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

[Kopylenko, D. <dko...@ac...>]

If there is a big demand for such a "query" method I could add it to
BeanFactory or AbstractBeanFactory. What everybody thinks?

 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?
