WebApplicationContext applicationContext =  ContextLoaderListener.getCurrentWebApplicationContext();

@Component
@Lazy(false)
public class ApplicationContextRegister implements ApplicationContextAware {
    private static final Logger LOGGER = LoggerFactory.getLogger(ApplicationContextRegister.class);
    private static ApplicationContext APPLICATION_CONTEXT;

    /**
     * 设置spring上下文  *  * @param applicationContext spring上下文  * @throws BeansException
     */
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        LOGGER.debug("ApplicationContext registed-->{}", applicationContext);
        APPLICATION_CONTEXT = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        return APPLICATION_CONTEXT;
    }
}

CrawlerService crawlerService = ApplicationContextRegister.getApplicationContext().getBean(CrawlerService.class);
