订单 图片（一对多关系）,地址保存在一个字段中（Json数组对象格式）

订单---->图片（一对多关系）,地址保存在一个字段中（Json数组对象格式）
1、前端列表动态添加：
jsp：

2、web后台：
    @RequestMapping(value = "/uploadPhoto", method = RequestMethod.POST)
	@ResponseBody
	public Object uploadPhoto(@RequestParam MultipartFile[] sourceFiles, int type, String orderid,Long id) throws IOException {
		// 更新订单对应的图片
		WLOrder wlOrder = new WLOrder();
		wlOrder.setOrderid(orderid);		
		List strlist=new ArrayList();//保存在数据库的文件地址，文件与文件用 ’-‘ 相连，格式endport/bucketName/foldname/文件名字。类型        
		int uploadCount=0;
		String typeUrl = "";
		for (int i = 0; i < sourceFiles.length; i++) {
			String fileName = sourceFiles[i].getOriginalFilename();
                         String suffixFileName =fileName.substring(fileName.lastIndexOf(".") + 1);  // 获得文件后缀名称
			  InputStream fileContent =  sourceFiles[i].getInputStream();			 
			 String url= OSSUploadUtil.uploadFile(fileContent,suffixFileName,orderid,type);
			 if(url!=null){
				 strlist.add(url);
				 uploadCount++;
			 }			 
			 System.out.println("-----------"+url);			 
		}
		//拼接多文件字符串地址
		List photos=null;//保存在数据库中的地址格式
		WLOrder wlo = wlOrderService.findWLOrderById(id);
		String JsonStr=null;
		
		if (0 == type) {// type="金域达交接单";
			JsonStr= wlo.getTransferorderphoto();
		} else if (1 == type) {// type="金域达运单";
			JsonStr=wlo.getWaybillnophoto();
		} else if (2 == type) {// type="温控报告";
			JsonStr=wlo.getTemperreportphoto();
		} 		
		if(StringUtils.isEmpty(JsonStr)){//数据库中查询是否有数据
			photos=new ArrayList();
		}else{
			//数据库中已经存在数据，在拼接
			JSONArray jsonArray=JSONArray.fromObject(JsonStr);
			List list2 = JSONArray.toList(jsonArray, new HashMap<>(), new JsonConfig());
			photos=list2;
		}
		
		for (int i = 0; i  photoAddress=new HashMap<>();
			photoAddress.put("id", String.valueOf((photos.size()+i+1)));
			photoAddress.put("name", strlist.get(i));
			//photoAddress.put(String.valueOf(i+1), strlist.get(i));
			photos.add(photoAddress);
		}
		JSONArray listArray=JSONArray.fromObject(photos);
		System.out.println("==================------------------------------"+typeUrl);
		if (0 == type) {
			// type="金域达交接单";
			wlOrder.setTransferorderphoto(listArray.toString());
		} else if (1 == type) {
			// type="金域达运单";
			wlOrder.setWaybillnophoto(listArray.toString());
		} else if (2 == type) {
			// type="温控报告";
			wlOrder.setTemperreportphoto(listArray.toString());
		} else {
			return renderError("上传失败");
		}
		wlOrderService.updateWLOrderByOrderID(wlOrder);
		String typeStr = null;
		return renderSuccess("上传成功文件数量为:"+uploadCount);
	}
//3、列表显示：
	/** 获取bucket中文件对象
	 * @author   
	 * @date 
	 * @param 
	 * @return
	 */
	@RequestMapping(value = "/getBucketKey", method = RequestMethod.POST)
	@ResponseBody
	public Object getBucketKey(String orderid,int type,Long id,String sort, String order) {
		List photos=null;//保存在数据库中的地址格式
		WLOrder wlo = wlOrderService.findWLOrderById(id);
		String JsonStr=null;
		if (0 == type) {// type="金域达交接单";
			JsonStr= wlo.getTransferorderphoto();
		} else if (1 == type) {// type="金域达运单";
			JsonStr=wlo.getWaybillnophoto();
		} else if (2 == type) {// type="温控报告";
			JsonStr=wlo.getTemperreportphoto();
		} 
		if(StringUtils.isEmpty(JsonStr)){//数据库中查询是否有数据
			photos=new ArrayList();
		}else{
			JSONArray jsonArray=JSONArray.fromObject(JsonStr);
			List list2 = JSONArray.toList(jsonArray, new HashMap<>(), new JsonConfig());
			photos=list2;
		}	
		List> res= photos;
		return res;
	}
//4、删除： 
        /*** 删除操作 * @param objectKey
	 * @param type
	 * @return
	 */
	@RequestMapping(value="/delPhoto",method=RequestMethod.GET)
	@ResponseBody
	public Object delPhoto(String objectKey,int type,Long id,String orderid){
		boolean res= OSSUploadUtil.deleteFile(objectKey, type);
		if(!res){
			return renderError("删除失败");
		}
		List photos=null;//保存在数据库中的地址格式
		WLOrder wlo = wlOrderService.findWLOrderById(id);
		String JsonStr=null;
		
		if (0 == type) {// type="金域达交接单";
			JsonStr= wlo.getTransferorderphoto();
		} else if (1 == type) {// type="金域达运单";
			JsonStr=wlo.getWaybillnophoto();
		} else if (2 == type) {// type="温控报告";
			JsonStr=wlo.getTemperreportphoto();
		} 
		JSONArray jsonArray=JSONArray.fromObject(JsonStr);
		//List list2 = JSONArray.toList(jsonArray, new HashMap<>(), new JsonConfig());
		int index=-1;
		for (int i = 0; i < jsonArray.size(); i++) {
			JSONObject jsonObject = (JSONObject) jsonArray.get(i);
			//JSONObject jsonObject2 = jsonObject.discard("name");
			String str= (String) jsonObject.get("name");	
			//jsonArray1.add(jsonObject2);
			if(objectKey.equals(str)){
				index=i;
			}
		}
		jsonArray.remove(index);
		WLOrder wlOrder = new WLOrder();
		wlOrder.setOrderid(orderid);
		if (0 == type) {
			// type="金域达交接单";
			wlOrder.setTransferorderphoto(jsonArray.toString());
