springboot整合quartz定時任務框架的完整步驟

 更新時間：2022年01月13日 16:18:24   作者：蔚藍色的咸魚  
在做項目時有時候會有定時器任務的功能,比如某某時間應該做什么,多少秒應該怎么樣之類的,下面這篇文章主要給大家介紹了關于springboot整合quartz定時任務框架的相關資料,需要的朋友可以參考下

Spring整合Quartz

  1. 添加maven配置。
  2. 相關配置文件（不管是properties 還是yml。采用JDBC存儲）。
  3. 創(chuàng)建quartz使用的數據表。
  4. 業(yè)務邏輯層中使用。
  5. 數據表
  6. 具體使用

pom文件

如下所示：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>

對應的properties 文件

放在resource目錄下

# ===========================================================================
# Configure Main Scheduler Properties 調度器屬性
# ===========================================================================
#調度標識名 集群中每一個實例都必須使用相同的名稱
org.quartz.scheduler.instanceName = DefaultQuartzScheduler
#ID設置為自動獲取 每一個必須不同
org.quartz.scheduler.instanceId = AUTO
#============================================================================
# Configure ThreadPool
#============================================================================
#線程池的實現類（一般使用SimpleThreadPool即可滿足幾乎所有用戶的需求）
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
#指定線程數，至少為1（無默認值）(一般設置為1-100直接的整數合適)
org.quartz.threadPool.threadCount = 25
#設置線程的優(yōu)先級（最大為java.lang.Thread.MAX_PRIORITY 10，最小為Thread.MIN_PRIORITY 1，默認為5）
org.quartz.threadPool.threadPriority = 5
#============================================================================
# Configure JobStore
#============================================================================
# 觸發(fā)失敗閾值，未超過觸發(fā)時間60s則直接觸發(fā)，若超過則失火，log信息Handling 1 trigger(s) that missed their scheduled fire-time.
org.quartz.jobStore.misfireThreshold = 60000
#數據保存方式為數據庫持久化
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
#數據庫代理類，一般org.quartz.impl.jdbcjobstore.StdJDBCDelegate可以滿足大部分數據庫
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#JobDataMaps是否都為String類型
org.quartz.jobStore.useProperties = false
#表的前綴，默認QRTZ_
org.quartz.jobStore.tablePrefix = QRTZ_
#是否加入集群
org.quartz.jobStore.isClustered = true
#調度實例失效的檢查時間間隔
org.quartz.jobStore.clusterCheckinInterval = 20000

配置類

package com.anjie.manage.quartz;

import org.quartz.Scheduler;
import org.springframework.beans.factory.annotation.Autowired;
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.scheduling.quartz.SpringBeanJobFactory;
import org.springframework.transaction.PlatformTransactionManager;

import javax.sql.DataSource;
import java.io.IOException;

@Configuration
public class QuartzConfig {
    @Autowired
    private DataSource dataSource;

    @Autowired
    private PlatformTransactionManager txManager;

    @Bean(name = "quartzScheduler")
    public SchedulerFactoryBean quartzScheduler() throws IOException {
        //創(chuàng)建SchedulerFactoryBean
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        //設置調度器自動運行
        factory.setAutoStartup(true);
        //設置配置文件位置
        factory.setConfigLocation(new ClassPathResource("/quartz.properties"));
        //設置job工廠，使job可以自動注入
        SpringBeanJobFactory jobFactory = new SpringBeanJobFactory();
        factory.setJobFactory(jobFactory);
        //設置數據源
        factory.setDataSource(dataSource);
        //設置事務
        factory.setTransactionManager(txManager);
        //設置重寫已存在的Job
        factory.setOverwriteExistingJobs(true);
        return factory;
    }

    @Bean(name = "scheduler")
    public Scheduler scheduler() throws IOException {
        return quartzScheduler().getScheduler();
    }
}

自定義任務類：ScheduledTask

package com.anjie.manage.quartz;

import com.anjie.auth.common.exception.BadConfigurationException;
import com.anjie.manage.common.SpringContextUtil;
import lombok.Setter;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.springframework.context.ApplicationContext;

import java.lang.reflect.Method;

