Is it possible to define annotation that is composed or inherited from other annotations?

[Jukka Siivonen]

For example I know I can have

@WithUserDetails(value = DEFAULT_TEST_USERNAME)
annotation class SpringContextTest

[Jukka Siivonen]

but I cannot use @SpringContextTest like this:

[diesieben07]

Those so-called meta annotations have to be explicitly supported by whatever framework / library is consuming those annotations

[Jukka Siivonen]

@SpringContextTest(username = "foo")

[diesieben07]

In the case of spring you can use @AliasFor(annotation = SpringContextTest) on your username property

[diesieben07]

Probably need @AliasFor(annotation = SpringContextTest::class, attribute = "value") acutally. Not quite sure how @SpringContextTest looks

[Jukka Siivonen]

to be precise my custom @SpringContextTest just wraps two Spring annotations

[Jukka Siivonen]

@SpringBootTest
@WithUserDetails(value = DEFAULT_TEST_USERNAME)
annotation class SpringContextTest

[Jukka Siivonen]

and I would like to have possibility to use my annotation in tests as @SpringContextTest(username = "foo") or just @SpringContextTest (default user)

I will look in to AliasFor, I did not know about that. Thanks
