Answer 1

In Spring-boot Java framework, you can use the Value annotation conveniently within the class,

@Component
public class MyRunner implements CommandLineRunner {

@Value("classpath:thermopylae.txt") //Annotation
private Resource res; // res will hold that value the `txt` player

@Autowired
private CountWords countWords;

@Override
public void run(String... args) throws Exception {

    Map words =  countWords.getWordsCount(res);

    for (String key : words.keySet()) {

        System.out.println(key + ": " + words.get(key));
       }
   }
}
