spring - should every class in my project be a bean?

问题

In my project there are several @repositories , @Services, @Controllers

My question is for the other 99% of the classes:

Should i declare them as beans as well?

pros\cons?

thanks..

Beans are a way of wiring together the larger components of an application. Not every object or class is a large component. Consider the String class, for example. So the answer is no.
