业务描述：多图片上传

准备工作：图片上传接口、图片预览接口、图片存储接口

url: {

          fileUpload: window._CONFIG['domianURL']+"/sys/common/upload",//图片上传接口，jeecg自带

          imgerver: window._CONFIG['domianURL']+"/sys/common/view",//图片预览接口，jeecg自带

          add: "/Bshopbusniess/fileUpload/add",//存图接口，自己代码生成

        },

 

效果：
