1、写好JAVA类TimerTaskTest 必须继承TimerTask
package spring;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Date;
import java.util.TimerTask;
import org.springframework.beans.BeansException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TimerTaskTest extends TimerTask {
public static void main(String[] args) throws IOException {
try {
try {
new ClassPathXmlApplicationContext(new String[] {"beans-config.xml"});
} catch (BeansException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("启动 Task..");
System.out.println("请输入 exit 关闭 Task: ");
BufferedReader reader =new BufferedReader(new InputStreamReader(System.in));
while(true) {
if(reader.readLine().equals("exit")) { System.exit(0);}
}
}
@Override
public void run() {
System.out.println(new Date().toLocaleString()+">>>>>>>>>>正在执行定时任务");
}
}
2、配置Spring 的 xml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"
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 ">
<bean id="demoTask" class="spring.TimerTaskTest"/>
<bean id="scheduledTimerTask" class="org.springframework.scheduling.timer.ScheduledTimerTask">
<property name="timerTask">
<ref bean="demoTask"/>
</property>
<property name="period">
<value>60000</value>
</property>
<property name="delay">
<value>10000</value>
</property>
</bean>
<bean id="timerFactoryBean" class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<ref bean="scheduledTimerTask"/>
</list>
</property>
</bean>
</beans>
3、在上面写的JAVA类中的main方法里面，运行即可执行定时任务
