SpringIoc容器对象获取工具，解决反射出来的对象的属性注入为空的问题。

(此工具可以通过类名或者class从spring容器中获取对象实例)有效的解决了反射出来的对象里面的注入的对象为空的问题

@Slf4j
@Component
public class GetBeanUtil implements ApplicationContextAware {protected static ApplicationContext context;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {if(GetBeanUtil.context == null) {GetBeanUtil.context = applicationContext;}log.info("========ApplicationContext配置成功,在普通类可以通过调用SpringUtils.getAppContext()获取applicationContext对象");}//获取applicationContextpublic static ApplicationContext getApplicationContext() {return context;}//通过name获取 Beanpublic static Object getBean(String name) {//name表示其他要注入的注解name名return context.getBean(name);}//通过class获取Beanpublic static <T> T getBean(Class<T> clazz){return getApplicationContext().getBean(clazz);}//通过name,以及Clazz返回指定的Beanpublic static <T> T getBean(String name,Class<T> clazz){return getApplicationContext().getBean(name, clazz);}}

用法：

 Class cals = Class.forName("全类名ClassName");RenewRateObserver obj = (RenewRateObserver)GetBeanUtil.getBean(cals);
