在Spring Framework 5.1中注册具有相同名称的测试bean

Question

我在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()
}

我的测试注释:

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

当我使用Spring Boot时,2.0.5.RELEASE它就像一个魅力.2.1.0.RELEASE在bean注册期间升级到它失败.

Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'clock' defined in com.foo.clock.ClockTestConfiguration: 
Cannot register bean definition [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=clockTestConfiguration; factoryMethodName=clock; initMethodName=null; destroyMethodName=(inferred);

是否有一种干净的方式来覆盖这样的bean？

您可以使用要设置的properties属性.@SpringBootTestspring.main.allow-bean-definition-overriding=true
