Spring bean声明中的ref vs idref属性 [英] ref vs idref attributes in spring bean declaration

问题描述

有人可以告诉我两者之间的区别吗

Can someone tell me the difference between

<bean id="b1" class="" />

<bean id="" class="">
 <property name="b1" ref="b1" />
</bean>

和

<bean id="" class="">
 <property name="b1" idref="b1" />
</bean>

什么时候需要使用哪一个?

and which one has to be used when?

推荐答案

ref用于传递引用所引用的bean.
idref用于传递所引用的bean的名称(作为String).

ref is used to pass the bean that the ref refers to.
idref is used to pass the name of the bean (as a String) that is referred to.
