Reading sub-directories of a directory in class path resources with Spring Boot

I was trying to read sub-directories(names of directories) of a directory in my class path resources using Spring Boot with snippet given below.

    public List<File> getSubdirectories() {
    File file = ResourceUtils.getFile("classpath:/database/scripts");
    return Arrays.stream(file.listFiles()).filter(File::isDirectory).map(File::getFileName)
            .collect(Collectors.toList());
    }

Now this would work well when we run this code from IDE. But when we build this app as a jar and runs it from there it throws a FileNotFoundException.

I tried to load the directory as class path resource as well. But didn't find any luck.

I'm currently using Java 8. So most of the Java 7 solutions won't work I guess. Is there any other way I can resolve this issue?

As per Spring documentation ResourceUtils are to be used internally within the framework

Try using Resource instead:

@Value("classpath:database/scripts")
Resource directories;

Alternatively, you can use resource loader:

@Autowired
ResourceLoader resourceLoader;
...
public Resource loadDirectories() {
    return resourceLoader.getResource(
      "classpath:database/scripts");
}
