Spring container in web application - looking for beans.

[AdWeed]

Hello

I have one question about Spring way of finding and initializing beans.

In my web application that is deployed to Tomcat 7.0 most of the beans are annotated with @Component annotation, so we don't have so much xml code.

During the startup of Tomcat I can see a message:

INFO : org.springframework.beans.factory.support.DefaultListableBeanFactory - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1172fb9:

and there goes a long list of beans, like:

org.springframework.security.filterChains

and others from Spring, but among them I can see the names of the classes that I annotated with @Component.

After those information I am getting info about mapping methods to URLs.

As far as I understand Spring configuration, it knows where to look for beans because I put

<context:component-scan base-package="package.to.scan" />

in my .xml configuration file.

But if I remove this line from the configuration file I am still getting this line about DefaultListableBeanFactory and list of beans,

Interesting thing is, that if I don't remove

<context:component-scan base-package="pl.meble.taboret" />

I am getting

org.springframework.beans.factory.support.DefaultListableBeanFactory@1172fb9:

listed twice, like Spring is loading beans twice.

Apart from

<context:component-scan base-package="pl.meble.taboret" />

how is it possible to point packages for Spring container to scan for beans?

EDIT:
Sorry for all the fuss, it seems I had component-scan in two .xml files, so that is why beans were loaded twice.

Is logging output hitting your console twice perhaps?

Just a thought.

You could peak at the beans within your applicationContext.

Query the beanFactory within your applicationContext to see what is being loaded:

Assuming you have access to applicationContext you could do:
ctx.getBeanFactory().getBeanDefinitionCount() <== returns the number of beans defined in the factory.
ctx.getBeanFactory().getBeanDefinitionNames() <== return the names of all beans defined in this factory.
