Java中受密码保护的zip文件

尝试以下基于以下代码Zip4j：

import net.lingala.zip4j.core.ZipFile;import net.lingala.zip4j.exception.ZipException;import net.lingala.zip4j.model.ZipParameters;import net.lingala.zip4j.util.Zip4jConstants;import org.apache.commons.io.FilenameUtils;import java.io.File;public class Zipper{    private String password;    private static final String EXTENSION = "zip";    public Zipper(String password)    {        this.password = password;    }    public void pack(String filePath) throws ZipException    {        ZipParameters zipParameters = new ZipParameters();        zipParameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE);        zipParameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_ULTRA);        zipParameters.setEncryptFiles(true);        zipParameters.setEncryptionMethod(Zip4jConstants.ENC_METHOD_AES);        zipParameters.setAesKeyStrength(Zip4jConstants.AES_STRENGTH_256);        zipParameters.setPassword(password);        String baseFileName = FilenameUtils.getbaseName(filePath);        String destinationZipFilePath = baseFileName + "." + EXTENSION;        ZipFile zipFile = new ZipFile(destinationZipFilePath);        zipFile.addFile(new File(filePath), zipParameters);    }    public void unpack(String sourceZipFilePath, String extractedZipFilePath) throws ZipException    {        ZipFile zipFile = new ZipFile(sourceZipFilePath + "." + EXTENSION);        if (zipFile.isEncrypted())        { zipFile.setPassword(password);        }        zipFile.extractAll(extractedZipFilePath);    }}

FilenameUtils

Apache Commons IO

用法示例：

public static void main(String[] arguments) throws ZipException{    Zipper zipper = new Zipper("password");    zipper.pack("encrypt-me.txt");    zipper.unpack("encrypt-me", "D:\");}
