Kotlin 在 Spring Framework 5.1 中注册具有相同名称的测试 bean

我的生产文件中有以下配置:

@Configuration
internal class Config {

  @Bean
  fun clock() = Clock.systemUTC()
}

在测试中:

@Configuration
class ClockTestConfiguration {

  @Bean
  fun clock() = SetableClock()
}

My test annotations:

@SpringBootTest(
  webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
  classes = [
    MyApplication::class,
    ClockTestConfiguration::class
  ]
)
class MyTest {
...

当我使用Spring Boot2.0.5.RELEASE的时候，它的效果非常棒.升级到2.1.0.RELEASE后，在Bean注册期间失败.

Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'clock' defined in com.foo.clock.ClockTestConfiguration:

Is there a clean way to override such bean?
