Registering test bean with same name in Spring Framework 5.1












1














I'm having following config in my production files:



@Configuration
internal class Config {

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


In tests:



@Configuration
class ClockTestConfiguration {

@Bean
fun clock() = SetableClock()
}


My test annotations:



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


When I was using Spring Boot 2.0.5.RELEASE it worked like a charm. After upgrading to 2.1.0.RELEASE it fails during bean registration.



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);
defined in com.foo.clock.ClockTestConfiguration] for bean 'clock': There is already [Root bean: class [null]; scope=; abstract=false; lazyInit=false; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=config; factoryMethodName=clock; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [com/foo/clock/Config.class]] bound.
at org.springframework.beans.factory.support.DefaultListableBeanFactory.registerBeanDefinition(DefaultListableBeanFactory.java:894)


Is there a clean way to override such bean?

You could use the properties attribute of @SpringBootTest to set spring.main.allow-bean-definition-overriding=true.
