Spring annotation scan optimization

Question

I using annotation configuration for spring context like

<context:annotation-config/>
<context:component-scan base-package="example"/>

But project is fairly large and scanning for both components have much time (10 s for one scan). Can I configure this in only one scan, that is proceeded in ?

I think the base-package value can actually contain multiple packages. Try specifying something like:

<context:component-scan base-package="example.package.one,example.package.two"/>

Where you are explicitly specifying only the packages you need.

10s is not much time at all, because it is performed only once - on startup. You can limit the scanned packages by specifying more detailed package names (not just example).

You mention "both" - if you have only 2 spring beans, just list them with <bean> in the XML and drop the component scan.

10s it's time of one scaning, it's fairly large and grow up with project evolution

@user298061 how many spring beans do you have? Are you sure it is only for scanning, or for initialization of all the beans?

They are several hundred, but 10 s it's scaning only excluding bean registation
