ImportSelector:复杂bean的实现
Condition: true,false 条件注解
ImportBeanDedfinedRegister:手动将bean 放到ioc容器中
FactoryBean: getObject();getType(); isSington();将实例放入到容器中
BeanFactory: getBean(); 获取bean实例的工厂

InstantitionAwareBeanPostProcessor: bean 实例化前后的增强处理器
InitializingBean:设置属性值的后置处理七
BeanPostProcessor：对初始化进行增强

@PostStruct
@Desdory
