持久化quartz解决分布式定时任务的单线程启动，持久化定时任务

通过持久化quartz来实现多节点的单启动，持久化定时启动记录

首先是本quartz是通过持久化数据到数据库来实现控制单点启动，相应的11张数据库表是必不可少。下图就是这11张表。

具体这些表的关系，表的作用和注意点，这篇博文讲的相当好。推荐看下：精进 Quartz—Quartz大致介绍（一）

1.表的脚本：

2.maven引入quartz的相关依赖

        <!--quartz依赖包  start-->
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
        </dependency>

        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz-jobs</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
        </dependency>
        <!--quartz依赖包  end-->

3.quartz的配置文件 quartz.yml

org:
  quartz:
    scheduler:
      instanceName: quartzScheduler
      instanceId: AUTO
    jobStore:
      class: org.quartz.impl.jdbcjobstore.JobStoreTX
      driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
      tablePrefix: QRTZ_
      isClustered: true
      useProperties: false
      clusterCheckinInterval: 20000
    threadPool:
      class: org.quartz.simpl.SimpleThreadPool
      threadCount: 10
      threadPriority: 5
      threadsInheritContextClassLoaderOfInitializingThread: true

4.Quartz调度配置类 ，加载第三步的配置文件。

import org.quartz.CronTrigger;
import org.quartz.JobDetail;
import org.quartz.spi.JobFactory;
import org.quartz.spi.TriggerFiredBundle;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

import javax.annotation.Resource;
import javax.sql.DataSource;
import java.io.IOException;
import java.util.Properties;

/**
 * @author zhanglifeng
 * @Description Quartz调度配置类
 */
@Configuration
public class QuartzSchedulerConfig {
    private static final Logger LOGGER = LoggerFactory.getLogger(QuartzSchedulerConfig.class);
    private static final String QUARTZ_YML_NAME = "/quartz.yml";

    @Resource
    private DataSource dataSource;

    @Bean
    public JobFactory jobFactory(ApplicationContext applicationContext) {
        AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
        jobFactory.setApplicationContext(applicationContext);
        return jobFactory;
    }

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory, CronTrigger[] cronTrigger, JobDetail[] jobDetails) {
        SchedulerFactoryBean factoryBean = new SchedulerFactoryBean();
        try {
            factoryBean.setQuartzProperties(initQuartzYml());
            factoryBean.setDataSource(dataSource);
            factoryBean.setJobFactory(jobFactory);
            factoryBean.setTriggers(cronTrigger);
            factoryBean.setJobDetails(jobDetails);
            factoryBean.setOverwriteExistingJobs(true);
        } catch (Exception e) {
            LOGGER.error("加载{}配置文件失败.", QUARTZ_YML_NAME, e);
            throw new RuntimeException("加载配置文件失败", e);
        }
        return factoryBean;
    }

    @Bean
    public Properties initQuartzYml() throws IOException {
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource(QUARTZ_YML_NAME));
        propertiesFactoryBean.afterPropertiesSet();
        return propertiesFactoryBean.getObject();
    }

    class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements ApplicationContextAware {
        private transient AutowireCapableBeanFactory beanFactory;

        @Override
        public void setApplicationContext(final ApplicationContext context) {
            beanFactory = context.getAutowireCapableBeanFactory();
        }

        @Override
        protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
            final Object job = super.createJobInstance(bundle);
            beanFactory.autowireBean(job);
            return job;
        }
    }
}

到这里，quartz的基本配置完成了。还需要代码中具体的job,task来实现定时任务。贴出项目结构来具体看下

5.定时任务触发器 TradeOrderCompleteJob.java

import org.quartz.JobDetail;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.JobDetailFactoryBean;
import org.springframework.stereotype.Component;
import tp.task.center.zlf.task.TradeOrderCompleteTask;

/**
 * [定时任务触发器配置]
 * @author zhanglifeng
 * @date 20196-11-13
 */
@Component
public class TradeOrderCompleteJob {

    @Bean(name = "jobOrderCompleteTrigger")
    public CronTriggerFactoryBean jobOrderCompleteTrigger(@Qualifier("jobOrderCompleteDetail") JobDetail jobDetail) {
        CronTriggerFactoryBean cronTriggerFactoryBean = new CronTriggerFactoryBean();
        cronTriggerFactoryBean.setJobDetail(jobDetail);
        cronTriggerFactoryBean.setCronExpression("0 0/3 * * * ?");
        return cronTriggerFactoryBean;
    }

    @Bean(name = "jobOrderCompleteDetail")
    public JobDetailFactoryBean jobOrderCompleteDetail(){
        JobDetailFactoryBean jobDetailFactoryBean = new JobDetailFactoryBean();
        jobDetailFactoryBean.setJobClass(TradeOrderCompleteTask.class);
        jobDetailFactoryBean.setDurability(true);
        jobDetailFactoryBean.setRequestsRecovery(true);
        return jobDetailFactoryBean;
    }
}

关系图：

6.任务调度中心

import org.quartz.JobExecutionContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.stereotype.Component;

/**
 * @author zhanglifeng
 */
@Component
public class TradeOrderCompleteTask extends QuartzJobBean {

    private static final Logger LOGGER = LoggerFactory.getLogger(TradeOrderCompleteTask.class);

    @Override
    protected void executeInternal(JobExecutionContext jobExecutionContext) {
        try {
            LOGGER.info("------------------任务开始--------");
            /**
             * 具体业务处理逻辑调用地方
             */
            LOGGER.info("------------------任务结束--------");
        } catch (Exception e) {
            LOGGER.error("----------出错:" + e.getMessage(), e);
        }
    }
}

然后启动项目。即可看到定时任务日志的打印。
