在实际框架或产品开发过程中，springboot中集成quarzt方式基本是以job和trigger的bean对象方式直接硬编码完成的，例如以下代码示例。对于系统内定义的所有定时任务类型，具体执行类，执行策略，运行状态都没有一个动态全局的管理，所有决定将quartz做成可视化配置管理，便于统一管理，也降低了使用门槛，只需要关心job类的实现即可
@Bean
public JobDetail SMSJobDetail() {
return JobBuilder.newJob(SMSJob.class).withIdentity("SMSJob").storeDurably().build();
}
// 把jobDetail注册到trigger上去
@Bean
public Trigger myJobTrigger() {
SimpleScheduleBuilder scheduleBuilder = SimpleScheduleBuilder.simpleSchedule()
.withIntervalInSeconds(1).repeatForever();
return TriggerBuilder.newTrigger()
.forJob(SMSJobDetail())
.withIdentity("myJobTrigger")
.withSchedule(scheduleBuilder)
.build();
}用于存储quartz配置

}支持Job类注bean入对象
@Component
public class QuartzFactory extends AdaptableJobFactory {
@Autowired
private AutowireCapableBeanFactory capableBeanFactory;
@Override
protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
// 调用父类的方法
Object jobInstance = super.createJobInstance(bundle);
// 进行注入
capableBeanFactory.autowireBean(jobInstance);
return jobInstance;
}
}注入QuartzFactory对象
@Configuration
public class QuartzConfig {
@Autowired
private QuartzFactory quartzFactory;
@Bean
public SchedulerFactoryBean schedulerFactoryBean(){
SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
schedulerFactoryBean.setJobFactory(quartzFactory);
//将job实例化，能够操作进行Spring 注入
return schedulerFactoryBean;
}
}定时任务动态添加/删除操作类，initQuartzTask方法在系统启动时执行，根据配置自动开启相关符合条件的任务
@Component
public class QuartzUtil {
@Autowired
private SchedulerFactoryBean schedulerFactoryBean;
@Autowired
private F_QuartzTaskService quartzTaskService;

public void initQuartzTask() {

if(openTaskList.size()>0){
openTaskList = openTaskList.stream().filter(a -> a.getTaskStatus() == QuartzEnum.TaskStatus.Open.get_value() &&
(a.getEnviroment().equals(QuartzEnum.TaskEnviroment.All.get_name()) || a.getEnviroment().equals(active))).collect(Collectors.toList());
}
for (F_QuartzTaskDO taskDO : openTaskList) {
try {
Class<Job> jobClass = (Class<Job>) Class.forName(taskDO.getJobClassPath());
if (taskDO.getTaskType() == QuartzEnum.TaskType.Cycle.get_value()) {
addIntervalJob(taskDO.getTaskTag(), jobClass, taskDO.getExecutePeroid(), taskDO.getExecuteUnit());
} else {
addCornJob(taskDO.getTaskTag(), jobClass, taskDO.getCornExpress());
}
} catch (Exception e) {
e.printStackTrace();
}
}
if (openTaskList.size() > 0) {
System.out.println("扫描并初始化开启quartz定时任务成功，任务数量：" + openTaskList.size() + "个");
}
}
public void startTask( F_QuartzTaskDO taskDO){
try {
Class<Job> jobClass = (Class<Job>) Class.forName(taskDO.getJobClassPath());

} else {
addCornJob(taskDO.getTaskTag(), jobClass, taskDO.getCornExpress());
}
} catch (Exception e) {
e.printStackTrace();
}
}
//增加定时任务任务
public void addIntervalJob(String jobName, Class<? extends Job> cls, int peroid, int timeUnit) {
try {
SimpleScheduleBuilder scheduleBuilder = null;
if (timeUnit == QuartzEnum.ExecuteUnit.Second.get_value()) {
scheduleBuilder = SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(peroid).repeatForever();
} else if (timeUnit == QuartzEnum.ExecuteUnit.Minute.get_value()) {

} else if (timeUnit == QuartzEnum.ExecuteUnit.Hour.get_value()) {
scheduleBuilder = SimpleScheduleBuilder.simpleSchedule().withIntervalInHours(peroid).repeatForever();
}
Scheduler sched = schedulerFactoryBean.getScheduler();
JobDetail jobDetail = JobBuilder.newJob(cls).withIdentity(jobName, JOB_GROUP_NAME).storeDurably().build();
Trigger trigger = TriggerBuilder.newTrigger().forJob(jobDetail).withIdentity(jobName, TRIGGER_GROUP_NAME).withSchedule(scheduleBuilder).build();
sched.scheduleJob(jobDetail, trigger);
if (!sched.isShutdown()) {
sched.start(); // 启动
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}
//增加corn表达式任务
public void addCornJob(String jobName, Class<? extends Job> cls, String cornExpress) {
try {
Scheduler sched = schedulerFactoryBean.getScheduler();
JobDetail jobDetail = JobBuilder.newJob(cls).withIdentity(jobName, JOB_GROUP_NAME).build();
CronTrigger trigger = (CronTrigger) TriggerBuilder
.newTrigger()
.withIdentity(jobName, TRIGGER_GROUP_NAME)

.build();
sched.scheduleJob(jobDetail, trigger);

} catch (Exception e) {
throw new RuntimeException(e);
}
}
//停止任务
public void deleteJob(String jobName) {
try {

TriggerKey triggerKey = TriggerKey.triggerKey(jobName, TRIGGER_GROUP_NAME);
JobKey jobKey = JobKey.jobKey(jobName, JOB_GROUP_NAME);
sched.pauseTrigger(triggerKey); // 停止触发器
sched.unscheduleJob(triggerKey);// 移除触发器
sched.deleteJob(jobKey); // 删除任务
} catch (Exception e) {
throw new RuntimeException(e);
