前提：

public class DataProviderManagerImpl implements ApplicationContextAware@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {this.applicationContext = applicationContext;}

　　

强行注入：

//允许bean实例在所有的bean属性被设置时才能执行

if (provider instanceof InitializingBean) {((InitializingBean) provider).afterPropertiesSet();}applicationContext.getAutowireCapableBeanFactory().autowireBean(provider);

　　

强行引用: --就是普通的GetBean

InnerAggregator innerAggregator = applicationContext.getBean(H2Aggregator.class);
