SpringBoot整合quartz（自启动 job -- 数据库可配置版本）

首先导入配置类（项目启动预加载）

• 背景：项目启动后，SpringBoot 通过数据库配置实现可配置job任务工作，目前的功能算个半自动，更改数据库配置信息的话 就需要重新重启服务了。

    SpringBoot整合quartz（支持多任务和job，支持spring管理）
    框架：SpringBoot + quartz
    
    所需要的依赖：
       <!--quartz-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>
  

• 1.导入配置类

package xxx;

import xxx.entity.ScheduleJob;
import xxx.repository.ScheduleJobRepository;
import org.quartz.SchedulerException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationListener;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import java.util.List;

@Configuration
public class SchedulerListener implements ApplicationListener<ContextRefreshedEvent> {
   
   

    @Autowired
    Scheduler Scheduler;

    @Autowired
    JobFactory JobFactory;

    @Autowired
    ScheduleJobRepository ScheduleJobRepository;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
   
   
    	//数据库查询配置信息  换你自己的逻辑
        List<ScheduleJob> ScheduleJobAll = ScheduleJobRepository.findAll(); 
        try {
   
   
            Scheduler.schedulerJob(ScheduleJobAll);
            System.out.println("SynchronizedData job  start...");
        } catch (SchedulerException | ClassNotFoundException e) {
   
   
            e.printStackTrace();
        }
    }

    @Bean(name ="mySchedulerFactoryBean")
    public SchedulerFactoryBean mySchedulerFactory() {
   
   
        SchedulerFactoryBean bean = new SchedulerFactoryBean();
        bean.setOverwriteExistingJobs(true);
        bean.setStartupDelay(1);
        bean.setJobFactory(JobFactory);
        return bean;
    }
}

• 2.导入应用程序启动时自动扫描并加载的组件1

package xxx.conf.quartz;

import xxx.entity.ScheduleJob;
import lombok.extern.slf4j.Slf4j;
import org.quartz.*;
import org.quartz.impl.StdScheduler;
import org.springframework.context.ApplicationContext;
import org.springframework.stereotype.Component;

import java.util.List;

@Slf4j
@Component
public class Scheduler {
   
   

    public static JobKey getJobKey(String jobId, String jobGroup) {
   
   
        return JobKey.jobKey(jobId, jobGroup);
    }

    public void schedulerJob(List<ScheduleJob> scheduleJobList) throws SchedulerException, ClassNotFoundException {
   
   
        ApplicationContext annotationContext = SpringUtil.getApplicationContext();
        StdScheduler stdScheduler = (StdScheduler) annotationContext.getBean("mySchedulerFactoryBean");//获得上面创建的bean
        org.quartz.Scheduler myScheduler
