POI导出图片到excel

1.需求: 导出图片到excel中

2. 问题:图片是存在图片服务器上,不能直接像读取本地图片那样读取图片

3.  解决方案参考网上

 //  插入图片
        String shopPic = storeFindVo.getShopPic();
        int num = 0;
        if (shopPic != null){
            //获取服务器地址
            String filePath = SystemConstants.getPtdImageUrl();
            String[] picList = shopPic.split(",");
            for (int i=0;i<picList.length;i++){
                try {
                    byte[] data = {};
                    URL url = new URL(filePath + picList[i]);
                    //打开连接
                    HttpURLConnection conn = (HttpURLConnection)url.openConnection();
                    //设置请求方式为"GET"
                    conn.setRequestMethod("GET");
                    //超时响应时间为5秒
                    conn.setConnectTimeout(5 * 1000);
                    //通过输入流获取图片数据
                    InputStream inStream = conn.getInputStream();
                    data = readInputStream(inStream);
                    if (i == 0){
                        exportMap.put("shopPic",data);
                    }else{
                        exportMap.put(""+num,data);
                        if (!arrayList.contains(""+num)){
                            arrayList.add(""+num);
                        }
                    }
                    num ++;
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }else {
            exportMap.put("shopPic","");
        }
