详解springboot容器加载完后执行特定操作

public class ApplicationStartup implements ApplicationListener{
  public void onApplicationEvent(ContextRefreshedEvent event)
   {
    //在容器加载完毕后获取dao层来操作数据库
    OSSVideoRepository ossVideoRepository = (OSSVideoRepository)event.getApplicationContext().getBean(OSSVideoRepository.class);
    //在容器加载完毕后获取配置文件中的配置
    ServerConfig serverCOnfig= (ServerConfig)event.getApplicationContext().getBean(ServerConfig.class);
    
    ServerFileScanner fileScanner = new ServerFileScanner(
        ossVideoRepository, serverConfig.getScanpath());
    //在容器加载完毕后启动线程
    Thread thread = new Thread(fileScanner);
    thread.start();
   }
}

@Component
@ConfigurationProperties(prefix = "server")
public class ServerConfig {
  private String aliyunossEndpoint;
  private String aliyunossAccessKeyId;
  private String aliyunossAccessKeySecret;
  private String aliyunossBucketName;
  private String scanpath;
