异常处理：

在文件上传时候，会在C:\Users\用户给\AppData\Local\Temp\下生成个如下的临时文件：
undertow111112121upload

当MultipartFile执行保存的时候（MultipartFile.transferTo(file)），会把临时文件 删除 ，再执行MultipartFile.getSize()的时候，就会出现找不到临时文件的异常。

so…需要获取文件大小 的时候，需要在执行保存文件之前 进行获取文件大小。
至此，问题解决。

ps:这个问题是我在用spring boot 多项目+ spring cloud的时候出现的，单springboot项目的时候，没有遇到这个问题。
