如何在Maven项目中获取资源文件的相对路径？

Question

My project uses Maven and is a little bit complicated. I can't seem to get a relative path for a resource file. The structure is like this:

project_folder
    |-package1
       |-src
          |-test
              |-java
                |-folder1
                  |-folder2
                     ...
                       |-foldern
                           |-**myfile**

              |-resources
                |-folder
                  |-**targetfile**

In test , there is a java folder and a resources folder . myfile is deep within the java folder. So in myfile , I want to refer to the relative path of target file . What is the path?

Answer 1

Assuming you have not changed the defaults for test source and resource location:

MyFile.class.getResourceAsStream("../../../folder/targetfile");

with N "../" instead of 3. It would of course be easier to do:

MyFile.class.getResourceAsStream("/folder/targetfile");
