How to make spring quartz scheduler as the global variable

1. After creating a scheduler object from Scheduler Factory make it as global access.
2. So we can access scheduler from anywhere of our application.
3. By using @Bean we can create scheduler object at global level.

@Bean
private Scheduler getScheduler() {
	StdSchedulerFactory factory = new StdSchedulerFactory();
	try {
		factory.initialize(new ClassPathResource("quartz.properties").getInputStream());
		return factory.getScheduler();
	} catch (Exception e) {
		e.printStackTrace();
	}
	return null;
}

4. Access scheduler variable using @Autowired

@Autowired
private Scheduler scheduler;
