解决SpringBoot使用Quartz无法注入Bean的问题

创建自定义JobFactory

@Component
public class JobFactory extends SpringBeanJobFactory implements ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {

        beanFactory = context.getAutowireCapableBeanFactory();
    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
        final Object job = super.createJobInstance(bundle);

        beanFactory.autowireBean(job);

        return job;
    }
}

创建QuartzConfig

@Configuration
public class QuartzConfig {

    @Autowired
    private JobFactory jobFactory;

    public QuartzConfig(JobFactory jobFactory){
        this.jobFactory = jobFactory;
    }

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean() throws IOException{
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        schedulerFactoryBean.setOverwriteExistingJobs(true);
        schedulerFactoryBean.setJobFactory(jobFactory);
        return schedulerFactoryBean;
    }

    @Bean(name = "scheduler")
    public Scheduler scheduler() throws IOException {
        return schedulerFactoryBean().getScheduler();
    }
}
