SpringBoot 整合Quartz定时任务管理【SpringBoot系列18】

SpringCloud 大型系列课程正在制作中，欢迎大家关注与提意见。
程序员每天的CV 与 板砖，也要知其所以然，本系列课程可以帮助初学者学习 SpringBooot 项目开发 与 SpringCloud 微服务系列项目开发

Quartz是由Java语言编写，是OpenSymphony开源组织在Job scheduling领域的项目。

1 项目信息

首先是在项目的 pom.xml 文件中添加依赖如下

 <!-- 定时任务-->
 <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-quartz -->
 <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-quartz</artifactId>
     <version>2.7.9</version>
 </dependency>

 <dependency>
     <groupId>com.google.code.gson</groupId>
     <artifactId>gson</artifactId>
 </dependency>

然后添加了下定时任务的配置信息

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import javax.sql.DataSource;
import java.util.Properties;

/**
 * 定时任务配置
 *
 * @author 早起的年轻人
 * @since 2.0.0 2023-04-20
 */
@Configuration
public class ScheduleConfig {
    
    

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(DataSource dataSource) {
    
    
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setDataSource(dataSource);

        //quartz参数
        Properties prop = new Properties();
        //#调度器实例名称
        prop.put("org.quartz.scheduler.instanceName", "RenrenScheduler");
        //#调度器实例编号自动生成
        prop.put("org.quartz.scheduler.instanceId", "AUTO");
        //线程池配置
        prop.put("org.quartz.threadPool.class", "org.quartz.simpl.SimpleThreadPool");
        prop.put("org.quartz.threadPool.threadCount", "20");
        prop.put("org.quartz.threadPool.threadPriority", "5");
        //JobStore配置
        prop.put("org.quartz.jobStore.class", "org.springframework.scheduling.quartz.LocalDataSourceJobStore");
        //集群配置 开启分布式部署
        prop.put("org.quartz.jobStore.isClustered", "true");
        prop.put("org.quartz.jobStore.clusterCheckinInterval", "15000");
        prop.put("org.quartz.jobStore.maxMisfiresToHandleAtATime", "1");

        prop.put("org.quartz.jobStore.misfireThreshold", "12000");
        prop.put("org.quartz.jobStore.tablePrefix", "QRTZ_");
        prop.put("org.quartz.jobStore.selectWithLockSQL", "SELECT * FROM {0}LOCKS UPDLOCK WHERE LOCK_NAME = ?");

        //PostgreSQL数据库，需要打开此注释
        //prop.put("org.quartz.jobStore.driverDelegateClass", "org.quartz.impl.jdbcjobstore.PostgreSQLDelegate");
//        prop.put(" org.quartz.jobStore.driverDelegateClass "," org.quartz.impl.jdbcjobstore.StdJDBCDelegate");

        factory.setQuartzProperties(prop);

        factory.setSchedulerName("RenrenScheduler");
        //延时启动
        factory.setStartupDelay(10);
        factory.setApplicationContextSchedulerContextKey("applicationContextKey");
        //可选，QuartzScheduler 启动时更新己存在的Job，这样就不用每次修改targetObject后删除qrtz_job_details表对应记录了
        factory.setOverwriteExistingJobs(true);
        //设置自动启动，默认为true
        factory.setAutoStartup(true);

        return factory;
    }
}

然后添加 Quartz 所需要的表结构

本文章接 SpringBoot ElasticSearch 实现订单的分页查询 【SpringBoot系列17】

2 服务启动时 加载定时任务

ScheduleJobService.java

public interface ScheduleJobService extends IService<ScheduleJobEntity> {
    
    

	/** 保存定时任务*/
	boolean newObj(ScheduleJobEntity scheduleJob);
	
	/**更新定时任务*/
	void update(ScheduleJobEntity scheduleJob);
}

ScheduleJobServiceImpl.java 实现类

@Service("scheduleJobService")
public class ScheduleJobServiceImpl extends ServiceImpl<ScheduleJobDao, ScheduleJobEntity> implements ScheduleJobService {
    
    
    @Resource
    private Scheduler scheduler;

    /**
     * 项目启动时，初始化定时器
     */
    @PostConstruct
    public void init() {
    
    
        //查询当前所有的定时任务
        List<ScheduleJobEntity> scheduleJobList = this.list(new QueryWrapper<>());
        try {
    
    
            scheduler.clear();
        } catch (SchedulerException e) {
    
    
            e.printStackTrace();
        }
        for (ScheduleJobEntity scheduleJob : scheduleJobList) {
    
    
            //获取任务的表达式触发器
            CronTrigger cronTrigger = ScheduleUtils.getCronTrigger(scheduler, scheduleJob.getJobId());
            //如果不存在，则创建
            if (cronTrigger == null) {
    
    
                ScheduleUtils.createScheduleJob(scheduler, scheduleJob);
            } else {
    
    
                ScheduleUtils.updateScheduleJob(scheduler, scheduleJob);
            }
        }
    }
}

新建定时任务与更新定时任务如下：

    @Override
    @Transactional(rollbackFor = Exception.class)
    public boolean newObj(ScheduleJobEntity scheduleJob) {
    
    
        scheduleJob.setCreateTime(new Date());
        //设置状态 默认是启动
        scheduleJob.setStatus(Constant.ScheduleStatus.NORMAL.getValue());
        //cron表达式
        String cronExpression = scheduleJob.getCronExpression();
        //验证
        boolean valid =  CronExpression.isValidExpression(cronExpression);
        if(!valid){
    
    
            throw new RuntimeException("cron 表达式不正确");
        }
        //保存任务
        this.save(scheduleJob);
        //构建job信息
        ScheduleUtils.createScheduleJob(scheduler, scheduleJob);
        return false;
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public void update(ScheduleJobEntity scheduleJob) {
    
    
        ScheduleUtils.updateScheduleJob(scheduler, scheduleJob);
        //更新数据库
        this.updateById(scheduleJob);
    }

ScheduleJobEntity.java 类

import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;
