Spring boot Spring启动集成测试-BeanDefinitionOverrideeException

我有一个Spring引导集成测试，其类定义如下

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {TestApplication.class})
@Transactional
public class AuthorisationManagerControllerRequestIT
{
...

我得到以下例外情况：

Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'org.springframework.transaction.config.internalTransactionAdvisor' defined in class path resource [org/springframework/transaction/annotation/ProxyTransactionManagementConfiguration.class]: Cannot register bean definition [Root bean: class [null]; scope=; abstract=false; lazyInit=null; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration; factoryMethodName=transactionAdvisor; initMethodName=null; destroyMethodName=(inferred); defined in class path resource [org/springframework/transaction/annotation/ProxyTransactionManagementConfiguration.class]] for bean 'org.springframework.transaction.config.internalTransactionAdvisor': There is already [Root bean: class [org.springframework.transaction.interceptor.BeanFactoryTransactionAttributeSourceAdvisor]; scope=; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] bound.

我的TestApplication类定义如下：

@SpringBootApplication
@ComponentScan(excludeFilters = {
        @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = Application.class)
})
@ImportResource({
        "classpath:properties-context.xml"          
})
public class TestApplication
{
    public static void main(String[] args)
    {
        SpringApplication.run(TestApplication.class, args);
    }
}

    <context:property-placeholder location="${CONFIG.ROOT}/external.properties"/>


</beans>

它读取properties-context.xml，其定义如下：

@SpringBootApplication
@ComponentScan(excludeFilters = {
        @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = Application.class)
})
@ImportResource({
        "classpath:properties-context.xml"          
})
public class TestApplication
{
    public static void main(String[] args)
    {
        SpringApplication.run(TestApplication.class, args);
    }
}

       xsi:schemaLocation="http://www.springframework.org/schema/beans

                            http://www.springframework.org/schema/util
                            http://www.springframework.org/schema/util/spring-util.xsd">

    <context:property-placeholder location="${CONFIG.ROOT}/external.properties"/>


</beans>

这将读取名为external.properties的文件。我在外部属性文件中设置了属性“spring.main.allow bean definition overriding=true”。我之所以添加此项，是因为我在运行应用程序时，出现了相同的异常，但添加此项后不再出现

需要什么来阻止此异常出现在我的集成测试中？

考虑到您的错误，这似乎是合乎逻辑的：

org.springframework.beans.factory.support.BeanDefinitionOverrideeException

在spring创建与已创建的bean同名的bean时抛出。属性

spring.main.allow bean definition overriding=true

，在spring boot 2的默认情况下被关闭，用于允许bean重写

我不明白的是为什么你有两个关于事务的bean是相同的
