What is the right way to use an injected bean in a static method?

 

@Component
public class JustAClass{
  private static Service service;
 
  @Autowired
  private Service tmpService;
 
  @PostConstruct
  public void init() {
    service = tmpService;
  }
  
  public static void say() {
        service.sayHi();
  }
 
}
