你是运行的这个案例吗？
/UI2/demo/takeoutAdmin/index.w

这个路径下文件存在吗？？默认没删除吧
/UI2/demo/takeoutAdmin/data/attachmentSimple/001/C6F709CE3F7000012AB490B41F107230

是自己重新上传的？还是默认的？

我自己在外卖案例基础上又导的一个案例，估计是我不小心删掉了某些文件，就是不懂model\UI2\demo\takeoutAdmin\data\attachmentSimple\t001\C7922A9A4EE0000110F9135812781CBC (系统找不到指定的路径。)，这个文件到底是干嘛用的。

这是功能通过attachmentSimple组件上传的文件！
访问这个图片的时候，就会调用java代码去找这个文件！如果文件不存在，就不会报错！

看下对应案例的java代码
