionMethod.DEFLATE);
        zipParameters.setCompressionLevel(CompressionLevel.NORMAL);
        zipParameters.setEncryptionMethod(EncryptionMethod.AES);
        zipParameters.setAesKeyStrength(AesKeyStrength.KEY_STRENGTH_256);
        ZipFile zipFile = new ZipFile("C:\Users\me\Desktop\Folder.zip", "password".toCharArray());
        zipFile.addFolder(new File("C:\Users\me\Desktop\Folder"));
        System.out.println("Encrypted: "+zipFile.isEncrypted());
    }
}

Maven:

<dependency>
     <groupId>net.lingala.zip4j</groupId>
     <artifactId>zip4j</artifactId>
     <version>2.8.0</version>
</dependency>

要加密的文件夹：

Answer 1

您忘记将 zipParameters 作为 zipFile.addFolder() 调用中的第二个参数传递。如果这是固定的，它将起作用（s. 也是 zip4j docs）：

zipFile.addFolder(new File("C:\Users\me\Desktop\Folder"), zipParameters);
