InitializingBean不同于ServletContextListener，InitializingBean必须在service层才会启动执行，且可以使用注解的方式注入对象

@Service
public class OrderInitializingBean implements InitializingBean{

	public static OrderDelayQueueThread OrderDelayQueueThread = null;

	@Autowired
	private RedisTemplate redisTemplate;//可注入

	@SuppressWarnings("unchecked")
	@Override
	public void afterPropertiesSet() throws Exception {
		//做逻辑
		System.out.println("项目启动执行……");
	}
}
