spring添加定时器

1.spring的配置文件中添加

xmlns:task="http://www.springframework.org/schema/task"

然后xsi:schemaLocation加下面的内容、

http://www.springframework.org/schema/task 
http://www.springframework.org/schema/task/spring-task.xsd

 

<!-- task任务扫描注解 --> 
 <task:annotation-driven/>
 <context:component-scan base-package="arch.pub.timer"></context:component-scan>

 

2。在arch.pub.timer包下新建class bean

@Service
public class LeaveTimer {
 private static final Logger logger = LogManager.getLogger(LeaveTimer.class.getName());
 
 @Scheduled(cron="0/5 * * * * ? ") //每5秒执行一次
 public void run() throws Exception {
  logger.error(UtilTime.getCurrentTime());
 }
}

即可
