3.2、在对应地方修改自己的项目信息

3.3、选择Web依赖，选中Spring Web、Spring Boot DevTools、Quartz Scheduler。可以选择Spring Boot版本，本次默认为2.3.0，点击Next

3.4、项目结构

四、添加文件

pom.xml文件

quartz.properties文件， 默认使用hikaricp数据源

固定前缀org.quartz

主要分为scheduler、threadPool、jobStore、plugin等部分

org.quartz.scheduler.instanceName=DefaultQuartzScheduler
org.quartz.scheduler.rmi.export=false
org.quartz.scheduler.rmi.proxy=false
org.quartz.scheduler.wrapJobExecutionInUserTransaction = false

实例化ThreadPool时，使用的线程类为SimpleThreadPool

org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool

threadCount和threadPriority将以setter的形式注入ThreadPool实例

并发个数

org.quartz.threadPool.threadCount=5

优先级

org.quartz.threadPool.threadPriority=5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread=true

org.quartz.jobStore.misfireThreshold=5000

默认存储在内存中

org.quartz.jobStore.class=org.quartz.simpl.RAMJobStore

持久化

org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.useProperties=true

org.quartz.jobStore.tablePrefix=QRTZ_
org.quartz.jobStore.dataSource=qzDS

org.quartz.dataSource.qzDS.driver=com.mysql.cj.jdbc.Driver
org.quartz.dataSource.qzDS.provider=hikaricp

使用hikaricp 时URL 大写

org.quartz.dataSource.qzDS.URL=jdbc:mysql://localhost:3306/mybatis?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
org.quartz.dataSource.qzDS.user=root
org.quartz.dataSource.qzDS.password=root
org.quartz.dataSource.qzDS.maxConnections=10

SchedulerConfig.java

注意 定义executorListener后，quartz的配置文件名称不能为默认的quartz.properties ，否则会初始化两次导致失败
package org.ouyushan.springboot.scheduler.quartz.config;

import org.quartz.Scheduler;
import org.springframework.beans.factory.config.PropertiesFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;

import java.io.IOException;
import java.util.Properties;

/**

    */
    @Configuration
    @EnableScheduling
    public class SchedulerConfig {

    @Bean
    public SchedulerFactoryBean schedulerFactory() throws IOException {
    SchedulerFactoryBean factory = new SchedulerFactoryBean();
    factory.setQuartzProperties(quartzProperties());
    return factory;
    }

    @Bean
    public Properties quartzProperties() throws IOException {
    PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
    propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
    //在quartz.properties中的属性被读取并注入后再初始化对象
    propertiesFactoryBean.afterPropertiesSet();
    return propertiesFactoryBean.getObject();
    }

    /**

    • quartz初始化监听器
    • 定义该bean，quartz.properties必须改名
      /
      /       @Bean
      public QuartzInitializerListener executorListener() {
      return new QuartzInitializerListener();
      }*/

    /**

    • 通过SchedulerFactoryBean获取Scheduler的实例
      */
      @Bean
      public Scheduler scheduler() throws IOException {
      return schedulerFactory().getScheduler();
      }
      }

HelloJob.java
package org.ouyushan.springboot.scheduler.quartz.job;

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

import java.time.LocalDateTime;

/**

  • @Description:

  • @Author: ouyushan

  • @Email: ouyushan@hotmail.com

  • @Date: 2020/6/11 16:07
    */
    public class HelloJob implements Job {

    private String name;

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

    @Override
    public void execute(JobExecutionContext context) throws JobExecutionException {
    System.out.println("Hello：" + name + LocalDateTime.now());
    }
    }

HiJob.java

package org.ouyushan.springboot.scheduler.quartz.job;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

import java.time.LocalDateTime;

/**

  • @Description:

  • @Author: ouyushan

  • @Email: ouyushan@hotmail.com

  • @Date: 2020/6/11 16:25
    */
    public class HiJob extends QuartzJobBean {

    private String name;

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

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
    System.out.println("Hi：" + name + LocalDateTime.now());
    }
    }

SpringBootSchedulerQuartzApplication.java

package org.ouyushan.springboot.scheduler.quartz;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class SpringBootSchedulerQuartzApplication {

public static void main(String[] args) {
    SpringApplication.run(SpringBootSchedulerQuartzApplication.class, args);
}

}

五、测试

SpringBootSchedulerQuartzApplicationTests.java
package org.ouyushan.springboot.scheduler.quartz;

import org.junit.jupiter.api.Test;
import org.ouyushan.springboot.scheduler.quartz.job.HelloJob;
import org.quartz.*;
import org.quartz.impl.StdSchedulerFactory;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureWebMvc;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.Date;

@SpringBootTest
@AutoConfigureWebMvc
class SpringBootSchedulerQuartzApplicationTests {

@Test
public void test() throws SchedulerException {
    // 1. 创建工厂类 SchedulerFactory
    SchedulerFactory factory = new StdSchedulerFactory();
    // 2. 通过 getScheduler() 方法获得 Scheduler 实例
    Scheduler scheduler = factory.getScheduler();

    // 3. 使用上文定义的 HelloJob
    JobDetail jobDetail = JobBuilder.newJob(HelloJob.class)
            //job 的name和group
            .withIdentity("jobName", "jobGroup")
            .usingJobData("name","ouyushan")
            .build();

    //3秒后启动任务
    Date statTime = new Date(System.currentTimeMillis() + 3000);

    // 4. 启动 Scheduler
    scheduler.start();

    // 5. 创建Trigger
    //使用SimpleScheduleBuilder或者CronScheduleBuilder
    Trigger trigger = TriggerBuilder.newTrigger()
            .withIdentity("jobTriggerName", "jobTriggerGroup")
            .withSchedule(CronScheduleBuilder.cronSchedule("0/2 * * * * ?")) //两秒执行一次
            .build();

    // 6. 注册任务和定时器
    scheduler.scheduleJob(jobDetail, trigger);

}

}

执行测试用例后
SELECT * FROM mybatis.qrtz_job_details;
表中已记录任务详情数据

解除外键
SET foreign_key_checks = 0

激活外键
SET foreign_key_checks = 1
