Spring环境下非注入类获取注入类的对象

继承ApplicationContextAware实现工具类：

@Component
public class SpringContextUtil implements ApplicationContextAware
{private static ApplicationContext applicationContext = null;@Overridepublic void setApplicationContext(ApplicationContext context)throws BeansException{if (applicationContext == null){applicationContext = context;}}public static ApplicationContext getApplicationContext(){return applicationContext;}public static <T> T getBean(Class<T> clazz){return getApplicationContext().getBean(clazz);}public static final Object getBean(String beanName){return getApplicationContext().getBean(beanName);}
}
