1.main方法：
public static void main(String[] args) throws SchedulerException {
// TODO Auto-generated method stub
// 创建一个JobDetail实例 将HelloJob类添加到JobDetail中
JobDetail jobDetail = JobBuilder.newJob(helloJob.class)
.withIdentity("myJob", "jobDetailGroup")
.usingJobData("message1","date1")
.usingJobData("float1", 3.14f)
.build();
System.out.println(jobDetail.getKey().getName());
System.out.println(jobDetail.getKey().getGroup());
System.out.println(jobDetail.getJobClass().getName());
//创建一个Trigger实例，定义该job立即执行，每隔两秒钟重复执行一次，一直不停
Trigger trigger = TriggerBuilder.newTrigger()
.withIdentity("myTrigger","triggerGroup")
.usingJobData("triggerParam1","trigerParam1Value")
.startNow().withSchedule(
SimpleScheduleBuilder.simpleSchedule()
.withIntervalInSeconds(2)
.repeatForever())
.build();
//创建Schduler实例
SchedulerFactory sfFactory = new StdSchedulerFactory();
Scheduler scheduler = sfFactory.getScheduler();
scheduler.start();
//打印当前时间
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println("current scheduler time is :"+sdf.format(date));
scheduler.scheduleJob(jobDetail, trigger);
}
2.job实现类：
//实现job接口execute方法具体内容
public void execute(JobExecutionContext arg0) throws JobExecutionException{
//打印当前执行时间 格式：2017-01-01 00:00:00
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println("job execute time is :"+sdf.format(date));
//编写具体业务逻辑
System.out.println("helloJob类 实现了 Job接口的execute方法");
JobKey jobkey=arg0.getJobDetail().getKey();
System.out.println("Job name:"+jobkey.getName()+" and Job group:"+jobkey.getGroup());
TriggerKey trkey = arg0.getTrigger().getKey();
System.out.println("Trigger name:"+trkey.getName()+" and Trigger group:"+trkey.getGroup());
JobDataMap jobDM = arg0.getJobDetail().getJobDataMap();
JobDataMap triDM = arg0.getTrigger().getJobDataMap();
String jobMsg = jobDM.getString("message1");
Float jobFloatValue =jobDM.getFloat("float1");
String triMsg = triDM.getString("triggerParam1");
System.out.println("jobMsg:"+jobMsg);
System.out.println("jobFloatValue:"+jobFloatValue);
System.out.println("triMsg:"+triMsg);
}
3.运行结果：
current scheduler time is :2018-01-03 17:43:59
job execute time is :2018-01-03 17:43:59
helloJob类 实现了 Job接口的execute方法
Job name:myJob and Job group:jobDetailGroup
Trigger name:myTrigger and Trigger group:triggerGroup
jobMsg:date1
jobFloatValue:3.14
triMsg:trigerParam1Value
job execute time is :2018-01-03 17:44:01
helloJob类 实现了 Job接口的execute方法
Job name:myJob and Job group:jobDetailGroup
Trigger name:myTrigger and Trigger group:triggerGroup
jobMsg:date1
jobFloatValue:3.14
triMsg:trigerParam1Value
