springboot和quartz整合实现动态定时任务（持久化单节点）

　　Quartz是一个完全由java编写的开源作业调度框架,为在Java应用程序中进行作业调度提供了简单却强大的机制，它支持定时任务持久化到数据库，从而避免了重启服务器时任务丢失，支持分布式多节点，大大的提高了单节点定时任务的容错性。springboot在2.0版本以前没有对quartz做自动配置，因此需要我们自己去手动配置，网上找了许多资料，但是大都不能完全满足自己的需要，因此自己整合了一下方便以后参考（copy），整合代码基于springboot1.5.9和quartz2.3.0，过程如下：

　　2、整合配置类

　　采用jobDetail使用Spring Ioc托管方式来完成整合，我们可以在定时任务实例中使用Spring注入注解完成业务逻辑处理，代码如下

package com.example.demo.config;

import org.quartz.spi.JobFactory;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowire;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
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.annotation.EnableScheduling;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

import javax.sql.DataSource;

@Configuration
@EnableScheduling
public class QuartzConfiguration {
    /**
     * 继承org.springframework.scheduling.quartz.SpringBeanJobFactory
     * 实现任务实例化方式
     */
    public static class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements
            ApplicationContextAware {

        private transient AutowireCapableBeanFactory beanFactory;

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

        /**
         * 将job实例交给spring ioc托管
         * 我们在job实例实现类内可以直接使用spring注入的调用被spring ioc管理的实例
         *
         * @param bundle
         * @return
         * @throws Exception
         */
        @Override
        protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
            final Object job = super.createJobInstance(bundle);
            /**
             * 将job实例交付给spring ioc
             */
            beanFactory.autowireBean(job);
            return job;
        }
    }

    /**
     * 配置任务工厂实例
     *
     * @return
     */
    @Bean
    public JobFactory jobFactory() {
        /**
         * 采用自定义任务工厂 整合spring实例来完成构建任务*/
        AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
        return jobFactory;
    }

    /**
     * 配置任务调度器
     * 使用项目数据源作为quartz数据源
     *
     * @param jobFactory 自定义配置任务工厂
     * @param dataSource 数据源实例
     * @return
     * @throws Exception
     */
    @Bean(destroyMethod = "destroy", autowire = Autowire.NO)
    public SchedulerFactoryBean schedulerFactoryBean(JobFactory jobFactory, DataSource dataSource) throws Exception {
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        //将spring管理job自定义工厂交由调度器维护
        schedulerFactoryBean.setJobFactory(jobFactory);
        //设置覆盖已存在的任务
        schedulerFactoryBean.setOverwriteExistingJobs(true);
        //项目启动完成后，等待2秒后开始执行调度器初始化
        schedulerFactoryBean.setStartupDelay(2);
        //设置调度器自动运行
        schedulerFactoryBean.setAutoStartup(true);
        //设置数据源，使用与项目统一数据源
        schedulerFactoryBean.setDataSource(dataSource);
        //设置上下文spring bean name
        schedulerFactoryBean.setApplicationContextSchedulerContextKey("applicationContext");
        //设置配置文件位置
        schedulerFactoryBean.setConfigLocation(new ClassPathResource("/quartz.properties"));
        return schedulerFactoryBean;
    }
}

　　AutowiringSpringBeanJobFactory：可以看到上面配置类中，AutowiringSpringBeanJobFactory我们继承了SpringBeanJobFactory类，并且通过实现ApplicationContextAware接口获取ApplicationContext设置方法，通过外部实例化时设置ApplicationContext实例对象，在createJobInstance方法内，我们采用AutowireCapableBeanFactory来托管SpringBeanJobFactory类中createJobInstance方法返回的定时任务实例，这样我们就可以在定时任务类内使用Spring Ioc相关的注解进行注入业务逻辑实例了。

　　JobFactory：自定义任务工厂

　　SchedulerFactoryBean：使用项目内部数据源的方式来设置调度器的jobSotre，官方quartz有两种持久化的配置方案。

　　第一种：采用quartz.properties配置文件配置独立的定时任务数据源，可以与使用项目的数据库完全独立。
　　第二种：采用与创建项目统一个数据源，定时任务持久化相关的表与业务逻辑在同一个数据库内。

　　可以根据实际的项目需求采取不同的方案，我采用了第二种方案，在上面配置类中可以看到方法schedulerFactoryBean内自动注入了JobFactory实例，也就是我们自定义的AutowiringSpringBeanJobFactory任务工厂实例，另外一个参数就是DataSource，在我们引入spring-boot-starter-jdbc依赖后会根据application.yml文件内的数据源相关配置自动实例化DataSource实例，这里直接注入是没有问题的。我们通过调用SchedulerFactoryBean对象的setConfigLocation方法来设置quartz定时任务框架的基本配置，配置文件所在位置：resources/quartz.properties => classpath:/quartz.properties下。

　　quartz.properties内容如下：

org.quartz.scheduler.instanceName = schedulerFactoryBean

org.quartz.scheduler.instanceId = AUTO

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.useProperties = false

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool

org.quartz.threadPool.threadCount = 10

org.quartz.threadPool.threadPriority = 5

　　在上面配置中org.quartz.jobStore.class与org.quartz.jobStore.driverDelegateClass是定时任务持久化的关键配置，配置了数据库持久化定时任务以及采用MySQL数据库进行连接，当然你也可以连接别的数据库org.quartz.jobStore.tablePrefix属性配置了定时任务数据表的前缀，在quartz官方提供的创建表SQL脚本默认就是qrtz_，我们需要解压quartz2.3.0的jar，在quartz-2.2.3/docs/dbTables下找到tables_mysql_innodb.sql，然后在mysql客户端执行来创建相应的表。

　　3、动态定时任务demo

　　至此，springboot整合quartz实现动态定时任务和任务持久化完毕，各功能我都测试过，符合预期，具体结果不再贴出，小伙伴们在使用时要注意springboot和quartz的版本问题，很多时候并不是代码有问题，而是jar不匹配。springboot2.0以后，直接有了spring-boot-starter-quartz包，我们只需要把原来的jar替换掉，无需任何配置就完成了整合。
