Say I have a class like this: ```@RestController class Foo(val bar: Bar, val baz: Baz = Baz("ding"))...

# spring

Say I have a class like this:

@RestController
class Foo(val bar: Bar, val baz: Baz = Baz("ding"))

bar and baz will be autowired automatically as expected. But is it possible to disable autowiring for baz since it has a default value?

[Ties]

Just out of interest, what is the usecase? In case spring does not have a Baz bean, use this default one instead? (within spring that would be solved with conditional bean loading)

[Ties]

and if you want it to be a property of the class but not being set by the constructor you can just create a separate property https://kotlinlang.org/docs/properties.html

[henrik]

it's convenient to have all dependencies in the constructor when testing Foo

[henrik]

And Baz is maybe not available for autowiring now, but someone might add it later, thus braking Foo (or introducing interesting side effects). This exact thing happened in a project here earlier.

[Ties]

So it is a non-bean dependency, and you want to change it during testing? (if that is the case I think I would consider making it a bean)

[Ties]

Or you can give it as an argument to functions who actually need to use Baz

Yup. I was trying to avoid making it a bean, but it seems to be the only viable option. I was hoping for a @DontAutowire annotation or something 🙂

Sounds like you might be able to achieve this with a testing only constructor and di constructor

[Jacob]

Ie the di constructor delegates to the testing constructor and passes in the default arg
