oop - Favour composition over inheritance - always?

Question

Should composition be favoured over inheritance as rule - in all circumstances?

I have read that inheritance is actually now being seen as an anti pattern. My problem with that is that some relationships logically fit into inheritance i.e. is-a relationships.

But from reading lately this is seen as wrong?

What is the way to go with this?

不，在所有情况下，组合都不应该优先于继承。您通常将它们用于不同的事情和不同的情况。
