java中使用quartz实现定时，不使用spring框架

java中使用quartz实现定时，不使用spring框架

解决方法：

1.使用方法

//默认每30秒执行ConfigurationJob

QuartzManager.addJob("ConfigurationJob", "ConfigurationTrigger", ConfigurationJob.class, "0/30 * * * * ?");

2.核心类

import org.quartz.CronScheduleBuilder;

import org.quartz.CronTrigger;

import org.quartz.JobBuilder;

import org.quartz.JobDetail;

import org.quartz.JobKey;

import org.quartz.Scheduler;

import org.quartz.SchedulerFactory;

import org.quartz.Trigger;

import org.quartz.TriggerBuilder;

import org.quartz.TriggerKey;

import org.quartz.impl.StdSchedulerFactory;

public class QuartzManager {

private static SchedulerFactory schedulerFactory = new StdSchedulerFactory();

private static String JOB_GROUP_NAME = "DEFAULT_JOBGROUP_NAME";  //自定义

private static String TRIGGER_GROUP_NAME = "DEFAULT_TRIGGERGROUP_NAME";  //自定义

public static void addJob(String jobName, String triggerName, Class jobClass, String cron) {  

       try {  

           Scheduler sched = schedulerFactory.getScheduler();  

           // 任务名，任务组，任务执行类

           JobDetail jobDetail= JobBuilder.newJob(jobClass).withIdentity(jobName, JOB_GROUP_NAME).build();

           // 触发器  

           TriggerBuilder<Trigger> triggerBuilder = TriggerBuilder.newTrigger();

           // 触发器名,触发器组  

           triggerBuilder.withIdentity(triggerName, TRIGGER_GROUP_NAME);

           triggerBuilder.startNow();

           // 触发器时间设定  

           triggerBuilder.withSchedule(CronScheduleBuilder.cronSchedule(cron));

           // 创建Trigger对象

           CronTrigger trigger = (CronTrigger) triggerBuilder.build();

           // 调度容器设置JobDetail和Trigger

           sched.scheduleJob(jobDetail, trigger);  

           // 启动  

           if (!sched.isShutdown()) {  

               sched.start();  

           }  

       } catch (Exception e) {  

           throw new RuntimeException(e);  

       }  

   }

}

3.任务类

import org.quartz.Job;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

public class ConfigurationJob implements Job{

@Override

public void execute(JobExecutionContext arg0) throws JobExecutionException {

//定时代码

}

}

4.下载quartz-2.3.0.jar
