Spring+quartz实现任务调度的小例子

---

实现任务调度分为三大模块：1.任务调度器Scheduler;
2.触发器cronTrigger；
3.自定义任务JobtTask；

---

*自定义任务JobtTask*

package com.zjt.quartz;



import java.text.SimpleDateFormat;
import java.util.Date;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

/**
 * 自定义任务;
 */
public class MyJob implements Job {
	// 自定义任务Task;
	public void execute(JobExecutionContext context) throws JobExecutionException {
		System.out.println("当前任务开始执行: " +
	     new SimpleDateFormat("yyyy-MM-dd HH-mm-ss")
	     .format(new Date()));
	}
}

*测试类*

package com.zjt.quartz;

import java.text.ParseException;

import org.quartz.JobExecutionException;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**
 *  测试类
 */
public class Test {
	@SuppressWarnings("resource")
	public static void main(String[] args) throws ParseException, JobExecutionException {
		System.out.println("--------------------------------");
		new ClassPathXmlApplicationContext("applicationContext.xml");
	}
}

	<bean name="myJobtTask" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
		<property name="jobClass" value="com.zjt.quartz.MyJob" />
	</bean>
</beans>

*quartz.properties*

# Configure Main Scheduler Properties

org.quartz.scheduler.instanceName = DefaultQuartzScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.rmi.export = false

#============================================================================
