3.配置文件quartz.properties

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.scheduler.instanceName = MyScheduler
org.quartz.threadPool.threadCount = 3
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.tablePrefix = QRTZ_
org.quartz.jobStore.dataSource = mysqlDatabase
 
org.quartz.dataSource.mysqlDatabase.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.mysqlDatabase.URL = jdbc:mysql://localhost:3306/quartz?characterEncoding=utf-8
org.quartz.dataSource.mysqlDatabase.user = root
org.quartz.dataSource.mysqlDatabase.password = root
org.quartz.dataSource.mysqlDatabase.maxConnections = 5

4.jobdetail定义

package com.company.basedemo;

import java.util.Date;

import org.apache.commons.lang.time.DateFormatUtils;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.InterruptableJob;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.JobKey;
import org.quartz.UnableToInterruptJobException;

//禁止并发
@DisallowConcurrentExecution
public class HelloJob implements InterruptableJob {

    private boolean stop = false;

    public void execute(JobExecutionContext context) throws JobExecutionException {

        if (stop) {
            
            System.out.println("--stop--");
            
            return;
        }

        String time = DateFormatUtils.format(new Date(), "yyyy-MM-dd HH:mm:ss");
        System.out.println(time);

        JobKey key = context.getJobDetail().getKey();

        JobDataMap dataMap = context.getJobDetail().getJobDataMap();

        String jobSays = dataMap.getString("jobSays");

        float myFloatValue = dataMap.getFloat("myFloatValue");

        System.err.println("instance " + key + "of HelloJob says :" + jobSays
                + ", and val is : " + myFloatValue);
    }

    public void interrupt() throws UnableToInterruptJobException {

        stop = true;

        
    }

}

5.调用使用

package com.company.basedemo;

import java.util.concurrent.TimeUnit;

import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.JobKey;
import org.quartz.ObjectAlreadyExistsException;
import org.quartz.Scheduler;

import org.quartz.SchedulerFactory;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.TriggerKey;
import org.quartz.impl.StdSchedulerFactory;

/**

 *
 */
public class App {
    public static void main(String[] args) throws SchedulerException, InterruptedException {

        SchedulerFactory schedFact = new StdSchedulerFactory();
        Scheduler sched = schedFact.getScheduler();
        sched.start();

        try {
            JobDetail job = JobBuilder.newJob(HelloJob.class)
                    .withIdentity("myJob", "group1")
                    .usingJobData("jobSays", "Hello World!")
                    .usingJobData("myFloatValue", 3.141f)
                    .build();

            Trigger trigger = TriggerBuilder.newTrigger()
                    .withIdentity("myTrigger", "group1")
                    .startNow()
                    .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                            .withIntervalInSeconds(5)
                            .repeatForever())
                    .build();

            sched.scheduleJob(job, trigger);

        } catch (ObjectAlreadyExistsException e) {
            System.err.println("发现任务已经在数据库存在了，直接从数据库里运行:" + e.getMessage());

            //中断执行
            // sched.interrupt(new JobKey("myJob","group1"));

            // sched.unscheduleJob(new TriggerKey("myTrigger","group1"));

            //停止执行
            //sched.pauseJob(new JobKey("myJob","group1"));
        }

        TimeUnit.SECONDS.sleep(16);

        sched.shutdown(true);

        System.out.println("--end--");
    }
}
