1.配置文件添加
xmlns:task="http://www.springframework.org/schema/task"
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.2.xsd
2.配置任务扫描
<task:annotation-driven />
3.配置扫描任务位置
<context:component-scan base-package="com.vrveis.roundTrip.task" />
4.任务实现类
@Component
public class FlightTrainTask {
@Scheduled(cron = "0 0 */2 * * ? ") // 间隔2小时执行
public void taskCycle() {
System.out.println("定时任务");
}
}
- 必须声明@Component
0 0 */2 * * ?
为秒、分、时….
