一、环境
Idea 2020.1
JDK 1.8
maven
二、目的
spring boot 通过整合quartz
gitHub地址： https://github.com/ouyushan/ouyushan-spring-boot-samples
三、步骤
3.1、点击File -> New Project -> Spring Initializer，点击next

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

4.0.0

org.springframework.boot
spring-boot-starter-parent
2.3.0.RELEASE


org.ouyushan
spring-boot-scheduler-quartz
0.0.1-SNAPSHOT
spring-boot-scheduler-quartz

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;

/**

• @Description:

• @Date: 2020/6/11 15:58
  */
  @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
