Current directory in java properties file

Question

Is there any way of specifying the current directory in a java properties file?

ie something like:

fileLocation={currentDir}/fileName.txt

Answer 1

No. Properties files do not have any builtin macro facilities. You can programmatically get the currect directory of the user running the Java app through the user.dir system property .

Answer 2

我很确定它只是默认为当前目录，如果没有，你可以做到

fileLocation="./fileName.txt"

Answer 3

I don't know any direct solution for this problem. You can load the URL to the properties file and then load the filename from that file:

ClassLoader loader = YourClass.class.getClassLoader(); 
URL resourceURL =loader.getResource("check.properties");
String fileToLoad = resourceURL.getPath() + <fileNameFromPropertyFile>;
