有一個朋友問我改怎麼做，到網上搜了一下，果然有類似的文章及大神解決了此類難題，現將程式碼及所需的jar包附上，供大家使用

package test1;  

import java.io.File;  

import nochump.util.extend.ZipOutput;  

import com.training.commons.file.FileUtils;  

public class ZipFileWithPw {  
    public static void main(String[] args){  
<span style="white-space: pre;"
 
>    </span>final String zipDir = "d:\\backupDB";  
        final String EncryptZipFile = "d:\\backupDB\\db_user.zip";  
        final String password = "123456";  

        System.out.println("===== 加密 =====");  
        File file = new File(zipDir);  
        byte[] zipByte = ZipOutput.getEncryptZipByte(file.listFiles(), password);  
        FileUtils.writeByteFile(zipByte, new
 
 File(EncryptZipFile));  
        System.out.println("===== Encrypt Success =====");  

    }  
}
