如何在不指定驱动器的情况下在“ src”（源）目录中创建文件

Question

I know how to create file in Java with a specific path.
I want to create file in the source folder of the project without specifing the drive because it can change from PC to PC.

I tried to use:

File targetFile = new File("/src/SavedGames/uploadedFile.xml");
targetFile.createNewFile();

with dot before the 'src':

File targetFile = new File("./src/SavedGames/uploadedFile.xml");
targetFile.createNewFile();

with \\\\ :

File targetFile = new File("\\src\\SavedGames\\uploadedFile.xml");
targetFile.createNewFile();

It doesn't work, it throws exception.

This one works but creates it on my Apache server folder:

File targetFile = new File("uploadedFile.xml");
targetFile.createNewFile();

This is the hierarchy:

The code runs on the LoadGameServlet.java

Answer 1

您甚至可以在创建实际文件之前，使用诸如System.out.println(targetFile.getAbsolutePath())的工具调试将在何处创建文件。

Answer 2

After searching alot I found a way to do it.

File targetFile = new File(new File(LoadGameServlet.class.getProtectionDomain().getCodeSource().getLocation().getPath()).getParent() + "\\uploadedFile.xml");
String decoderPath = java.net.URLDecoder.decode(targetFile.getPath(), "UTF-8");
String newPath = decoderPath .replaceAll("build\\\\web\\\\WEB-INF\\\\classes\\\\Servlets", "src\\\\java\\\\SavedGames");
targetFile = new File(newPath);
targetFile.createNewFile();

I checked it and it works fine.

Thanks for your help.
