How to load all files of a folder to a list of Resources in Spring?

I have a folder and want to load all txt files to a list using Spring and wildcards:

By annotation I could do the following:

@Value("classpath*:../../dir/*.txt")
private Resource[] files;

But how can I achieve the same using spring programmatically?

Use ResourceLoader and ResourcePatternUtils:

class Foobar {
    private final ResourceLoader resourceLoader;

    public Foobar(ResourceLoader resourceLoader) {
        this.resourceLoader = resourceLoader;
    }

    Resource[] loadResources(String pattern) throws IOException {
        return ResourcePatternUtils.getResourcePatternResolver(resourceLoader).getResources(pattern);
    }
}

and use it like:

Resource[] resources = foobar.loadResources("classpath*:../../dir/*.txt");

If you are using Spring

@Autowired
private ApplicationContext applicationContext;

public void loadResources() {
    try {
        Resource[] resources = applicationContext.getResources("file:C:/XYZ/*_vru_*");
    } catch (IOException ex) {
        ex.printStackTrace();
    }
}
