更新参数中的密码设置和压缩文件创建方法。

您可以使用 Zip4j 库 http://www.lingala.net/zip4j/download.php

如果你想要 AES 加密，你也可以使用以下代码

// Initiate ZipFile object with the path/name of the zip file.
            ZipFile zipFile = new ZipFile("c:\\ZipTest\\AddFilesWithAESZipEncryption.zip");

// Build the list of files to be added in the array list
            // Objects of type File have to be added to the ArrayList
            ArrayList filesToAdd = new ArrayList();
            filesToAdd.add(new File("c:\\ZipTest\\sample.txt"));
            filesToAdd.add(new File("c:\\ZipTest\\myvideo.avi"));
            filesToAdd.add(new File("c:\\ZipTest\\mysong.mp3"));

            // Initiate Zip Parameters which define various properties
            ZipParameters parameters = new ZipParameters();
            parameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE); // set compression method to deflate compression

 //DEFLATE_LEVEL_FASTEST     - Lowest compression level but higher speed of compression
            //DEFLATE_LEVEL_FAST        - Low compression level but higher speed of compression
            //DEFLATE_LEVEL_NORMAL  - Optimal balance between compression level/speed
            //DEFLATE_LEVEL_MAXIMUM     - High compression level with a compromise of speed
            //DEFLATE_LEVEL_ULTRA       - Highest compression level but low speed
            parameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_NORMAL);

            //Set the encryption flag to true
            parameters.setEncryptFiles(true);

            //Set the encryption method to AES Zip Encryption
            parameters.setEncryptionMethod(Zip4jConstants.ENC_METHOD_AES);

            //AES_STRENGTH_128 - For both encryption and decryption
            //AES_STRENGTH_192 - For decryption only
            //AES_STRENGTH_256 - For both encryption and decryption
            //Key strength 192 cannot be used for encryption. But if a zip file already has a
            //file encrypted with key strength of 192, then Zip4j can decrypt this file
            parameters.setAesKeyStrength(Zip4jConstants.AES_STRENGTH_256);

            //set password
            parameters.setPassword("your password here");

// Now add files to the zip file
            // Note: To add a single file, the method addFile can be used
            // Note: If the zip file already exists and if this zip file is a split file
            // then this method throws an exception as Zip Format Specification does not 
            // allow updating split zip files
            zipFile.addFiles(filesToAdd, parameters);

setEncryptionMethod() 将类型设置为您想要的加密。 setAesKeyStrength() 设置加密算法的强度。
