tomcat启动完成执行某个方法定时任务(Spring)操作-创新互联

第一步引入接口： ServletContextListener

@RestController
@RequestMapping("/schedule")
public class ScheduleController implements ServletContextListener {
  @Autowired
  private ScheduleService scheduleService;

  @Override
  public void contextDestroyed(ServletContextEvent event) {
    System.out.println("销毁");
  }

  @Override
  public void contextInitialized(ServletContextEvent event) {
    WebApplicationContextUtils.getRequiredWebApplicationContext(event.getServletContext())
        .getAutowireCapableBeanFactory().autowireBean(this);
    System.out.println("开始执行周期任务");
    scheduleService.start(); ;
  }
}
