h5上传图片压缩包服务端解压并上传图片

CMS后台有上传多个图片的需求，多个图片上传也一样麻烦。就想做个上传压缩包服务端解压上传的东西。

页面

使用h5的上传api

      /*
             *
             * name: 上传字段标示
             postUrl: 文件数据处理URL
             onClientAbort: 读取操作终止时调用
             onClientError: 出错时调用
             onClientLoad: 读取操作成功时调用
             onClientLoadEnd: 无论是否成功，读取完成时调用。通常在onload和onerror后调用
             onClientLoadStart: 读取将要开始时调用
             onClientProgress: 数据在读取过程中周期性调用
             onServerAbort: post操作结束时调用
             onServerError: 错误发生时调用
             onServerLoad: post操作成功时调用
             onServerLoadStart: post数据将要开始时调用
             onServerProgress: 数据正在被post的过程中周期性调用
             onServerReadyStateChange: 一个javascript功能对象无论任何时候readyState属性变化时调用。callback由用户界面现成调用。
             *

用了一些美化过的弹窗控件

SweetAlert

引入js就行了。

后台模板之前常用ACE的。
扣下来改吧改吧。

服务端

服务端用的Java写的。

    @Transactional
    @RequestMapping(value = "uploadZip", method = RequestMethod.POST)
    public Map<String, Object> uploadZip(HttpServletRequest request) throws Exception {

        Map<String, Object> result = new HashMap<>();
        User user = GrantedFilter.threadLocal.get();
        final Integer userId = user.getId();

        Uploader uploader = new Uploader(request);
        // 解压
        final File[] fileList = uploader.uploadMaterialZip();
        // 有时候压缩会出问题  Mac 和 Windows 
        if (fileList.length < 1 || fileList.length>1?fileList[1].isDirectory():fileList[0].isDirectory()) {
            File f = null;
            try {
                f = new File(fileList[0].getParent());
                deleteFile(f);
            } catch (Exception e) {

            }
            result.put("code", "400");
            return result;
        } else {
            threadPoolTaskExecutor.execute(new Runnable() {
                @Override
                public void run() {
                    String temp = fileList[0].getParent();
                    for (File file : fileList) {
                        if (file.getName().endsWith(".gif")||file.getName().endsWith(".GIF")) {
                            UFileRequest uFileRequest = new UFileRequest();
                            String gifKey = RandomStringUtils.randomAlphanumeric(32) + ".gif";

                            uFileAPI.putFile(uFileRequest);
                            String url = uFileAPI.getDownloadUrl(uFileRequest, 0, false);
                            MaterialRaw materialRaw = new MaterialRaw();
                            materialRaw.setTag("3");

                    deleteFile(f);
                }
            });
        }
        result.put("code", "200");
        return result;
    }

解压的Util类

    public File[] uploadMaterialZip() throws Exception {
        originalName = request.getHeader("X-File-Name");
        type = FileUtil.getFileExt(originalName);
        if (!".zip".equals(type.toLowerCase())) {
            throw new BadRequestException("格式错误！");
        }
        if (request.getContentLength() / 1024000 > 100) {
            throw new BadRequestException("文件太大！");
        }
        fileName = Util.RunTimeSequence() + type;
        path = DateUtil.zipDateFormat(new Date()) + File.separator + fileName;
        File file = new File(savePath + File.separator + path);
        file.getParentFile().mkdirs();
        try (InputStream is = request.getInputStream();
             FileOutputStream fos = new FileOutputStream(file)) {
            IOUtils.copy(is, fos);
            size = file.length();
        }
        String str = savePath + File.separator + System.currentTimeMillis();
        File dir = new File(str);
        if (!dir.exists() || !dir.isDirectory()) {
            dir.mkdirs();
        }
        String temp = savePath + File.separator + DateUtil.zipDateFormat(new Date()) + File.separator;
        // 加压的工具类
        DeCompressUtil.deCompress(savePath + File.separator + path, str, temp);
        File gifFile = new File(str);
        File[] fileList = gifFile.listFiles();
