总结一下，关于Java下载zip文件并导出的方法，浏览器导出。

　　　　　String downloadName = "下载文件名称.zip";        downloadName = BrowserCharCodeUtils.browserCharCodeFun(request, downloadName);//下载文件名乱码问题解决                //将文件进行打包下载        try {            OutputStream out = response.getOutputStream();            byte[] data = createZip("/fileStorage/download");//服务器存储地址            response.reset();            response.setHeader("Content-Disposition","attachment;fileName="+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();        }

 

 

//获取下载zip文件流

public byte[] createZip(String srcSource) throws Exception{        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();        ZipOutputStream zip = new ZipOutputStream(outputStream);        //将目标文件打包成zip导出        File file = new File(srcSource);         a(zip,file,"");        IOUtils.closeQuietly(zip);        return outputStream.toByteArray();    }

 

public void a(ZipOutputStream zip, File file, String dir) throws Exception {            //如果当前的是文件夹，则进行进一步处理            if (file.isDirectory()) {                //得到文件列表信息                File[] files = file.listFiles();                //将文件夹添加到下一级打包目录                zip.putNextEntry(new ZipEntry(dir + "/"));                dir = dir.length() == 0 ? "" : dir + "/";                //循环将文件夹中的文件打包                for (int i = 0; i < files.length; i++) {                    a(zip, files[i], dir + files[i].getName());         //递归处理                }            } else {   //当前的是文件，打包处理                //文件输入流               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();            }    }
