How Spring manages beans inside?

[Himanshu Gupta]

It was asked to me in an interview.

Can anyone help me in finding its answer.

[Nathan Pruett]

The base container interface is BeanFactory... but that's a really broad question...

[Himanshu Gupta]

Thanks Nathan.


Looking for more replies.

Spring internals could fill a small book. What specific type of information are you looking for?

Have you looked at the source code and are having a problem with a specific area?

[Himanshu Gupta]

I am looking for the design they are using to maintain the information about beans and the process how they create it? How the beans are maintained inside? What type of data structure they use?

I havn't looked at the source code. I want to know all this just to be aware that what happens inside.

Thanks David for the reply.

How about HashMaps.

Yep the BeanFactory is just a set of glorified HashMaps. So is Hibernate's SessionFactory.

Yes, there is a bit more to it than just that, but in terms of storage, that is what it uses.

Hashmaps with an occasional proxy tossed in for fun - that's all it is.

The rest is smoke and mirrors (sometimes fire depending upon your app).
