java quartz Scheduler 操作Trigger

一个JobDetail可以有多个Trigger

//增

sched.scheduleJob(trigger);//trigger必须使用forJob绑定JobDetail

//查

System.out.println(sched.getTrigger(TriggerKey.triggerKey("trigger1","group1")));//通过TriggerKey获得
System.out.println(sched.getTriggersOfJob(JobKey.jobKey("job1","group1")));//通过JobKey获得,因为二者是绑定的

System.out.println(sched.getTriggerGroupNames());//获得所有组名
System.out.println(sched.getTriggerKeys(GroupMatcher.groupEquals("group1")));//获得组下所有的TriggerKey

//改

sched.rescheduleJob(TriggerKey.triggerKey("trigger1","group1"),newTrigger().build()); //更改job的Trigger

//删

sched.unscheduleJob(TriggerKey.triggerKey("trigger1","group1"));

整体代码

package com;


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

import java.io.IOException;

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


public class App {
    
    
    public static class myJob implements Job {
    
    
        @Override
        public void execute(JobExecutionContext context){
    
    
            System.out.println("hello");
        }
    }

    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
                .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
                .build(); //build设计模式生成对象

        Trigger trigger = newTrigger()
                .withIdentity("trigger1", "group1")
                .forJob(JobKey.jobKey("job1","group1")) // 给单独添加的jobdetail添加触发器
                .build();
        sched.addJob(job,false);// false表示不替换,ture表示替换,既更新;另外一般使用 比较方便sched.scheduleJob(job, trigger);

        //增
        sched.scheduleJob(trigger);//trigger必须使用forJob绑定JobDetail
        //查
        System.out.println(sched.getTrigger(TriggerKey.triggerKey("trigger1","group1")));//通过TriggerKey获得
        System.out.println(sched.getTriggersOfJob(JobKey.jobKey("job1","group1")));//通过JobKey获得,因为二者是绑定的

        System.out.println(sched.getTriggerGroupNames());//获得所有组名
        System.out.println(sched.getTriggerKeys(GroupMatcher.groupEquals("group1")));//获得组下所有的TriggerKey
        //改
        sched.rescheduleJob(TriggerKey.triggerKey("trigger1","group1"),newTrigger().build()); //更改job的Trigger

        //删
        sched.unscheduleJob(TriggerKey.triggerKey("trigger1","group1"));
