使用ZipOutputStream类批量压缩文件zip

postmen参数：

{"url":"D:\\2\\档案类型\\清产核资\\清产核资报表\\469005\\测试表.xls,D:\\2\\档案类型\\清产核资\\清产核资报表\\469005\\资产量化表.xls"}

Controller代码：

  public static void generateZip(OutputStream os,@RequestBody Map path) throws Exception {
    String url = path.get("url").toString();//获取参数，参数为要被压缩的文件url
     ZipOutputStream out = null;
     String[] arr = url.split(",");//将要被压缩多个文件utl分切成字符串数组
      try {
        byte[] buffer = new byte[1024];
        out = new ZipOutputStream(os); 
        for (int i=0;i<arr.length;i++) {
          String fileurl = arr[i];
          File file = new File(fileurl);
          FileInputStream fis = new FileInputStream(file);
          out.putNextEntry(new ZipEntry(file.getName()));
          int len;//读入需要下载的文件的内容，打包到zip文件
          while ((len = fis.read(buffer)) != -1) {
            out.write(buffer, 0, len);
          }
          out.flush();
          out.closeEntry();
          fis.close();
        }
      } catch (Exception e) {
          e.printStackTrace();
      } finally {
          if (out != null) {
            out.close();
          }
      }
  }