@Slf4j
@Setter
public class ScheduledTask implements Job {

    private Integer id;

    private String params;

    private String serviceBeanName;

    private String methodName;

    @Override
    public void execute(JobExecutionContext jobExecutionContext) {
        try {
            //使用反射執(zhí)行spring中的任務
            ApplicationContext wac = SpringContextUtil.getApplicationContext();
            Class<?> serviceBean = wac.getBean(serviceBeanName).getClass();
            if (StringUtils.isNotEmpty(params)){
                Method method = serviceBean.getDeclaredMethod(methodName,String.class);
                method.invoke(wac.getBean(serviceBean),params);
            }else {
                Method method = serviceBean.getDeclaredMethod(methodName,null);
                method.invoke(wac.getBean(serviceBean),null);
            }
        }catch (Exception e){
            throw new BadConfigurationException("任務執(zhí)行失敗");
        }

    }
}

獲取spring中bean的工具類：SpringContextUtil

package com.anjie.manage.common;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class SpringContextUtil implements ApplicationContextAware {
    private static ApplicationContext applicationContext = null;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringContextUtil.applicationContext = applicationContext;
    }

    /**
     * 獲取applicationContext
     * @return
     */
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }


}

定時任務服務接口：QuartzService

package com.anjie.manage.quartz.service;

import com.anjie.manage.quartz.entity.po.QuartzTask;

import java.util.List;

public interface QuartzService {
    void initAllTask(List<QuartzTask> scheduledTaskBeanList) throws Exception;

    void addJob(QuartzTask scheduledTask);

    void updateJob(QuartzTask quartzTask);

    void deleteJob(QuartzTask quartzTask);

    void runJobOnce(QuartzTask quartzTask);
}

QuartzService實現類：QuartzServiceImpl

package com.anjie.manage.quartz.service.impl;

import com.anjie.manage.quartz.entity.po.QuartzTask;
import com.anjie.manage.quartz.ScheduledTask;
import com.anjie.manage.quartz.service.QuartzService;

@Slf4j
public class QuartzServiceImpl implements QuartzService {
    @Autowired
    private Scheduler scheduler;

    @Override
    public void initAllTask(List<QuartzTask> quartzTaskList) throws Exception {
        log.info("程序啟動 ==> 初始化所有任務開始 ！");
        if (CollectionUtils.isEmpty(quartzTaskList)) {
            scheduler.shutdown();
            return;
        }
        for (QuartzTask quartzTask : quartzTaskList) {
            //判斷是否啟動狀態(tài)
            if (quartzTask.getStatus()) {
                this.addJob(quartzTask);
            }
        }
        log.info("程序啟動 ==> 初始化所有任務結束 ！");
    }

    @Override
    public void addJob(QuartzTask quartzTask) {
        String taskName = quartzTask.getTaskName();
        String groupName = quartzTask.getGroupName();
        String cron = quartzTask.getCron();
        TriggerKey triggerKey = TriggerKey.triggerKey(taskName, groupName);
        try {
            boolean result = scheduler.checkExists(triggerKey);
            //job已存在，直接返回
            log.info("checkExists quartTask = {} , result = {}", quartzTask, result);
            if (result) {
                return;
            }
            Job job = new ScheduledTask();
            //構建job信息
            JobDetail jobDetail = JobBuilder.newJob(job.getClass()).withIdentity(taskName, groupName).build();
            //表達式調度構建器(即任務執(zhí)行的時間)
            /*使用withMisfireHandlingInstructionDoNothing是因為重啟項目時之前添加的job都算失火
            ，默認配置withMisfireHandlingInstructionFireAndProceed失火后會立即執(zhí)行一遍，
            而withMisfireHandlingInstructionDoNothing失火后不會立即執(zhí)行，而是按照下一個cron執(zhí)行
            */
            CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cron).withMisfireHandlingInstructionDoNothing();
            //按新的cronExpression表達式構建一個新的trigger
            CronTrigger trigger = TriggerBuilder.newTrigger().startNow().withIdentity(taskName, groupName).withSchedule(scheduleBuilder).build();

