Spring+Quartz搞定web定时任务

导入依赖的包，我用的是maven，pom.xm配置文件如下

添加自己的类，执行定时任务

package com.qiny.quartz;

import java.util.Date;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
//需要继承QuartzJobBean
public class MyTask extends QuartzJobBean {

	@Override
	protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException {
		System.out.println("启动了"+new Date());
	}

}

添加spring配置 文件：

	</bean>

	<!-- 添加触发器 -->
