spring boot 集成quartz-job如何自动注入spring容器托管之后怎么动态开启定时器停

Answer 1

我们通过实现JobFactory 接口，在实例化Job以后，在通过ApplicationContext 将Job所需要的属性注入即可
在Spring与Quartz集成时 用到的是org.springframework.scheduling.quartz.SchedulerFactoryBean这个类。源码如下，我们只看最关键的地方。
// Get Scheduler instance from SchedulerFactory. try {
this.scheduler = createScheduler(schedulerFactory, this.schedulerName);
populateSchedulerContext();

if (!this.jobFactorySet && !(this.scheduler instanceof RemoteScheduler)) {
// Use AdaptableJobFactory as default for a local Scheduler, unless when // explicitly given a null value through the "jobFactory" bean property. this.jobFactory = new AdaptableJobFactory(); }
if (this.jobFactory != null) {
if (this.jobFactory instanceof SchedulerContextAware) {
((SchedulerContextAware) this.jobFactory).setSchedulerContext(this.scheduler.getContext());
}
this.scheduler.setJobFactory(this.jobFactory);
}
}
