最近接觸到一個(gè)需求要求壓縮導(dǎo)出文件，于是乎便要致力于研究一下工具類啦，故也誕生了此篇文章。下面代碼中，溪源也將import導(dǎo)入的依賴也貼出來(lái)了，避免大家引入錯(cuò)誤。

import org.apache.commons.io.FileUtils;import org.apache.commons.io.IOUtils;import javax.servlet.http.HttpServletResponse;import java.io.*;import java.text.SimpleDateFormat;import java.util.Date;import java.util.zip.ZipEntry;import java.util.zip.ZipOutputStream;/** * @author wx * @date 2020/10/29 5:19 下午 */public class FileZipUtil { private static void handlerFile(ZipOutputStream zip, File file, String dir) throws Exception { //如果當(dāng)前的是文件夾，則進(jìn)行進(jìn)一步處理 if (file.isDirectory()) { //得到文件列表信息 File[] fileArray = file.listFiles(); if (fileArray == null) {return; } //將文件夾添加到下一級(jí)打包目錄 zip.putNextEntry(new ZipEntry(dir + '/')); dir = dir.length() == 0 ? '' : dir + '/'; //遞歸將文件夾中的文件打包 for (File f : fileArray) {handlerFile(zip, f, dir + f.getName()); } } else { //當(dāng)前的是文件，打包處理 //文件輸入流 BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file)); ZipEntry entry = new ZipEntry(dir); zip.putNextEntry(entry); zip.write(FileUtils.readFileToByteArray(file)); IOUtils.closeQuietly(bis); zip.flush(); zip.closeEntry(); } } private static byte[] createZip(String sourceFilePath) throws Exception{ ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); ZipOutputStream zip = new ZipOutputStream(outputStream); //將目標(biāo)文件打包成zip導(dǎo)出 File file = new File(sourceFilePath); handlerFile(zip, file,''); IOUtils.closeQuietly(zip); return outputStream.toByteArray(); } public static void exportZip(HttpServletResponse response, String sourceFilePath) { //文件名以時(shí)間戳作為前綴 SimpleDateFormat sdf = new SimpleDateFormat('yyyyMMddHHmmss'); String filePrefix = sdf.format(new Date()); String downloadName = filePrefix + '.zip'; //將文件進(jìn)行打包下載 try { OutputStream out = response.getOutputStream(); //接收壓縮包字節(jié) byte[] data = createZip(sourceFilePath); response.reset(); response.addHeader('Access-Control-Allow-Origin', '*'); response.setHeader('Access-Control-Expose-Headers', '*'); response.setHeader('Content-disposition', 'attachment;filename*=utf-8’’' + downloadName); response.addHeader('Content-Length', '' + data.length); response.setContentType('application/octet-stream;charset=UTF-8'); IOUtils.write(data, out); out.flush(); out.close(); } catch (Exception e) { e.printStackTrace(); } }}

客戶端調(diào)用方法：

@GetMapping('/exportFile') public Result exportFile(HttpServletResponse response) { //第二個(gè)參數(shù)為：要壓縮文件的地址 FileZipUtil.exportZip(response, '/Users/Downloads'); }

到此這篇關(guān)于Java實(shí)現(xiàn)導(dǎo)出ZIP壓縮包的方法的文章就介紹到這了,更多相關(guān)Java導(dǎo)出ZIP壓縮包內(nèi)容請(qǐng)搜索好吧啦網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持好吧啦網(wǎng)！
