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(); ;
}
}
如下图:
第二步:在web.xml文件中配置监听
<listener>
<listener-class>com.wbg.treasure.controller.ScheduleController</listener-class>
</listener>
