@Autowired静态注入导致的sonar坏味道：Write to static field ...Utils.staticService from instance method ...Utils.init()

@Component
public class RuleDocTypeUtils {

     private static final Logger LOGGER =  LoggerFactory.getLogger(RuleDocTypeUtils.class);
     
     private static DocTypeRuleServiceImpl staticService = new  DocTypeRuleServiceImpl();
    
     @Autowired
     private DocTypeRuleServiceImpl dynamicService;
     
     @PostConstruct
     public void init() {
           setService(dynamicService);
     }

     private void setService(DocTypeRuleServiceImpl  dynamicService) {
           setStaticService(dynamicService);
     }

     private synchronized static void  setStaticService(DocTypeRuleServiceImpl dynamicService) {
           RuleDocTypeUtils.staticService = dynamicService;
     }

     ...

}
