spring 定时任务

<!-- Enables the Spring Task @Scheduled programming model -->
    <task:executor id="executor" pool-size="5" />
    <task:scheduler id="scheduler" pool-size="10" />
    <task:annotation-driven executor="executor" scheduler="scheduler" />

以上三行代码用于声明spring定时任务的执行和轮询，之后在需要定时任务的实体上标注@Component:如：

 

@Component
public class Onlines {
    
    @Resource
    private OnlinesServiceImpl onlinesServiceImpl;
    
    @Scheduled(cron = "0 0/5 * * * *")
    public void record(){
        AuthUserData authUser = new AuthUserData();
        authUser.setId(GlobalInfo.SYSTEM_ID);
        OnlinesEntity info = new OnlinesEntity();
        info.setTotalCount(AuthUserSessionListener.onLines());
        onlinesServiceImpl.save(info, authUser);
    }

}
