首先創(chuàng)建一個(gè)工具類(lèi)，定義好接口，這里的參數(shù)
1：fileList：多個(gè)文件的path+name
2： zipFileName：壓縮后的文件名

下面是代碼，注釋已經(jīng)很詳細(xì)了

public class ZIPUtil {
    
    public static String createZipFile(ArrayList fileList, String zipFileName) {

        if(fileList == null || fileList.size() == 0 || CommonUtil.isEmpty(zipFileName)){
            return null;
        }
        
        //構(gòu)建壓縮文件File
        File zipFile = new File(zipFileName);
        //初期化ZIP流
        ZipOutputStream out = null;

        try{
            //構(gòu)建ZIP流對(duì)象
            out = new ZipOutputStream(new FileOutputStream(zipFile));
            //循環(huán)處理傳過(guò)來(lái)的集合
            for(int i = 0; i < fileList.size(); i++){
                //獲取目標(biāo)文件
                File inFile = new File(fileList.get(i));
                if(inFile.exists()){
                     //定義ZipEntry對(duì)象
                     ZipEntry entry = new ZipEntry(inFile.getName());
                     //賦予ZIP流對(duì)象屬性
                     out.putNextEntry(entry);
                     int len = 0 ;
                     //緩沖
                     byte[] buffer = new byte[1024];
                     //構(gòu)建FileInputStream流對(duì)象
                     FileInputStream fis;
                     fis = new FileInputStream(inFile);
                     while ((len = fis.read(buffer)) > 0) {
                         out.write(buffer, 0, len);
                         out.flush();
                     }
                     //關(guān)閉closeEntry
                     out.closeEntry();
                     //關(guān)閉FileInputStream
                     fis.close();
                }
            }
        }catch (IOException e) {
            e.printStackTrace();
        }finally{
             try {
                 //最后關(guān)閉ZIP流
                 out.close();
             } catch (IOException e) {
                 e.printStackTrace();
             }
        }


        return zipFileName;

    }