            String[] serviceBean = quartzTask.getJobClass().split("\\.");
            //獲得JobDataMap，寫入數據

            scheduler.scheduleJob(jobDetail, trigger);
            log.info("addJob quartTask = {} is success", quartzTask);
        } catch (Exception e) {

            log.error("run job quartTask = {} is fail, msg = {}", quartzTask, e);
        }
    }
}

ScheduledTaskRunner類

項目啟動后獲取數據庫中的定時任務列表，初始化定時任務

package com.anjie.manage.quartz;

import com.anjie.manage.quartz.entity.po.QuartzTask;
import com.anjie.manage.quartz.service.QuartzService;
import com.anjie.manage.quartz.service.QuartzTaskService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

import java.util.List;

@Component
@Order(value = 1)
@Slf4j
public class ScheduledTaskRunner implements ApplicationRunner {
    @Autowired
    private QuartzTaskService quartzTaskService;

    @Autowired
    private QuartzService quartzService;

    @Override
    public void run(ApplicationArguments args) throws Exception {
        log.info(" >>>>>> 項目啟動完畢, 開啟 => 需要自啟的任務 開始!");
        List<QuartzTask> activatedTaskList = quartzTaskService.list();
        quartzService.initAllTask(activatedTaskList);
        log.info(" >>>>>> 項目啟動完畢, 開啟 => 需要自啟的任務 結束！");
    }
}

任務實體類：QuartzTask

映射數據庫自定義任務表

package com.anjie.manage.quartz.entity.po;

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

@Data
@TableName(value = "quartz_task")
public class QuartzTask {
    /**
     * 主鍵
     */
    @TableId(type = IdType.AUTO)
    private Integer id;

    /**
     * 任務名稱
     */
    private String taskName;

    /**
     * group名稱
     */
    private String groupName;

    /**
     * job所在類
     */
    private String jobClass;

    /**
     * 參數
     */
    private String params;

    /**
     * cron表達式
     */
    private String cron;

    /**
     * 狀態(tài)
     */
    private Boolean status;

    /**
     * 任務描述
     */
    private String des;
}

任務dao層，我是用的是mybatis-plus

package com.anjie.manage.quartz.dao;

import com.anjie.manage.quartz.entity.po.QuartzTask;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

@Repository
@Mapper
public interface QuartzTaskDao extends BaseMapper<QuartzTask> {
}

任務service層

package com.anjie.manage.quartz.service;


import com.anjie.manage.quartz.entity.po.QuartzTask;
import com.baomidou.mybatisplus.extension.service.IService;

public interface QuartzTaskService extends IService<QuartzTask> {
}

service實現類

package com.anjie.manage.quartz.service.impl;

import com.anjie.manage.quartz.entity.po.QuartzTask;
import com.anjie.manage.quartz.dao.QuartzTaskDao;
import com.anjie.manage.quartz.service.QuartzTaskService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;

@Service
public class QuartzTaskServiceImpl
        extends ServiceImpl<QuartzTaskDao, QuartzTask>
        implements QuartzTaskService
{

具體使用

1、新建具體需要執(zhí)行任務

package com.anjie.manage.quartz;

import com.anjie.manage.quartz.service.QuartzTaskService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class Task01 {
    @Autowired
    private QuartzTaskService quartzTaskService;

    public void test(String param){
        quartzTaskService.list();
        System.out.println("test01被執(zhí)行(任務示例)"+param);
    }
}

2、配置定時任務

注意：

1.這里的任務路徑是需要執(zhí)行的類中的方法路徑，采用bean的名稱 + 方法名（例：task01.test），名稱首字母小寫，不然會找不到bean，也可以自己給需要執(zhí)行的任務類bean起名

2.參數是字符串，可以自己寫json字符串，是否傳參與方法中保持一致，方法中有形參，這里就必傳，方法沒有形參，這里就不傳，不然任務會執(zhí)行失敗

具體效果
