SpringBoot2.0整合Quartz自动化配置集成

在新版本的SpringBoot2.0发布后，急迫尝鲜的我将相关的项目已经更换为最新版本，在SpringBoot源码GitHub看到更新日志，表明了针对Quartz新版本进行了 AutoConfiguration自动化配置，省去了很多繁琐的配置。

核心代码实现

　　quartz.properties 基本配置属性

###############内存版配置####################################
#org.quartz.scheduler.instanceName=spring-boot-quartz-demo
#org.quartz.scheduler.instanceId=AUTO
#org.quartz.threadPool.threadCount=5
#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
###############集群版配置####################################
org.quartz.scheduler.instanceName=spring-boot-quartz-demo
org.quartz.scheduler.instanceId=AUTO
org.quartz.scheduler.skipUpdateCheck=true
org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount=5
org.quartz.threadPool.threadPriority=5
org.quartz.jobStore.misfireThreshold=60000
org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
#org.quartz.jobStore.dataSource=dataSource
org.quartz.jobStore.tablePrefix=QRTZ_
org.quartz.jobStore.isClustered=true
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.oracle.OracleDelegate
org.quartz.jobStore.useProperties=false

　　QuartzJobFactory.java  注入到Spring 容器

package top.enjoyitlife.config;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;
import org.springframework.stereotype.Component;

@Component
public   class QuartzJobFactory  extends SpringBeanJobFactory{
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;  
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {    
        Object jobInstance = super.createJobInstance(bundle);  
        capableBeanFactory.autowireBean(jobInstance);  
        return jobInstance;
    }  
}

　QuartzConfig.java 配置类加载配置文件对quartz进行实例化和属性设置注意使用集群方案需要连接数据库，而内存版则不用配置数据库

package top.enjoyitlife.config;

import java.io.IOException;
import java.util.Properties;
import javax.sql.DataSource;
import org.quartz.spi.JobFactory;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.ApplicationContext;
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.transaction.PlatformTransactionManager;
@Configuration
public class QuartzConfig {

    public static final String QUARTZ_PROPERTIES_PATH = "/quartz.properties";

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

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory,DataSource dataSource, PlatformTransactionManager transactionManager) throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setAutoStartup(true);
        factory.setJobFactory(jobFactory);
        factory.setQuartzProperties(quartzProperties());
      //集群版配置
        factory.setDataSource(dataSource);
        factory.setTransactionManager(transactionManager);
        return factory;
    }

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

QuartzBindOperationConfig.java 定时任务的绑定包括触发器 CRON表达式备注任务名任务所在组

package top.enjoyitlife.config;

import org.quartz.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import top.enjoyitlife.schedule.TestSchedule;

@Configuration
public class QuartzBindOperationConfig {
    private Logger logger = LoggerFactory.getLogger(getClass());
    @Autowired
    private QuartzJobFactory quartzJobFactory;
    @Autowired
    private Scheduler scheduler;
    public void scheduleBind() {
        try {
            scheduler.setJobFactory(quartzJobFactory);
            JobDetail tesJobDetail = JobBuilder.newJob(TestSchedule.class)
                    .withIdentity("tesJob", "tesJob").withDescription("定时任务demo")
                    .build();
            CronScheduleBuilder tesJobCronScheduleBuilder = CronScheduleBuilder.cronSchedule("0/10 * * * * ?");
            CronTrigger tesJobCronTrigger = TriggerBuilder.newTrigger()
                    .withIdentity("tesJobTrigger", "tesJob")
                    .withSchedule(tesJobCronScheduleBuilder).build();
            scheduler.scheduleJob(tesJobDetail, tesJobCronTrigger);
            scheduler.start();
        } catch (SchedulerException e) {
            // e.printStackTrace();
        }

    }

}

ApplicationListenerConfig.java 项目启动初始化即加载任务

package top.enjoyitlife.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.event.ContextRefreshedEvent;

@Configuration
public class ApplicationListenerConfig implements ApplicationListener<ContextRefreshedEvent> {

    private Logger logger = LoggerFactory.getLogger(getClass());
    @Autowired
    private QuartzBindOperationConfig quartzBindOperationConfig;  
    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {       
        quartzBindOperationConfig.scheduleBind();        
    }

}

TestSchedule.java 测试任务演示类

package top.enjoyitlife.schedule;
import java.util.Date;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@DisallowConcurrentExecution
public class TestSchedule implements Job{
    
     private Logger logger = LoggerFactory.getLogger(getClass());
    
    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
        logger.info("*****"+new Date());
    }
}

运行日志：

修改application.properties 中的server.port端口号，然后重新运行QuartzDistributeApplication的main 方法。以下截图为双服务同时启动时的任务，目前是只有任务1有日志记录，服务2没有任务记录。

停止任务1应用，然后我们会看到任务2 打印以下日志：

【小技巧】

　　如果要手动修改集群中的任务CRON 表达式，需要首先修改表QRTZ_CRON_TRIGGERS中的CRON_EXPRESSION表达式，然后在修改表QRTZ_TRIGGERS中的NEXT_FIRE_TIME和PREV_FIRE_TIME的值为0，在下次任务执行后，该任务的执行间隔就会生效。

　　如果要手动删除集群中的定时任务，删除表记录顺序如下：QRTZ_CRON_TRIGGERS----->QRTZ_TRIGGERS---->QRTZ_JOB_DETAILS,主要由于存在外键的原因，所以要按顺序删除。
