Quartz入门03

接下来，我们用Cron表达式加配置文件的方式，写一个简单的例子

1、首先是任务类
1.1、Job001

package com.neohope.quartz.test;

import org.quartz.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.Date;

/**
 * Created by Hansen
 */
public class Job001 implements Job {
    private static Logger logger = LoggerFactory.getLogger(Job001.class);

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        logger.info("Job001 Executing : " + new Date());

        //获取Job的参数
        JobDetail jobDetail = jobExecutionContext.getJobDetail();
        //String jobDesc = jobDetail.getDescription();

        JobDataMap dataMap = jobDetail.getJobDataMap();
        String message = dataMap.getString("JOB_MSG");
        logger.info("Job001 Message is : " + message);

    }
}

1.2、Job002

package com.neohope.quartz.test;

import org.quartz.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.Date;

/**
 * Created by Hansen
 */
public class Job002 implements Job {
    private static Logger logger = LoggerFactory.getLogger(Job002.class);

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        logger.info("Job002 Executing : " + new Date());

        //获取Job的参数
        JobDetail jobDetail = jobExecutionContext.getJobDetail();
        //String jobDesc = jobDetail.getDescription();

        JobDataMap dataMap = jobDetail.getJobDataMap();
        String message = dataMap.getString("JOB_MSG");
        logger.info("Job002 Message is : " + message);
    }
}

2、然后是测试类

package com.neohope.quartz.test;

import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.Date;


/**
 * Created by Hansen
 */
public class Test002 {

    public void run() throws Exception {
        Logger logger = LoggerFactory.getLogger(Test002.class);

        SchedulerFactory sf = new StdSchedulerFactory();
        Scheduler scheduler = sf.getScheduler();

        scheduler.start();
        logger.info("scheduler started");

        try {
            System.in.read();
        } catch (Exception e) {
        }

        scheduler.shutdown(true);
        logger.info("scheduler ended");
    }

    public static void main(String[] args) throws Exception {
        System.setProperty("org.quartz.properties","quartzN.properties");

        Test002 test = new Test002();
        test.run();
    }
}

3、Quartz配置文件

4、任务配置文件
