并且只获取MD5,不保存文件。

I think you need to know the content to calculate the md5, just like the download website will give the md5 of the downloaded file, and then you can use a tool to calculate the md5 of the file after downloading and compare it with the md5 given by the website to see if the file has not been tampered with, java Also get the file calculation

It is best if the system where you download the address can tell you the MD5 value, otherwise you have to download it and calculate it yourself.
