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

jobStore:

#数据库方式

#初始化表结构

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。
