How to use Spring ClassPathResource: with classpath: or classpath*: and leading / or not?

Question

I having file in the location

--src
  --> main
   --> config
    --> application
     --> context
      --> reference
       --> user
        --> user.xml

where

    --src
      --> main
       --> config

is in the classpath. Now I am trying to access the file using

Resource resource = new ClassPathResource("classpath**:/application/context/references/user/user.xml");
File file = resource.getFile();

But I getting FileNotFoundException, I tried with

Resource resource = new ClassPathResource("classpath:/application/context/references/user/user.xml");
File file = resource.getFile();

too, but still I getting the exception. Can someone help me to understand the working of ClassPathResource and right solution?

Try to determine the starting path in ClassPath, `Resource resource = new ClassPathResource("" or File.seperator); resource.getFile().getAbsolutePath();` So that you can give the appropriate value inside new CPR() based on above result — The Coder, Apr 13 '16 at 05:02
remove "classpath:", see [this answer](http://stackoverflow.com/a/8725288/180100) and http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/io/ClassPathResource.html#ClassPathResource-java.lang.String- — , Apr 13 '16 at 05:23
@RC., you are right, Yesterday I tried the same, but I think I didn't test it correctly. — Suganthan Madhavan Pillai, Apr 13 '16 at 05:53

Use as below

Resource resource = new ClassPathResource("/application/context/references/user/user.xml");
File file = resource.getFile();

The leading slash is unnecessary according to the [class documentation](https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/io/ClassPathResource.html): _A leading slash will be removed, as the ClassLoader resource access methods will not accept it._ – David Riccitelli Jul 09 '19 at 08:18
`java.io.FileNotFoundException: class path resource [logging_date.txt] cannot be resolved to URL because it does not exist` It cannot find the file. – likejudo Mar 24 '23 at 22:01
