import org.springframework.stereotype.Component;



@Component
public class SpringUtil implements ApplicationContextAware {

	public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
		SpringUtil.applicationContext = applicationContext;
	}

	public static ApplicationContext getApplicationContext() {
		return applicationContext;
	}

	/**

	 * 
	 * @return bean实例
	 * 
	 * @throws BeansException
