1.首先配置 spring3 的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd">
<context:component-scan base-package="test.jdbc" />
<!-- 线程数目 -->
<task:executor id="executor" pool-size="10" />
<!-- 定时器数目 -->
<task:scheduler id="scheduler" pool-size="10" />
<task:annotation-driven executor="executor" scheduler="scheduler" />
</beans>
2.建立实体类
package test.jdbc;
import java.util.Calendar;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class Timer {
private static final Logger log = LoggerFactory.getLogger(Timer.class);
//固定频率每5秒钟执行一次
@Scheduled(fixedDelay=5000)
public void run(){
log.info("time{}",Calendar.getInstance().getTimeInMillis());
}
//在每小时的 32分钟到55分钟之间每2秒钟执行一次
@Scheduled(cron="*/2 32-55 * * * *")
public void runTimeHour(){
log.info("...........................hour to hor");
}
}
3.执行结果：
17:46:27.441 [scheduler-2] INFO test.jdbc.Timer - time1432806387437
17:46:28.001 [scheduler-2] INFO test.jdbc.Timer - ...........................hour to hor
