...but when I use it in the Spring tests like:

@SpringWebMockMvcTest
@RunWith(SpringRunner::class)
//@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
class PersonRouterTest {
  private lateinit var client: WebTestClient

  @LocalServerPort
  private var port: Int? = null

It says: this annotation is not applicable to target 'class'
