Thanks Tomasz.Point1:- Does spring give runtime error in case of circular dependency? Point2:-Just trying to understand with example.Are you saying that if i have class A which is using Class B as dependency in its constructor(class B does not implement interface).Wont it be possible?

Think about it: if bean A requires an instance of bean B on startup and bean B requires an instance of bean A, there is no way to instantiate them. When Spring detects such a situation it throws an exception when starting. However with setter/field injection Spring can firdt create instances and then inject them, no problem in this situation.

If this is a common problem in your project, though, then you probably have other things to worry about than DI style.
