Re: [Springframework-developer] how to determine if a bean exists in registry?

Message Although, I would still prefer a simpler method that just =
returns a boolean, but your solution will work for me.

Thanks!!!!

  Or better yet use AbstractBeanFactory.getBeanDefinition(String =
beanName) which would throw NoSuchBeanDefinitionException if bean does =
not exist.

    Rajeev,

    you could use String[] getAliases(String name) throws =
NoSuchBeanDefinitionException in BeanFactory and catch =
NoSuchBeanDefinitionException. If caught, then bean does not exist in =
the factory.

      Is there an easy way to determine if a certain bean exists in the =
beanFactory?  I know one can use the getBean(name) to determine that, =
but it seems an expensive call,  especially, if there are bean post =
processors associated with it.  Don't you think having a function like   =
 boolean containsBean(String beanName) in a beanFactory class would be =
useful here?
