How To Check Existence Of Xml File In Resources Folder In Java?

- 1 answer

I wanan check is the resources folder has a xml with the given name. I can do by using File class and then check exists() method, but I was wondering if I can refer to resource file as a Resource and not by File? I tried following but it does not seem to work :

 Resource resource = new ClassPathResource("resources/folder/test.xml");//this file is existing

 if(resource.exists())
    {
      System.out.println(" SUCCESS ");

    }
    else
    {
      System.out.println(" FAIL . RESOURCE NOT FOUND");
    }

Its always going else block when this piece of code is executed.What did I miss?

The src/main/resources is the root of the classpath (or the files in there are added to the root. So resources/folder/test.xml would expect a file in src/main/resources/resources/folder/test.xml. This is probably not what you want. Remove the resources part in the file path.

Resource resource = new ClassPathResource("/folder/test.xml");
if(resource.exists()) {
  System.out.println(" SUCCESS ");
} else {
  System.out.println(" FAIL . RESOURCE NOT FOUND");
}

Should do the trick.
