Spring启动集成测试-BeanDefinitionOverrideeException

Question

我有一个Spring Boot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：

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);
    }
}

properties-context.xml定义如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:util="http://www.springframework.org/schema/util"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                            http://www.springframework.org/schema/beans/spring-beans.xsd
                            http://www.springframework.org/schema/context
                            http://www.springframework.org/schema/context/spring-context.xsd
                            http://www.springframework.org/schema/util
                            http://www.springframework.org/schema/util/spring-util.xsd">

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


</beans>

这从一个名为external.properties.的文件中读取，在我的外部属性文件中设置了属性'spring.main.allow-Bean-定义-覆盖=true'。我添加此项是因为当我运行应用程序时，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集成测试中？

Answer 1

嗯，考虑到您的错误，这似乎是合乎逻辑的：当Spring创建一个与已经创建的bean同名的bean时，org.springframework.beans.factory.support.BeanDefitionOverrideExc0019被抛出。属性spring.main.allow-bean-定义-覆盖=true，在Spring Boot2中默认关闭，是为了允许bean覆盖。

我不明白为什么你有两个豆子和同样的关于交易...
