There is no problem with the Linux file path when deploying the window and Linux projects

I haven't written a blog for a long time. Last week, I tested the project and found some bugs. One of them is a bit confusing. The description is as follows:

The project is deployed on Windows, and the image upload function is normal. When deployed on a Linux server, an inexplicable error occurs (probably because I am mentally retarded and actually forgot* Differences between Linux and Windows file directories*)

Normally it should be like this:

In fact, it is like this:

Tudou, who had never encountered such a problem, was also a little confused. No matter what, I restarted the project first, but it didn't work . Then I checked Tomcat, but it still didn't work . I was in a difficult situation. As a senior rookie programmer, I naturally have the third, fourth, and fifth solutions (baidu, google, etc.). With the spirit of not giving up, I keep on going. OK, brother, I found it. Hahahaha. As for my mood at this moment, it is like I met you in the vast crowd.
After careful analysis of the problem, it turns out that the file storage path under Windows is:

path += "\\" + dirName + "\\" + ymd + "\\";

The result on Linux will be:

This is obviously different from the path we expected. Yes, I believe that students with a little computer knowledge can see what the problem is. That's right, just change \ to / and it will be ok. It's really smart and refreshing, but a moment of stupidity ruined half a day.
Compare this to:

//Note that there are differences between Linux and Windows. Linux uses \ and Windows uses //
	/*path += "\\" + dirName + "\\" + ymd + "\\";
	pathsrc += "\\" + dirName + "\\" + ymd + "\\";*/
	path += "/" + dirName + "/" + ymd + "/";
	pathsrc += "/" + dirName + "/" + ymd + "/";
