1:去官网下载最新的 quartz 解压 在目录 docs\dbTables 下就会找到 tables_mysql.sql 文件、建立数据库Quartz 并导入数据库。

2、导入相应jar包

3、书写QuartzConfig和InvokingJobDetailDetailFactory类

package com.example.demo.task;

import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.quartz.JobDetail;
import org.quartz.Trigger;

import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import java.beans.PropertyVetoException;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;

@Configuration

    private String myDSMaxConnections;


    /**

        prop.put("org.quartz.jobStore.txIsolationLevelSerializable", "true");
        prop.put("org.quartz.jobStore.selectWithLockSQL", "SELECT * FROM {0}LOCKS WHERE LOCK_NAME = ? FOR UPDATE");

        prop.put("org.quartz.threadPool.class", "org.quartz.simpl.SimpleThreadPool");
        prop.put("org.quartz.threadPool.threadCount", "10");
        prop.put("org.quartz.threadPool.threadPriority", "5");

        return prop;
    }

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(@Qualifier("dialogJobTrigger") Trigger cronJobTrigger) throws IOException, PropertyVetoException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        // this allows to update triggers in DB when updating settings in config file:

        factory.setDataSource(createDataSource());
        //注册触发器

        return factory;
    }


    /**
     * 加载job
     * @return
     */
    @Bean()
    public JobDetailFactoryBean updateDialogStatusJobDetail() {
        return createJobDetail(InvokingJobDetailDetailFactory.class, "updateDialogStatusGroup", "dialogJob");
    }

    /**
     * 加载触发器
     * @param jobDetail
     * @return
     */
    @Bean(name = "dialogJobTrigger")
    public CronTriggerFactoryBean dialogStatusJobTrigger(@Qualifier("updateDialogStatusJobDetail") JobDetail jobDetail) {
        return dialogStatusTrigger(jobDetail, "*/5 * * * * ?");
    }



    @Bean
    public ComboPooledDataSource createDataSource() throws PropertyVetoException {
        ComboPooledDataSource dataSource = new ComboPooledDataSource();
        dataSource.setDriverClass(myDSDriver);
        dataSource.setJdbcUrl(myDSURL);
        dataSource.setUser(myDSUser);
        dataSource.setPassword(myDSPassword);
        return dataSource;
    }
    /**
     * 创建job工厂
     * @param jobClass
     * @param groupName
     * @param targetObject
     * @return
     */
    private static JobDetailFactoryBean createJobDetail(Class<?> jobClass, String groupName, String targetObject) {
        JobDetailFactoryBean factoryBean = new JobDetailFactoryBean();
        factoryBean.setJobClass(jobClass);
        factoryBean.setDurability(true);
        factoryBean.setRequestsRecovery(true);
        factoryBean.setGroup(groupName);
        Map<String, String> map = new HashMap<>();
        map.put("targetObject", targetObject);
        map.put("targetMethod", "execute");
        factoryBean.setJobDataAsMap(map);
        return factoryBean;
    }

    /**
     * 创建触发器工厂
     * @param jobDetail
     * @param cronExpression
     * @return
     */
    private static CronTriggerFactoryBean dialogStatusTrigger(JobDetail jobDetail, String cronExpression) {
        CronTriggerFactoryBean factoryBean = new CronTriggerFactoryBean();
        factoryBean.setJobDetail(jobDetail);
        factoryBean.setCronExpression (cronExpression);
        return factoryBean;
    }

}

package com.example.demo.task;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;

import java.lang.reflect.Method;

/**
 * Created by Devin on 2017/7/2.
 */
public class InvokingJobDetailDetailFactory extends QuartzJobBean {

    // 计划任务所在类
    private String targetObject;

    // 具体需要执行的计划任务
    private String targetMethod;

    private ApplicationContext ctx;

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        try {
            Object otargetObject = ctx.getBean(targetObject);
            Method m = null;
            try {
                m = otargetObject.getClass().getMethod(targetMethod);
                m.invoke(otargetObject);
            } catch (SecurityException e) {
                e.printStackTrace();
            } catch (NoSuchMethodException e) {
                e.printStackTrace();
            }
        } catch (Exception e) {
            throw new JobExecutionException(e);
        }
    }

    public void setApplicationContext(ApplicationContext applicationContext) {
        this.ctx = applicationContext;
    }

    public void setTargetObject(String targetObject) {
        this.targetObject = targetObject;
    }

    public void setTargetMethod(String targetMethod) {
        this.targetMethod = targetMethod;
    }
}

4、书写相应的任务DialogJob

package com.example.demo.service;

import org.springframework.stereotype.Service;

/**
 * Created by Devin on 2017/7/2.
 */
@Service("dialogJob")
public class DialogJob {


    // 方法名在quartz定义
    public void execute() throws Exception{

        System.out.println("12345678");

    }
}

5、写配置文件application.properties

quartz.scheduler.instanceName=ServerScheduler
org.quartz.dataSource.myDS.driver=com.mysql.jdbc.Driver
org.quartz.dataSource.myDS.URL=jdbc:mysql://localhost:3306/quartz
org.quartz.dataSource.myDS.user=root
org.quartz.dataSource.myDS.password=root
org.quartz.dataSource.myDS.maxConnections=10

6、执行相应任务，集群环境下面配置多个项目，同一时间只有一个能启动，别的会等待。
