//设置压缩级别
//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);

//设置压缩文件加密
parameters.setEncryptFiles(true);

//设置加密方法
parameters.setEncryptionMethod(Zip4jConstants.ENC_METHOD_AES);

//设置aes加密强度
parameters.setAesKeyStrength(Zip4jConstants.AES_STRENGTH_256);

//设置密码
parameters.setPassword("wzx");

//添加文件到压缩文件
zipFile.addFiles(files, parameters);
