Quartz 定时任务(2) SpringBoot 整合Quartz 实现定时任务增删改

实现效果: 动态添加, 删除, 更新定时任务

实现方案:

QuartzConfig.java

package com.hejjon.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import java.io.IOException;


@Configuration
public class QuartzConfig {
    
    
    @Autowired
    @Qualifier(value = "taskExecutor")
    private ThreadPoolTaskExecutor threadPoolTaskExecutor;


    @Bean("MySchedulerFactoryBean")
    @Order(2)
    public SchedulerFactoryBean getSchedulerFactoryBean() throws IOException {
        if(threadPoolTaskExecutor == null){
            //logger.error("threadPoolTaskExecutor is null");
            System.exit(0);
        }
        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
        propertiesFactoryBean.setLocation(new ClassPathResource("application.properties"));
        //在quartz.properties中的属性被读取并注入后再初始化对象
        propertiesFactoryBean.afterPropertiesSet();
        //创建SchedulerFactoryBean
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setTaskExecutor(threadPoolTaskExecutor);
        factory.setQuartzProperties(propertiesFactoryBean.getObject());
        //这样当spring关闭时，会等待所有已经启动的quartz job结束后spring才能完全shutdown。
        factory.setWaitForJobsToCompleteOnShutdown(true);
        factory.setOverwriteExistingJobs(false);
        factory.setStartupDelay(1);
        return factory;
    }
    
    
}

ThreadPoolConfig.java

package com.hejjon.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.RejectedExecutionHandler;


@Configuration
public class ThreadPoolConfig {

    @Bean("taskExecutor")
    @Primary
    public ThreadPoolTaskExecutor getThreadPoolTaskExecutor(){
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setMaxPoolSize(5);
        threadPoolTaskExecutor.setCorePoolSize(2);
        RejectedExecutionHandler handler = (r, executor) -> {
            //logger.error("线程池超过最大容量,进行扩容 {} ",executor.getPoolSize());
            executor.setMaximumPoolSize(10);
            Thread thread = new Thread(r);
            thread.start();
            //logger.error(r.toString());
        };
        threadPoolTaskExecutor.setRejectedExecutionHandler(handler);
        return threadPoolTaskExecutor;
    }


}

QuartzTask.java

package com.hejjon.entity;

import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;

import java.io.Serializable;
import java.util.Date;


@Data
@TableName("quartz_task")

    private String cron;

    
    @TableField("status")
    private String status;

    
    @TableField("executeEndtime")
    private Date executeEndtime;

}

QuartzJobManager.java

package com.hejjon.manager;

import com.hejjon.entity.QuartzTask;
import com.hejjon.service.ScheduledJob;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;

import org.springframework.stereotype.Component;


@Component
public class QuartzJobManager {

    @Autowired
    @Qualifier("MySchedulerFactoryBean")
    private SchedulerFactoryBean schedulerFactoryBean;


    
    public void insertJob(QuartzTask task) throws SchedulerException {
        Long taskId = task.getId();
        // 获取调度器
        Scheduler scheduler = schedulerFactoryBean.getScheduler();
        // 执行任务的具体 ScheduledJob 类实现Job接口, 重写execute 方法.
        // 该方法内容是执行定时任务的核心业务
        JobDetail jobDetail = JobBuilder.newJob(ScheduledJob.class)
                .withIdentity("job" + taskId, "group1")
                .build();
        // cron表达式构建器
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(task.getCron());
        // 触发器
        CronTrigger trigger = TriggerBuilder.newTrigger()
                .withIdentity("job" + taskId, "group1")
                .withSchedule(cronScheduleBuilder)
                .build();

        trigger.getJobDataMap().put("taskId", taskId);
        // 交给调度器管理
        scheduler.scheduleJob(jobDetail, trigger);
    }


    
    public void deleteJob(String jobName, String groupName) throws SchedulerException {
        // 获取调度器
        Scheduler scheduler = schedulerFactoryBean.getScheduler();
        scheduler.deleteJob(JobKey.jobKey(jobName, groupName));
    }


    
    public void updateJob(String oldJobName, String oldGroupName, QuartzTask newTask) throws SchedulerException {
        // 先删除再增加一个新的任务
        Scheduler scheduler = schedulerFactoryBean.getScheduler();
        JobKey jobKey = JobKey.jobKey(oldJobName, oldGroupName);
        boolean exists = scheduler.checkExists(jobKey);
        if (exists) {
            scheduler.deleteJob(jobKey);
        }
        insertJob(newTask);
    }
