1、定时调度模块

package controller;

import java.io.IOException;
import java.io.InputStream;
import java.util.Date;
import java.util.Enumeration;
import java.util.Properties;
import static org.quartz.CronScheduleBuilder.cronSchedule;
import static org.quartz.JobBuilder.newJob;
import static org.quartz.TriggerBuilder.newTrigger;
import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.impl.StdSchedulerFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.jfinal.plugin.IPlugin;

/**
 *  实现作业的调度
 * @author jerri liu

 */
public class QuartzPlugin implements IPlugin {
 private Logger logger = LoggerFactory.getLogger(getClass());
 private SchedulerFactory sf = null;
 private Scheduler sched = null;
 private String config = "job.properties";
 private Properties properties;

 public QuartzPlugin(String config) {
  this.config = config;
 }

 public QuartzPlugin() {
 }

 @SuppressWarnings({ "rawtypes", "unchecked" })
 public boolean start() {
        sf = new StdSchedulerFactory();
        try {
            sched = sf.getScheduler();
        } catch (SchedulerException e) {
            new RuntimeException(e);
        }
        loadProperties();
        Enumeration enums = properties.keys();
        while (enums.hasMoreElements()) {
            String key = enums.nextElement() + "";
            if (!key.endsWith("job")) {
                continue;
            }
            String cronKey = key.substring(0, key.indexOf("job")) + "cron";
            String enable = key.substring(0, key.indexOf("job")) + "enable";
            if (isDisableJob(enable)) {
                continue;
            }
            String jobClassName = properties.get(key) + "";
            String jobCronExp = properties.getProperty(cronKey) + "";
            Class clazz;
            try {
                clazz = Class.forName(jobClassName);
            } catch (ClassNotFoundException e) {
                throw new RuntimeException(e);
            }
            JobDetail job = newJob(clazz).withIdentity(jobClassName,
                    jobClassName).build();
            CronTrigger trigger = newTrigger()
                    .withIdentity(jobClassName, jobClassName)
                    .withSchedule(cronSchedule(jobCronExp)).build();
            Date ft = null;
            try {
                ft = sched.scheduleJob(job, trigger);
                sched.start();
            } catch (SchedulerException ee) {
                new RuntimeException(ee);
            }
            logger.info(job.getKey() + " has been scheduled to run at: " + ft
                    + " and repeat based on expression: "
                    + trigger.getCronExpression());
        }
        return true ;
    }

 private boolean isDisableJob(String enable) {
  return Boolean.valueOf(properties.get(enable) + "") == false;
 }

 private void loadProperties() {
  properties = new Properties();
  InputStream is = QuartzPlugin.class.getClassLoader()
    .getResourceAsStream(config);
  try {
   properties.load(is);
  } catch (IOException e) {
   throw new RuntimeException(e);
  }
 }

 public boolean stop() {
  try {
   sched.shutdown();
  } catch (SchedulerException e) {
   logger.error("shutdown error", e);
   return false;
  }
  return true;
 }
 
 public static void main(String []args)  {
  QuartzPlugin plugin = new QuartzPlugin();
  plugin.start();
  System.out.println("执行成功!!!");
  
 }
}

2、定时任务模块

package controller;

import java.util.Date;

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

public class HelloJob implements Job
{

 public void execute(JobExecutionContext context)
 throws JobExecutionException {
  Date date = new Date();
  System.out.println(date.getTime());
  System.out.println("你好");
 }
}

3、配置文件

smsup.job=controller.HelloJob
smsup.cron= 0/5 * * * * ?
smsup.enable=true
