一、普通方式
package com.hebta.source.code.util;import java.io.*;import java.util.zip.ZipEntry;import java.util.zip.ZipOutputStream;public class ZipUtils { public String createZip(String[] files) { String zipFileName = "zipName.zip"; // zipName为上一步文件打包zip时传入的zipName File zipFile = new File("/woke/file/" + zipFileName); if (!zipFile.getParentFile().exists()) { zipFile.getParentFile().mkdirs(); } if (!zipFile.exists()) { try { zipFile.createNewFile(); } catch (IOException e) { e.printStackTrace(); } } zip(files, zipFile); return zipFileName; } public void zip(String[] files, File zipFile) { FileInputStream fileInputStream = null; FileOutputStream fileOutputStream = null; ZipOutputStream zipOutputStream = null; BufferedInputStream bufferInputStream = null; try { // zipFileName为压缩文件的名称（xx.zip），首先在某个目录下（C:/temp/路径可以根据自己的需求进行修改）创建一个.zip结尾的文件 fileOutputStream = new FileOutputStream(zipFile); zipOutputStream = new ZipOutputStream(new BufferedOutputStream(fileOutputStream)); // 创建读写缓冲区 byte[] bufs = new byte[1024 * 10]; for (String file : files) { File voiceFile = new File(file); if (voiceFile.exists()) { ZipEntry zipEntry; // 压缩文件下的目录分级，如果不分目录可以直接用fileName.文件后缀 zipEntry = new ZipEntry("path/folderName/fileName." + getFileExtension(voiceFile)); // 创建ZIP实体，并添加进压缩包 zipOutputStream.putNextEntry(zipEntry); // 读取待压缩的文件并写进压缩包里 fileInputStream = new FileInputStream(voiceFile); bufferInputStream = new BufferedInputStream(fileInputStream, 1024 * 10); int read = 0; while ((read = bufferInputStream.read(bufs, 0, 1024 * 10)) != -1) { zipOutputStream.write(bufs, 0, read); } } } } catch (IOException e) { e.printStackTrace(); } finally { try { if (bufferInputStream != null) { bufferInputStream.close(); } if (zipOutputStream != null) { zipOutputStream.close(); } } catch (IOException e) { e.printStackTrace(); } } } private static String getFileExtension(File file) { String fileName = file.getName(); if (fileName.lastIndexOf(".") != -1 && fileName.lastIndexOf(".") != 0) return fileName.substring(fileName.lastIndexOf(".") + 1); else return " "; }}二、使用zip4j方式
引入jar：
net.lingala.zip4j zip4j 2.8.0 代码块：
package com.hebta.source.code.util;import lombok.extern.slf4j.Slf4j;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.EncryptionMethod;import java.io.File;import java.util.ArrayList;import java.util.List;@Slf4jpublic class ZipUtils { public static void createZip(List files, String zipName, String pwd) { ZipParameters zipParameters = new ZipParameters(); zipParameters.setEncryptFiles(true); zipParameters.setEncryptionMethod(EncryptionMethod.AES); // Below line is optional. AES 256 is used by default. You can override it to use AES 128. AES 192 is supported only for extracting. zipParameters.setAesKeyStrength(AesKeyStrength.KEY_STRENGTH_256); List filesToAdd = new ArrayList<>(); for (String file : files) { filesToAdd.add(new File(file)); }// 将文件夹添加到压缩文件// new ZipFile("filename.zip").addFolder(new File("/users/some_user/folder_to_add")); ZipFile zipFile = new ZipFile(zipName, pwd.toCharArray()); try { zipFile.addFiles(filesToAdd, zipParameters); } catch (ZipException e) { log.info("生成zip失败：" + e.getMessage()); e.printStackTrace(); } } public static void zipFileWithPwd(String inputFile,String outputFile, String pwd) { // 生成的压缩文件 try { ZipFile zipFile = new ZipFile(outputFile, pwd.toCharArray()); ZipParameters zipParameters = new ZipParameters(); zipParameters.setEncryptFiles(true); zipParameters.setEncryptionMethod(EncryptionMethod.AES); zipParameters.setAesKeyStrength(AesKeyStrength.KEY_STRENGTH_256); // 要打包的文件夹 File currentFile = new File(inputFile); File[] fs = currentFile.listFiles(); // 遍历test文件夹下所有的文件、文件夹 for (File f : fs) { if (f.isDirectory()) { zipFile.addFolder(f, zipParameters); } else { zipFile.addFile(f, zipParameters); } } } catch (ZipException e) { e.printStackTrace(); } }} 来源地址：https://blog.csdn.net/clz979991314/article/details/127849372
