使用spring的@Scheduled注解执行定时任务，启动项目不输出警告

Posted 2020-08-14

在applicationContext.xml中添加：

xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-4.0.xsd">


<task:annotation-driven executor="myExecutor" scheduler="myScheduler" />
<task:executor id="myExecutor" pool-size="5" />
<task:scheduler id="myScheduler" pool-size="10" />

 

java代码：

@Component
public class CleanExpireTokenTask {

    private Logger logger = LoggerFactory.getLogger(LogTag.BUSINESS);
    
    @Scheduled(cron = "0 * * * * ?")
    public void startUpdateSaleThread(){
        try{
            System.out.println("check token expire");
        }catch(Exception e){
            logger.error("Make salesReport faild",e);
        }
    }
}

 

注意：

实现类上要加注解@Component

定时器的任务方法不能有返回值
