Java使用zip4j加密压缩和解压文件与文件夹

news 2025/7/14 8:47:12

最近项目中有个需求需要对文件夹进行压缩后传输，考虑数据泄露安全性问题，需要对压缩包进行加密，特地查找了下开源压缩加密类库，找到了Java语言开发的zip4j库，觉得挺好用的，在这分享给大家！

Java项目引入使用步骤如下：

1、引入maven依赖

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

2、封装的工具类

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;
