需要实现 ApplicationListener<ContextRefreshedEvent>

@Componentpublic class CrawlerInitialize implements ApplicationListener
    
      {    @Override    public void onApplicationEvent(ContextRefreshedEvent event) {        CrawlerWebsiteService crawlerWebsiteService = SpringContextHolder.getBean(CrawlerWebsiteService.class);        crawlerWebsiteService.initCrawlerStatus(StatusEnum.STOP.getValue());    }}
    

@PostConstruct ：可以使用@PostConstruct注解一个方法来完成初始化,@PostConstruct注解的方法将会在依赖注入完成后被自动调用
