Spring:FactoryBeanNotInitializedException

配个bean，碰到个奇怪的问题：

引用

Caused by: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'orderService': org.springframework.beans.factory.FactoryBeanNotInitializedException: FactoryBean is not fully initialized yet
at org.springframework.beans.factory.support.AbstractBeanFactory$3.run(AbstractBeanFactory.java:1307)

why？原来是因为配的这两个bean相互引用了；相互引用就会报FactoryBeanNotInitializedException：

引用

If this FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding FactoryBeanNotInitializedException .
