I have been experimenting with using Spring 3.1's bean definition profiles and nested beans. I had hoped that I could define different beans depending on the active profile. Consider the following heavily over simplified example such that my Spring context contains something like
<bean id="say" class="test.Say" p:hello-ref="hello"/>
<beans profile="prod">
<bean id="hello" class="test.Hello" p:subject="Production!"/>
</beans>
<beans profile="dev">
<bean id="hello" class="test.Hello" p:subject="Development!"/>
</beans>
I get the following error:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'say' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'hello' while setting bean property 'hello'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'hello' is defined at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:328) at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveValueIfNecessary(BeanDefinitionValueResolver.java:106) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1360) aJava Result: 1
I was expecting that the hello bean would be defined according to the active Maven profile (in my case prod or dev). I'm starting to think that the Spring active profiles (spring.profiles.active) may be completely unrelated to Maven profiles.
Could somebody please explain where I am going wrong? (Is this even possible using profiles?).
