一、压缩文件
压缩前效果：
压缩后效果
解压缩输入密码
@Testpublic void createZipFile(){String password = "123456"; // 设置压缩密码 解压的时候需要输入该密码进行解压String filePath = "D:\\app\\SFiles\\toprs\\createfile\\test\\";String sourceFileName = "_6666000001060017_div.csv";File sourceFile = new File(filePath+sourceFileName);String zipFileName = sourceFileName.replace(".csv",".zip");log.info("开始压缩文件,压缩后的文件名为：{}",zipFileName);ZipFile zipFile;try {zipFile = new ZipFile(filePath+zipFileName);File deleteFile = zipFile.getFile();if (deleteFile.exists()) {deleteFile.delete();}ZipParameters parameters = new ZipParameters();parameters.setCompressionMethod(P_DEFLATE);parameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_NORMAL);parameters.setEncryptFiles(true);parameters.setEncryptionMethod(Zip4jConstants.ENC_METHOD_AES);parameters.setAesKeyStrength(Zip4jConstants.AES_STRENGTH_256);parameters.setPassword(password);zipFile.addFile(sourceFile, parameters);log.info("文件{}压缩成功",sourceFileName);}catch (Exception e){log.info("压缩文件：{}失败",sourceFileName);}}
二、解压文件
public void unzip(String zipFileName, String unPath, String password) throws ZipException {try {ZipFile zipFile = new ZipFile(zipFileName);zipFile.setFileNameCharset("GBK");if (!zipFile.isValidZipFile()) {throw new ZipException("压缩文件不合法,可能被损坏");}File destDir = new File(unPath);if (destDir.isDirectory() && !destDir.exists()) {destDir.mkdir();}if (zipFile.isEncrypted()) {zipFile.setPassword(password.toCharArray());}zipFile.extractAll(unPath);} catch (Exception e) {throw new BizException("解压zip文件失败");}}
