what exactly does the @with annotation do? (Play Framework)

Question

I don\'t quite understand what the @with annotation does.

in the Play framework site, it is written :

we can annotate the controllers using t

Answer 1

Suppose you have 2 controllers:

• A has @Before or other controller action injection annotations,
• B get annotated with @With(A.class)

All those injection actions defined in A will be effective when calling B's action methods.

It's kind of inheritance. However with inheritance you can extend at most one class. But you can do @With({A.class, Z.class, ...})
