quartz 学习

Spring配置使用quartz

public interface SchedulerTask {
public void testMethod();
}
public class SchedulerTaskImpl implements SchedulerTask {
    public void testMethod(){
    	System.out.println("helloworld"+new Date().toLocaleString());
    }

}

<bean id="testService" class="com.downjoy.app.smtpfbackend.common.service.SchedulerTaskImpl">
</bean>
   <!-- 注册具体的定时任务到applicationContext -->
    <bean id="testJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <!-- 任务具体对象 -->
        <property name="targetObject" ref="testService"/>
        <!-- 具体的方法 -->
        <property name="targetMethod" value="testMethod"/>
    </bean>


    <!-- 配置触发器 ,为定时任务设置执行时间等属性 -->
    <bean id="testJobCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
        <property name="jobDetail" ref="testJob"/>
        <!-- 每分钟触发一次 -->
        <property name="cronExpression" value="0 */1 * * * ?"/>
    </bean>




    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <!-- 添加触发器 -->
        <property name="triggers">
            <list>
                  <ref local="testJobCronTrigger"/>
            </list>
        </property>


    </bean>

纯java代码使用quartz

/**
 * 
 */
package test;

import java.util.Date;

import org.quartz.CronExpression;
import org.quartz.CronTrigger;
import org.quartz.Job;
import org.quartz.JobDetail;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;

 class SchedulerManager{
	  public void start() throws SchedulerException
	  {
	    SchedulerFactory schedulerFactory = new StdSchedulerFactory();
	    Scheduler scheduler = schedulerFactory.getScheduler();

	    JobDetail jobDetail = new JobDetail("jobDetail", "jobDetailGroup", MyTimeTask.class);
	    CronTrigger cronTrigger = new CronTrigger("cronTrigger", "triggerGroup");
	    try {
	      CronExpression cexp = new CronExpression("1 * * * * ?");
	      cronTrigger.setCronExpression(cexp);
	    } catch (Exception e) {
	      e.printStackTrace();
	    }		
	    scheduler.scheduleJob(jobDetail, cronTrigger);
	    scheduler.start();
	  }   
}


public class Test {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		try {
			new SchedulerManager().start();
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

}

MyTimeTask必须写在另一个java文件中,否则反射出错。

import java.util.Date;

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

public  class MyTimeTask implements Job{
    public void execute(JobExecutionContext context) throws JobExecutionException{
        System.out.println("helloWorld"+new Date().toLocaleString());
 }
}
