1.maven pom引入依赖

        <!--quartz-->        
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
            <version>2.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
        </dependency>

2.数据库建立quartz相关表

执行quartz建表sql即可。

3.quartz配置文件quartz.properties

# Default Properties file for use by StdSchedulerFactory
# to create a Quartz Scheduler Instance, if a different
# properties file is not explicitly specified.
#
 
org.quartz.scheduler.instanceName: DefaultQuartzScheduler
 
#如果使用集群，instanceId必须唯一，设置成AUTO
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.rmi.export: false
org.quartz.scheduler.rmi.proxy: false
org.quartz.scheduler.wrapJobExecutionInUserTransaction: false
 
org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount: 50
org.quartz.threadPool.threadPriority: 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread: true
org.quartz.jobStore.misfireThreshold: 60000
 
 
#============================================================================
# Configure JobStore
#============================================================================
#
#org.quartz.jobStore.class: org.quartz.simpl.RAMJobStore
#存储方式使用JobStoreTX，也就是数据库
org.quartz.jobStore.class:org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass:org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.useProperties:false
#数据库中quartz表的表名前缀
org.quartz.jobStore.tablePrefix:QRTZ_
org.quartz.jobStore.dataSource:qzDS
#是否使用集群（如果项目只部署到 一台服务器，就不用了）
org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 30000
 
#============================================================================
# Configure Datasources
#============================================================================
#配置数据源
org.quartz.dataSource.qzDS.driver:com.mysql.cj.jdbc.Driver
org.quartz.dataSource.qzDS.URL:jdbc:mysql://localhost:3306/micro_mall?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false
org.quartz.dataSource.qzDS.user:root
org.quartz.dataSource.qzDS.password:`1qazx
org.quartz.dataSource.qzDS.validationQuery=select 0 from dual

此处需说明：org.quartz.jobStore.userProperties值为true时，标记指示着持久性 JobStore 所有在 JobDataMap 中的值都是字符串，因此能以 名-值 对的形式存储，而不用让更复杂的对象以序列化的形式存入 BLOB 列中。

job工厂：

 
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
import org.springframework.stereotype.Component;
 
@Component
public class SpringJobFactory extends AdaptableJobFactory {
 
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;
 
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

        //在quartz.properties中的属性被读取并注入后再初始化对象
        propertiesFactoryBean.afterPropertiesSet();

        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        Properties pro = propertiesFactoryBean.getObject();
        factory.setOverwriteExistingJobs(true);
        factory.setAutoStartup(true);
        factory.setQuartzProperties(pro);
        factory.setJobFactory(springJobFactory);
        return factory;
    }
 
    @Bean
    public Scheduler scheduler() throws IOException{
        return schedulerFactoryBean().getScheduler();
    }
}
