总结

Spring整合Quartz

添加maven配置。
相关配置文件（不管是properties 还是yml。采用JDBC存储）。
创建quartz使用的数据表。
业务逻辑层中使用。
数据表
具体使用

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>

对应的properties 文件

放在resource目录下

# ===========================================================================
# Configure Main Scheduler Properties 调度器属性
# ===========================================================================
#调度标识名 集群中每一个实例都必须使用相同的名称
org.quartz.scheduler.instanceName = DefaultQuartzScheduler
#ID设置为自动获取 每一个必须不同
org.quartz.scheduler.instanceId = AUTO
#============================================================================
# Configure ThreadPool
#============================================================================
#线程池的实现类（一般使用SimpleThreadPool即可满足几乎所有用户的需求）
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
#指定线程数，至少为1（无默认值）(一般设置为1-100直接的整数合适)
org.quartz.threadPool.threadCount = 25
#设置线程的优先级（最大为java.lang.Thread.MAX_PRIORITY 10，最小为Thread.MIN_PRIORITY 1，默认为5）
org.quartz.threadPool.threadPriority = 5
#============================================================================
# Configure JobStore
#============================================================================
# 触发失败阈值，未超过触发时间60s则直接触发，若超过则失火，log信息Handling 1 trigger(s) that missed their scheduled fire-time.
org.quartz.jobStore.misfireThreshold = 60000
#数据保存方式为数据库持久化
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
#数据库代理类，一般org.quartz.impl.jdbcjobstore.StdJDBCDelegate可以满足大部分数据库
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#JobDataMaps是否都为String类型
org.quartz.jobStore.useProperties = false
#表的前缀，默认QRTZ_
org.quartz.jobStore.tablePrefix = QRTZ_
#是否加入集群
org.quartz.jobStore.isClustered = true
#调度实例失效的检查时间间隔
org.quartz.jobStore.clusterCheckinInterval = 20000

配置类

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 {
        //创建SchedulerFactoryBean
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        //设置调度器自动运行
        factory.setAutoStartup(true);
        //设置配置文件位置
        factory.setConfigLocation(new ClassPathResource("/quartz.properties"));
        //设置job工厂，使job可以自动注入
        SpringBeanJobFactory jobFactory = new SpringBeanJobFactory();
        factory.setJobFactory(jobFactory);
        //设置数据源
        factory.setDataSource(dataSource);
        //设置事务
        factory.setTransactionManager(txManager);
        //设置重写已存在的Job
        factory.setOverwriteExistingJobs(true);
        return factory;
    }

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

自定义任务类：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 {
            //使用反射执行spring中的任务
            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("任务执行失败");
        }

    }
}

获取spring中bean的工具类：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;
    }

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

}

定时任务服务接口：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实现类：QuartzServiceImpl

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

        log.info("程序启动 ==> 初始化所有任务开始 ！");
        if (CollectionUtils.isEmpty(quartzTaskList)) {
            scheduler.shutdown();
            return;
        }
        for (QuartzTask quartzTask : quartzTaskList) {
            //判断是否启动状态
            if (quartzTask.getStatus()) {
                this.addJob(quartzTask);
            }
        }
        log.info("程序启动 ==> 初始化所有任务结束 ！");
    }

    @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();
            //构建job信息
            JobDetail jobDetail = JobBuilder.newJob(job.getClass()).withIdentity(taskName, groupName).build();
            //表达式调度构建器(即任务执行的时间)
            /*使用withMisfireHandlingInstructionDoNothing是因为重启项目时之前添加的job都算失火
            ，默认配置withMisfireHandlingInstructionFireAndProceed失火后会立即执行一遍，
            而withMisfireHandlingInstructionDoNothing失火后不会立即执行，而是按照下一个cron执行
            */
            CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cron).withMisfireHandlingInstructionDoNothing();

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

}

ScheduledTaskRunner类

项目启动后获取数据库中的定时任务列表，初始化定时任务

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(" >>>>>> 项目启动完毕, 开启 => 需要自启的任务 开始!");
        List<QuartzTask> activatedTaskList = quartzTaskService.list();
        quartzService.initAllTask(activatedTaskList);
        log.info(" >>>>>> 项目启动完毕, 开启 => 需要自启的任务 结束！");
    }
}

任务实体类：QuartzTask

映射数据库自定义任务表

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 {
    /**
     * 主键
     */
    @TableId(type = IdType.AUTO)
    private Integer id;

    /**
     * 任务名称
     */
    private String taskName;

    /**
     * group名称
     */
    private String groupName;

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

    /**
     * 参数
     */
    private String params;

    /**
     * cron表达式
     */
    private String cron;

    /**
     * 状态
     */
    private Boolean status;

    /**
     * 任务描述
     */
    private String des;
}

任务dao层，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> {
}

任务service层

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实现类

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
{

}

任务controller

package com.anjie.manage.quartz.controller;

具体使用

1、新建具体需要执行任务

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被执行(任务示例)"+param);
    }
}

2、配置定时任务

注意：

1.这里的任务路径是需要执行的类中的方法路径，采用bean的名称 + 方法名（例：task01.test），名称首字母小写，不然会找不到bean，也可以自己给需要执行的任务类bean起名

2.参数是字符串，可以自己写json字符串，是否传参与方法中保持一致，方法中有形参，这里就必传，方法没有形参，这里就不传，不然任务会执行失败

具体效果

spring boot整合quartz实现多个定时任务的方法

最近收到了很多封邮件,都是想知道spring boot整合quartz如何实现多个定时任务的,由于本人生产上并没有使用到多个定时任务,这里给个实现的思路. 1.新建两个定时任务,如下: public class ScheduledJob implements Job{ @Override public void execute(JobExecutionContext context) throws JobExecutionException { System.out.println("sched
Quartz+Spring Boot实现动态管理定时任务

项目实践过程中碰到一个动态管理定时任务的需求:针对每个人员进行信息的定时更新,具体更新时间可随时调整.启动.暂定等. 思路将每个人员信息的定时配置保存到数据库中,这样实现了任务的动态展示和管理.任务的每一次新增或变更,都会去数据库变更信息. 设置一个统一的任务管理器,专门负责动态任务的增删改查. POM依赖 <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://mav

SpringBoot中使用Quartz管理定时任务的方法

定时任务在系统中用到的地方很多,例如每晚凌晨的数据备份,每小时获取第三方平台的 Token 信息等等,之前我们都是在项目中规定这个定时任务什么时候启动,到时间了便会自己启动,那么我们想要停止这个定时任务的时候,就需要去改动代码,还得启停服务器,这是非常不友好的事情直至遇见 Quartz,利用图形界面可视化管理定时任务,使得我们对定时任务的管理更加方便,快捷一.Quartz 简介 Quartz是一个开源的作业调度框架,它完全由Java写成,并设计用于J2SE和J2EE应用中.它提供了巨大的灵
