注意:定時任務的組件(類)必定不要lazy init,能夠在配置文件中加default-lazy-init="false",或者在執行的組件上家註解@Lazy(false)
web
1.配置文件spring
先添加命名空間 spa
<?xml version="1.0" encoding="UTF-8"?> .net
<beans xmlns:task="http://www.springframework.org/schema/task" orm
xsi:schemaLocation="http://www.springframework.org/schema/task xml
http://www.springframework.org/schema/task/spring-task-4.0.xsd"> ci
<!-- here is a right place for such configuration get
--> it
<task:annotation-driven executor="myExecutor" scheduler="myScheduler"/> io
<task:executor id="myExecutor" pool-size="5"/>
<task:scheduler id="myScheduler" pool-size="10"/>
2.要執行的組件(類)
@Lazy (false)
public class PrintSchedule {
private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
// @Scheduled(cron = "0-59 * * * * *")//每秒執行一次
@Scheduled(cron = "0 */10 * * * *")//每十分鐘執行一次
public void reportCurrentTime() {
System.out.println("The time is now " + dateFormat.format(new Date()));
}
}
