[Springframework-developer] property placeholder in nested bean definitions

[Ou, R. <Ro...@sa...>]

Hi all,

I am not sure if this is a "feature" or a bug, but here it is.

I am trying to use property placeholders in my bean definition. I also =
happen to have some nested bean definitions. But it seems the property =
placeholders only work on top level bean definitions, not inside the =
nested ones.

So this works:

<beans>
  <bean class=3D"com.foo.A">
    <property name=3D"b">
      <ref bean=3D"b"/>
    </property>
  </bean>
  <bean id=3D"b" class=3D"com.foo.B">
    <property name=3D"xyz">
      <value>${xyz.value}</value>
    </property>
  </bean>
</beans>

But this doesn't:

<beans>
  <bean class=3D"com.foo.A">
    <property name=3D"b">
      <bean id=3D"b" class=3D"com.foo.B">
        <property name=3D"xyz">
          <value>${xyz.value}</value>
        </property>
      </bean>
    </property>
  </bean>
</beans>

Is this a bug?

Thanks,

Rong
