（企业 / 公司项目）如何使用分布式任务调度框架Quartz集成和 SpringBoot自带的定时任务集成？

2023-12-24 21:31:32

SpringBoot自带的定时任务

首先在你的微服务项目中创建一个新的模块，定时调度模块

?pom.xml里面关联公共模块common的依赖其他不需要改变

?然后启动类别删，启动项目是否报错，写一个简单的测试类访问路径是否成功

package com.jiawa.train.batch.controller;

import com.jiawa.train.batch.feign.BusinessFeign;
import jakarta.annotation.Resource;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {


    @Resource
    BusinessFeign businessFeign;

    @GetMapping("/hello")
    public String hello() {
        return "Hello World! Batch!";
    }
}

创建一个包job 创建类 SpringBootTestJob.java

 package com.jiawa.train.batch.job;

 import org.springframework.scheduling.annotation.EnableScheduling;
 import org.springframework.scheduling.annotation.Scheduled;
 import org.springframework.stereotype.Component;

 /**
  * 适合单体应用，不适合集群
  * 没法实时更改定时任务状态和策略
  */
 @Component
 @EnableScheduling // 开启定时任务
 public class SpringBootTestJob {

     @Scheduled(cron = "0/5 * * * * ?")//   每5秒执行一次 每5秒执行一次 cron 从左到右空格隔开：秒 分钟 小时 日期 月份 星期
     private void test() {
         // 增加分布式锁，解决集群问题
         System.out.println("SpringBootTestJob TEST");
     }
 }

多个定时任务就写多个@Scheduled，定时任务的三要素也要知道：1. 执行的内容：功能逻辑 2. 执行的策略： cron表达式? 3. 开关：开启定时任务

SpringBoot自带的定时任务缺点：? 无法实时更改任务状态，就是当我想把定时任务暂停一下今天的数据有问题，但是这个就无法进行暂停所以用专业的任务调度的框架。

SpringBoot自带的定时任务优点：??开发速度快适合小型的项目，两个注解就好了

分布式任务调度框架Quartz集成

首先导入依赖pom.xml。这里没有版本是因为我的这个是子模块版本由父模块控制

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

跟着思路来导入了依赖之后我们就开始声明我们的任务了，创建一个配置类 quartzConfig? ?触发器就是调用前面声明的任务方法来定时

 package com.jiawa.train.batch.config;

 import com.jiawa.train.batch.job.TestJob;
 import org.quartz.*;
 import org.springframework.context.annotation.Bean;
 import org.springframework.context.annotation.Configuration;

 @Configuration
 public class QuartzConfig {

     /**
      * 声明一个任务
      * @return
      */
     @Bean
     public JobDetail jobDetail() {
         return JobBuilder.newJob(TestJob.class)
                 .withIdentity("TestJob", "test")//  任务名称和组构成任务key
                 .storeDurably()
                 .build();
     }

     /**
      * 声明一个触发器，什么时候触发这个任务
      * @return
      */
     @Bean
     public Trigger trigger() {
         return TriggerBuilder.newTrigger()// 创建一个新的触发器
                 .forJob(jobDetail()) // 将任务detail作为触发器要触发的任务
                 .withIdentity("trigger", "trigger")    // 为触发器设置一个唯一标识，例如 "trigger" 和 "trigger"
                 .startNow()  // 立即触发任务，从当前时间开始
                 .withSchedule(CronScheduleBuilder.cronSchedule("*/2 * * * * ?"))  // 设置触发器的调度规则，使用 cron 格式的字符串，表示每隔 2 分钟触发一次任务
                 .build();
     }
 }

上面代码写了注释的，任务名称TestJob这里就创建一个任务来对应，实现的是Job是框架quartz里面的接口

@DisallowConcurrentExecution // ?禁止并发执行

package com.jiawa.train.batch.job;

import org.quartz.DisallowConcurrentExecution;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

@DisallowConcurrentExecution //  禁止并发执行
public class TestJob implements Job {

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("TestJob TEST开始");
        // try {
        //     Thread.sleep(3000);
        // } catch (InterruptedException e) {
        //     e.printStackTrace();
        // }
        System.out.println("TestJob TEST结束");
    }
}

