我正在尝试：

@SpringBootTest(
  webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
)

@EnableAutoConfiguration(
  exclude = [
    ReactiveOAuth2ClientAutoConfiguration::class,
    ReactiveOAuth2ResourceServerAutoConfiguration::class,
  ]
)
@ActiveProfiles("testcontainers")
internal class RecordIntegrationTest {
  @Test
  fun contextLoads() {}
}

与 testcontainers application.yml中的配置文件：

spring:
  config.activate.on-profile: testcontainers
  r2dbc.url: r2dbc:tc:postgresql:///databasename?TC_IMAGE_TAG=13.2
  flyway:
    enabled: false

但是它尝试两次创建存储库（可能还有其他bean）：

java.lang.IllegalStateException: Failed to load ApplicationContext
...
Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'recordRepository' defined in com.example.RecordRepository defined in @EnableR2dbcRepositories declared on R2dbcRepositoriesAutoConfigureRegistrar.EnableR2dbcRepositoriesConfiguration: Cannot register bean definition [Root bean: class [org.springframework.data.r2dbc.repository.support.R2dbcRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in com.example.RecordRepository defined in @EnableR2dbcRepositories declared on R2dbcRepositoriesAutoConfigureRegistrar.EnableR2dbcRepositoriesConfiguration] for bean 'recordRepository': There is already [Root bean: class [org.springframework.data.r2dbc.repository.support.R2dbcRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null; defined in com.example.RecordRepository defined in @EnableR2dbcRepositories declared on R2dbcRepositoriesAutoConfigureRegistrar.EnableR2dbcRepositoriesConfiguration] bound.

更新
当我将测试移到根包时发现它运行良好

src/test/kotlin/com/example/backend

但是当我把它放进包裹里的时候它就失败了

`src/test/kotlin/com/example/backend/subfolder`

更新2
我发现如果 src/main/kotlin 与出现异常的集成测试在同一个包中。
例如。：

data class X(@Id id: Long? = null)

// src/main/kotlin/com/example/x/XRepository.kt
interface XRepository : CoroutineCrudRepository<X, Long> {}

此测试失败，出现上述异常：

// src/test/kotlin/com/example/x/XIntegrationTest.kt
@SpringBootTest(classes = [BackendApplication::class])
@EnableAutoConfiguration(
  exclude = [
    ReactiveOAuth2ClientAutoConfiguration::class,
    ReactiveOAuth2ResourceServerAutoConfiguration::class,
  ]
)
@ActiveProfiles("testcontainers")
internal class XIntegrationTest {

  @Test
  fun contextLoads() {
  }
}

删除存储库或将集成测试移到另一个包可以正常工作。
