1、spring的配置文件
[html]
view plain copy<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:task="http://www.springframework.org/schema/task"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-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/jee http://www.springframework.org/schema/jee/spring-jee-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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd">
<task:annotation-driven /> <!-- 定時(shí)器開關(guān)-->
<bean id="myTaskXml" class="com.spring.task.MyTaskXml"></bean>
<task:scheduled-tasks>
<!--
這里表示的是每隔五秒執(zhí)行一次
-->
<task:scheduled ref="myTaskXml" method="show" cron="*/5 * * * * ?" />
<task:scheduled ref="myTaskXml" method="print" cron="*/10 * * * * ?"/>
</task:scheduled-tasks>
<!-- 自動(dòng)掃描的包名 -->
<context:component-scan base-package="com.spring.task" />
</beans>
2、基于xml的定時(shí)器任務(wù)[java]
view plain copypackage com.spring.task;
/**
* 基于xml的定時(shí)器
* @author hj
*/
public class MyTaskXml {
public void show(){
System.out.println("XMl:is show run");
}
public void print(){
System.out.println("XMl:print run");
}
}
3、基于注解的定時(shí)器任務(wù)[java]
view plain copypackage com.spring.task;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
/**
* 基于注解的定時(shí)器
* @author hj
*/
@Component
public class MyTaskAnnotation {
/**
* 定時(shí)計(jì)算。每天凌晨 01:00 執(zhí)行一次
*/
@Scheduled(cron = "0 0 1 * * *")
public void show(){
System.out.println("Annotation：is show run");
}
/**
* 心跳更新。啟動(dòng)時(shí)執(zhí)行一次，之后每隔2秒執(zhí)行一次
*/
@Scheduled(fixedRate = 1000*2)
public void print(){
System.out.println("Annotation：print run");
}
}
4、測(cè)試[java]
view plain copypackage com.spring.test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-mvc.xml");
}
}
運(yùn)行結(jié)果：
Annotation：print run
Annotation：print run
Annotation：print run
XMl:print run
XMl:is show run
Annotation：print run
Annotation：print run
