Java任务调度

最近项目要用到任务调度的相关知识，昨天信心满满的去官网学习，结果被坑个半死，我用的最新版的quartz，文档里说是兼容所有版本，但是代码连编译都报错，无奈只好从网上找资料，摸着石头过河总算有点眉目，在此分享，顺便记录。

Maven项目：

pom.xml引用如下： org.quartz-scheduler quartz 2.1.7 org.quartz-scheduler quartz-oracle 2.1.7 org.quartz-scheduler quartz-weblogic 2.1.7 org.quartz-scheduler quartz-jboss 2.1.7

相关类如下：

package test.quartz;

import java.util.Date;

import org.quartz.Job;

import org.quartz.JobExecutionContext;

import org.quartz.JobExecutionException;

public class SimpleJob implements Job

{

// ①实例Job接口方法 public void execute(JobExecutionContext context) throws JobExecutionException { // Say Hello to the World and display the date/time System.out.println("Hello World! - " + new Date());

}

}

package test.quartz;

import org.quartz.JobBuilder;

import org.quartz.JobDetail;

import org.quartz.Scheduler;

import org.quartz.SchedulerFactory;

import org.quartz.SimpleScheduleBuilder;

import org.quartz.Trigger;

import org.quartz.TriggerBuilder;

public class SimpleTriggerRunner{

public static void main(String[] args) throws Exception

{

SchedulerFactory schedFact = new org.quartz.impl.StdSchedulerFactory();

Scheduler sched = schedFact.getScheduler(); // define the job and tie it to our HelloJob class

JobDetail job = JobBuilder.newJob(SimpleJob.class).withIdentity("myJob", "group1").build(); // Trigger the job to run now, and then every 40 seconds

Trigger trigger = TriggerBuilder.newTrigger().withIdentity("myTrigger", "group1").startNow().withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(2).repeatForever()).build();

// Tell quartz to schedule the job using our trigger

sched.scheduleJob(job, trigger);

sched.start();

Thread.sleep(9L * 1000L);

sched.shutdown(true);

}

}

以上demo是最简单的入门例子，更多复杂的说明还是需要参考文档的说明。
