Java使用zip4j加密壓縮和解壓文件與文件夾方式

更新時間：2025年12月27日 14:26:33 作者：棉花糖老丫

文章介紹了如何使用Java的zip4j庫對文件夾進行加密壓縮,并提供了Java項目的引入和使用步驟,包括引入maven依賴、封裝工具類以及測試結(jié)果

1、引入maven依賴

<dependency>
            <groupId>net.lingala.zip4j</groupId>
            <artifactId>zip4j</artifactId>
            <version>2.11.5</version>
 </dependency>

2、封裝的工具類

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 org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
