6 SpringBoot 完全整合 Quartz 的简单例子

本例是 SpringBoot 完全整合 Quartz 的一个完整例子，基本不需要其他过多配置：

• 基本的实现效果: 对定时任务的 自定义逻辑、启动、暂停、恢复、删除、修改。

• 本例子中的测试 url：
  访问 http://localhost:8080/startHelloWorldJob 启动一个名为 HelloWorld，组名为 GroupOne 的定时任务，每隔 2 秒打印 “hello world”

  • 访问 http://localhost:8080/pauseHelloWorldJob 暂停这个 HelloWorld 的定时任务
  • 访问 http://localhost:8080/resumeHelloWorldJob 恢复这个 HelloWorld 的定时任务
  • 访问 http://localhost:8080/deleteHelloWorldJob 删除这个 HelloWorld 的定时任务
  • 访问 http://localhost:8080/modifyHelloWorldJobCron 修改这个 HelloWorld 的定时任务，修改之后，每隔 5 秒打印 “hello world”

• 在你启动该应用之前：

  • 请自行修改数据库配置：application.yml
  • 请准备Quartz的元数据表：quartz_innodb.sql

2 数据库脚本 quartz_innodb.sql

-- in your Quartz properties file, you'll need to set org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
-- 你需要在你的quartz.properties文件中设置org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
-- StdJDBCDelegate说明支持集群，所有的任务信息都会保存到数据库中，可以控制事物，还有就是如果应用服务器关闭或者重启，任务信息都不会丢失，并且可以恢复因服务器关闭或者重启而导致执行失败的任务

4 启动项

package cn.ys.quartz;

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

@SpringBootApplication
public class QuartzSimpleApp {

    public static void main(String[] args) {

        SpringApplication.run(QuartzSimpleApp.class);
    }
}

5 创建定时任务的实体

package cn.ys.quartz.pojo;

import lombok.Builder;
import lombok.Data;
import org.quartz.Job;
import org.quartz.JobKey;

import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
import java.util.Map;

/**
 * Quartz 里面 一个最简单,最基本的定时任务 应该包含以下必要基本属性
 * 注意 : 这里只是方便演示,故写此类进行简单说明, 可针对自身业务对此类进行扩展
 */
@Data
@Builder
public class TaskDefine {

    /**
     * 定时任务 的名字和分组名 JobKey,{@link org.quartz.JobKey}
     */
    @NotNull(message = "定时任务的 名字 和 组名 坚决不为空")
    private JobKey jobKey;

    /**
     * 定时任务 的描述(可以定时任务本身的描述,也可以是触发器的)
     * {@link org.quartz.JobDetail} description ; {@link org.quartz.Trigger} description
     */
    private String description;

    /**
     * 定时任务 的执行cron (Trigger的CronScheduleBuilder 的cronExpression)
     * {@link org.quartz.Trigger} CronScheduleBuilder {@link org.quartz.CronScheduleBuilder}
     */
    @NotEmpty(message = "定时任务的执行cron 不能为空")
    private String cronExpression;

    /**
     * 定时任务 的元数据
     * {@link org.quartz.JobDataMap}
     */
    private Map<?, ?> jobDataMap;

    /**
     * 定时任务 的 具体执行逻辑类
     * {@link org.quartz.Job}
     */
    @NotNull(message = "定时任务的具体执行逻辑类 坚决不能为空")
    private Class<? extends Job> jobClass;
}

6 创建定时任务的具体执行逻辑

package cn.ys.quartz.execute;

import lombok.extern.slf4j.Slf4j;
import org.quartz.DisallowConcurrentExecution;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
import java.util.Date;

/**
 * Job 是 定时任务的具体执行逻辑
 * JobDetail 是 定时任务的定义
 */
@Slf4j
@DisallowConcurrentExecution
public class SayHelloJobLogic implements Job {

    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {

        String time = LocalDateTime.ofInstant(
                new Date().toInstant(),
                ZoneId.systemDefault()).format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));

        //写你自己的逻辑
        log.info(time + " : SayHelloJob.execute , hello world  ! ");

    }
}

7 创建业务层

package cn.ys.quartz.service;

import lombok.extern.slf4j.Slf4j;
import cn.ys.quartz.pojo.TaskDefine;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.stereotype.Service;

import java.util.Map;

/**
 * Created by EalenXie on 2019/7/10 13:49.
