SpringBoot实现定时任务，使用自带的定时任务以及调度框架quartz的配置使用

一. 使用SpringBoot自带的定时任务（适用于小型应用）

创建SpringBoot项目，创建SpringBootTestJob 类，作为定时任务类

 @Component
 @EnableScheduling
 public class SpringBootTestJob {

     @Scheduled(cron = "0/5 * * * * ?") // 每五秒执行一次
     private void test() {
         System.out.println("SpringBootTestJob TEST");
     }
 }

适用性：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

启动后，可以看到，每五秒打印内容：
在这里插入图片描述

二. 使用调度框架quartz（适用于中大型应用）

增加依赖

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

创建定时任务类

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

/**
 * @author SaoE
 * @date 2025/1/19 20:06
 */
public class TestJob implements Job {
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("TestJob TEST");
    }
}

增加quartz配置类QuartzConfig

 @Configuration
 public class QuartzConfig {

     /**
      * 声明一个任务
      * @return
      */
     @Bean
     public JobDetail jobDetail() {
         return JobBuilder.newJob(TestJob.class)
                 .withIdentity("TestJob", "test")
                 .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()
                 .forJob(jobDetail())
                 .withIdentity("trigger", "trigger")
                 .startNow()
                 .withSchedule(CronScheduleBuilder.cronSchedule("*/2 * * * * ?"))
                 .build();
     }
 }

启动主类
可以看到控制台每两秒打印信息：
禁止任务并发执行
任务类增加注解@DisallowConcurrentExecution，修改如下：

@DisallowConcurrentExecution
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");
    }
}

此时打印输出为上一个任务结束后，下一个任务立即开始。如果没有这个注解，则会并发执行。

三、数据库模式quartz的使用

1. 创建数据库表

-- #
-- # 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
-- #

2. 制定一个定时任务

和上面一样的TestJob

@DisallowConcurrentExecution
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");
    }
}

3. 写配置文件

MyJobFactory.java:

@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;
    }
}

SchedulerConfig.java：

@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);
        factory.setJobFactory(myJobFactory);
        factory.setStartupDelay(2);
        return factory;
    }
}

4. 创建接收和相应实体类

接收实体类CronJobReq.java：

public class CronJobReq {
    private String group;

    private String name;

    private String description;

    private String cronExpression;

    @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;
    }
}

响应实体类CronJobResp.java：

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

    private String name;

    private String description;

    private String state;

    private String cronExpression;

    @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;
    }
}

5. 增删改查的controller层接口

任务和quartz通过接口来关联。CronJobReq类的name属性会告诉quartz操作哪个定时任务。

JobController.java:

@RestController
@RequestMapping(value = "/admin/job")
public class JobController {

    private static Logger LOG = LoggerFactory.getLogger(JobController.class);

    @Autowired
    private SchedulerFactoryBean schedulerFactoryBean;

    @RequestMapping(value = "/run")
    public CommonResp<Object> run(@RequestBody CronJobReq cronJobReq) throws SchedulerException {
        String jobClassName = cronJobReq.getName();
        String jobGroupName = cronJobReq.getGroup();
        LOG.info("手动执行任务开始：{}, {}", jobClassName, jobGroupName);
        schedulerFactoryBean.getScheduler().triggerJob(JobKey.jobKey(jobClassName, jobGroupName));
        return new CommonResp<>();
    }

    @RequestMapping(value = "/add")
    public CommonResp add(@RequestBody CronJobReq cronJobReq) {
        String jobClassName = cronJobReq.getName();
        String jobGroupName = cronJobReq.getGroup();
        String cronExpression = cronJobReq.getCronExpression();
        String description = cronJobReq.getDescription();
        LOG.info("创建定时任务开始：{}，{}，{}，{}", jobClassName, jobGroupName, cronExpression, description);
        CommonResp commonResp = new CommonResp();

        try {
            // 通过SchedulerFactory获取一个调度器实例
            Scheduler sched = schedulerFactoryBean.getScheduler();

            // 启动调度器
            sched.start();

            //构建job信息
            JobDetail jobDetail = JobBuilder.newJob((Class<? extends Job>) Class.forName(jobClassName)).withIdentity(jobClassName, jobGroupName).build();

            //表达式调度构建器(即任务执行的时间)
            CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExpression);

            //按新的cronExpression表达式构建一个新的trigger
            CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(jobClassName, jobGroupName).withDescription(description).withSchedule(scheduleBuilder).build();

            sched.scheduleJob(jobDetail, trigger);

        } catch (SchedulerException e) {
            LOG.error("创建定时任务失败:" + e);

{
  "name": "com.mystudy.train.batch.job.TestJob",
  "jobGroupName": "default",
  "cronExpression": "*/2 * * * * ?",
  "desc": "test job"
}

###

GET http://localhost:8000/batch/admin/job/query

###
