java quartz TriggerBuilder

TriggerBuilder主要用来创建触发器,触发器必须要绑定job才有效

1.trigger的jobdata和jobdtail对象的是独立,不是一个

package com;


import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;

import java.io.IOException;

import static org.quartz.JobBuilder.newJob;
import static org.quartz.TriggerBuilder.newTrigger;


public class clroja {
    
    
    public static class myJob implements Job {
    
    
        @Override
        public void execute(JobExecutionContext context){
    
    
            JobDataMap jobDataMap = context.getJobDetail().getJobDataMap();
            System.out.println(jobDataMap.getString("key1"));
            JobDataMap jobDataMap1 = context.getTrigger().getJobDataMap();
            System.out.println(jobDataMap1.getString("key2"));
        }
    }

    public static void main(String[] args) throws IOException, SchedulerException {
    
    
        Scheduler sched = new StdSchedulerFactory().getScheduler();

        JobDetail job = newJob(myJob.class)
                .withIdentity("job1", "group1") //设置job的名称和分组,以便后期的查找
                .usingJobData("key1","value1") // 使用JobData向job中传递参数
                .storeDurably() // 在使用scheduler.addJob 单独添加job(不指定trigger)时使用,因为框架的思想是只在执行时才创建对象,所以要指定durably
                .withDescription("new job") // 添加注释,一般不用
                .build(); //build设计模式生成对象

        Trigger trigger = newTrigger()
                .withIdentity("trigger1", "group1")
                .usingJobData("key2","value2") //和JobData不是同一个对象
                .forJob(JobKey.jobKey("job1","group1")) // 给单独添加的jobdetail添加触发器
                .startAt(DateBuilder.futureDate(1,DateBuilder.IntervalUnit.SECOND)) // 还有便捷的方法startNow(),一般用于测试 DateBuilder另有文章说明
                .endAt(DateBuilder.futureDate(5,DateBuilder.IntervalUnit.SECOND)) // 关闭出发器,停止任务
                .withSchedule(SimpleScheduleBuilder.simpleSchedule().repeatForever().withIntervalInSeconds(1))
                .withPriority(1)//设置优先级
                .withDescription("new trigger")
                .build();
        sched.scheduleJob(job, trigger);
        sched.start();
    }
