Spring dependency injection controll

Question

How do I control/restrict the instantiation of bean?

Lets say, I have 2 beans

1. A.java
2. B.java

Scopes of the both the bean as singleton & configured inside Spring application context

If A bean gets instantiated then B shouldn't vice-versa if B gets instantiated the A shouldn't.

Answer 1

You can use @Conditional or @Profile. For first annotation you can write a class which will check if your bean exists.
