java quartz JobBuilder

JobBuilder主要主要用来创建JobDetail,常用两个属性:

.withIdentity("job1", "group1") //设置job的名称和分组,以便后期的查找
.usingJobData("key","value") // 使用JobData向job中传递参数

完整代码演示:

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("key"));
        }
    }

    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("key","value") // 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")
                .startNow()
                .build();
        sched.scheduleJob(job, trigger);
        sched.start();
    }
}