?这就集成了框架的使用，springboot自带的定时任务也在使用。前面是简单的使用

在项目中集成框架

数据库配置quartz框架调度任务，官方提供的数据库MySQL，创建这几张表记得分库

#
# Quartz seems to work best with the driver mm.mysql-2.0.7-bin.jar
#
# PLEASE consider using mysql with innodb tables to avoid locking issues
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

创建两个固定的配置类，这两个类在任何项目中可以使用都是差不多的固定写法

MyJobFactory.java

package com.jiawa.train.batch.config;

import jakarta.annotation.Resource;
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;
import org.springframework.stereotype.Component;

@Component
public class MyJobFactory extends SpringBeanJobFactory {

    @Resource
    private AutowireCapableBeanFactory beanFactory;

    /**
     * 这里覆盖了super的createJobInstance方法，对其创建出来的类再进行autowire。
     */
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        beanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

创建一个config工具类，根据数据库进行调度任务连接数据库指定定时时间。调度器

package com.jiawa.train.batch.config;

import jakarta.annotation.Resource;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

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

@Configuration
public class SchedulerConfig {

    @Resource
    private MyJobFactory myJobFactory;

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(@Qualifier("dataSource") DataSource dataSource) throws IOException {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        factory.setDataSource(dataSource);// 连接数据库
        factory.setJobFactory(myJobFactory);// 指定前面创建的配置类
        factory.setStartupDelay(2); //  延迟2秒启动
        return factory;
    }
}

?接下来开始完成定时任务的接口，使得定时任务让接口来控制，首先创建请求数据request

package com.jiawa.train.batch.req;

public class CronJobReq {
    private String group; // 分组

    private String name;//   任务名称

    private String description;//  描述

    private String cronExpression;//  执行时间表达式

    @Override
    public String toString() {
        final StringBuffer sb = new StringBuffer("CronJobDto{");
        sb.append("cronExpression='").append(cronExpression).append('\'');
        sb.append(", group='").append(group).append('\'');
        sb.append(", name='").append(name).append('\'');
        sb.append(", description='").append(description).append('\'');
        sb.append('}');
        return sb.toString();
    }

    public String getGroup() {
        return group;
    }

    public void setGroup(String group) {
        this.group = group;
    }

    public String getCronExpression() {
        return cronExpression;
    }

    public void setCronExpression(String cronExpression) {
        this.cronExpression = cronExpression;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

设置响应数据类response，进行set和get

package com.jiawa.train.batch.resp;

import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonInclude;

import java.util.Date;

@JsonInclude(JsonInclude.Include.NON_EMPTY)
public class CronJobResp {
    private String group;// 分组

    private String name; // 任务名称

    private String description; // 描述

    private String state;// 状态

    private String cronExpression;// 定时任务表达式

    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
    private Date nextFireTime;// 

    @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")
    private Date preFireTime;// 

    @Override
    public String toString() {
        final StringBuffer sb = new StringBuffer("CronJobDto{");
        sb.append("cronExpression='").append(cronExpression).append('\'');
        sb.append(", group='").append(group).append('\'');
        sb.append(", name='").append(name).append('\'');
        sb.append(", description='").append(description).append('\'');
        sb.append(", state='").append(state).append('\'');
        sb.append(", nextFireTime=").append(nextFireTime);
        sb.append(", preFireTime=").append(preFireTime);
        sb.append('}');
        return sb.toString();
    }

    public String getGroup() {
        return group;
    }

    public void setGroup(String group) {
        this.group = group;
    }

    public String getCronExpression() {
        return cronExpression;
    }

    public void setCronExpression(String cronExpression) {
        this.cronExpression = cronExpression;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Date getNextFireTime() {
        return nextFireTime;
    }

    public void setNextFireTime(Date nextFireTime) {
        this.nextFireTime = nextFireTime;
    }

    public Date getPreFireTime() {
        return preFireTime;
    }

    public void setPreFireTime(Date preFireTime) {
        this.preFireTime = preFireTime;
    }

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }
}

?创建controller类接口，实现对定时任务的控制返回状态添加定时任务。当然如果项目中有一个控台端这就是控台的接口

创建定时任务，暂停，重置，启动定时任务，删除以及查看总共有多少个定时任务打开

package com.jiawa.train.batch.controller;
