Description
spring boot version: 2.6.3
I have defined several annotations in kotlin similar to the following:
@JvmRepeatable(Bar::class)
annotation class Foo(val value: Bar = Bar())
annotation class Bar(vararg val value: Foo)This does not seem to be possible in Java, but kotlin allows it. Then I use it in springboot:
@RestController
class HappyController {
@Foo
@Foo
@GetMapping("/hi")
fun fine() = "Hello World"
}I get exceptions at startup:
