As for the method for obtaining relative paths in Web applications, I will not mention it because of its limitations. Here I am talking about all the methods that can be used in any environment.
What is the safest way to get relative paths? The answer is to take the location of the file stored by the class itself in the system, and then find the classpath Based on the package hierarchy. The implementation is very simple. Well, let's not talk about th
