1. pom文件添加依赖

2. yml配置

spring:

datasource:

url: jdbc:mysql://localhost:3306/aipyun?serverTimezone=GMT&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true

username: root

password: root123

driver-class-name: com.mysql.jdbc.Driver

type: com.alibaba.druid.pool.DruidDataSource

druid:

initialSize: 2

minIdle: 2

maxActive: 30

#StatViewServlet:

#loginUsername: admin

#loginPassword: admin

quartz:

#相关属性配置

properties:

org:

quartz:

scheduler:

instanceName: DefaultQuartzScheduler

instanceId: AUTO

jobStore:

class: org.quartz.impl.jdbcjobstore.JobStoreTX

driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate

tablePrefix: QRTZ_

isClustered: false

clusterCheckinInterval: 10000

useProperties: true

threadPool:

class: org.quartz.simpl.SimpleThreadPool

threadCount: 10

threadPriority: 5

threadsInheritContextClassLoaderOfInitializingThread: true

dataSource:

default:

URL: jdbc:mysql://localhost:3306/aipyun?characterEncoding=utf-8

user: root

password: root123

driver: com.mysql.jdbc.Driver

#数据库方式

job-store-type: jdbc

#初始化表结构

#jdbc:

#initialize-schema: never

我们可以对比下这个配置文件和之前的quartz.properties的区别，基本一模一样，只不过写的格式不一样而已。

3. 业务逻辑代码

/*** 删除job

*

*@paramtriggerName 触发器名称

*@paramtriggerGroup 触发器分组

*@paramjobName 任务名称

*@paramjobGroup 任务分组

*@throwsSchedulerException*/

public void deleteJob(String triggerName, String triggerGroup, String jobName, String jobGroup) throwsSchedulerException {

TriggerKey triggerKey=TriggerKey.triggerKey(triggerName, triggerGroup);

scheduler.pauseTrigger(triggerKey);

scheduler.unscheduleJob(triggerKey);

JobKey jobKey=JobKey.jobKey(jobName, jobGroup);

scheduler.deleteJob(jobKey);

}/*** 修改定时任务

*

*@paramoldTriggerKey 需要修改的TriggerKey 也就是唯一标识

*@paramcron 新的cron表达式*/

public voidupdateJob(TriggerKey oldTriggerKey, String cron) {

CronScheduleBuilder scheduleBuilder=CronScheduleBuilder.cronSchedule(cron);

CronTrigger cronTrigger=TriggerBuilder.newTrigger()

.withIdentity(oldTriggerKey).withSchedule(scheduleBuilder).build();try{

scheduler.rescheduleJob(oldTriggerKey, cronTrigger);

}catch(SchedulerException e) {

e.printStackTrace();

}

}/*** 新增job任务

*

*@paramjobName job名称

*@paramjobGroupName job分组名称

*@paramtriggerName 触发器名称

*@paramtriggerGroupName 触发器分组名称

*@paramjobClass 需要执行的job.class

*@paramcron cron 表达式

*@throwsSchedulerException*/

public voidaddJob(String jobName, String jobGroupName,

String triggerName, String triggerGroupName, Class jobClass, String cron)throwsSchedulerException {

CronScheduleBuilder cronScheduleBuilder=CronScheduleBuilder.cronSchedule(cron);

JobDetail jobDetail=JobBuilder.newJob(jobClass).withIdentity(jobName, jobGroupName).build();

Trigger trigger=TriggerBuilder.newTrigger().withIdentity(triggerName, triggerGroupName)

.withSchedule(cronScheduleBuilder).build();

scheduler.scheduleJob(jobDetail, trigger);

}

关于spring-boot-starter-quartz

鄙人用的开发工具是idea，可以直接查看源码，至于用eclispe的怎么查看源码我就不知道了。

我们找到Idea的External Libraries并且展开spring-boot-autoconfigure-2.0.0.RELEASE.jar，找到org.springframework.boot.autoconfigure.quartz，该目录就是SpringBoot为我们提供的Quartz自动化配置源码实现，在该目录下有如下所示几个类：

QuartzAutoConfiguration该类是自动配置的主类，内部配置了SchedulerFactoryBean，相当于我们之前自己配的SchedulerFactoryBean类。

JobStoreType是一个枚举：表示quartz的存储方式：RAM 或者JDBC。

QuartzProperties配置类：从yml或者properties中读取配置信息。
