Spring Boot 2.3.1重复的Bean定义

Question

我正在从Spring Boot 1.5. x升级到2.3.1。

遇到以下错误，已在Spring boot中修复。https://jira.spring.io/browse/DATAJPA-1448

尝试了以下属性解决方法，但效果不佳。

Spring主要的允许bean定义重写=true

有人面临同样的问题或解决方法吗？

以下错误

org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'org.springframework.context.config.internalBeanConfigurerAspect' defined in org.springframework.context.annotation.aspectj.SpringConfiguredConfiguration: Cannot register bean definition [Root bean: class [null]; scope=; abstract=false; lazyInit=null; autowireMode=3; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=org.springframework.context.annotation.aspectj.SpringConfiguredConfiguration; factoryMethodName=beanConfigurerAspect; initMethodName=null; destroyMethodName=(inferred); defined in org.springframework.context.annotation.aspectj.SpringConfiguredConfiguration] for bean 'org.springframework.context.config.internalBeanConfigurerAspect': There is already [Root bean: class [org.springframework.beans.factory.aspectj.AnnotationBeanConfigurerAspect]; scope=; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=aspectOf; initMethodName=null; destroyMethodName=null] bound.

更新

**

以编程方式设置AllowBean定义覆盖有助于解决这部分问题（之前尝试通过属性文件注入），但保持此线程打开，因为原始根原因在sping-jpa中，sping-bean还不明显。

   SpringApplication sa = new SpringApplication(xxxxxxx.class);
   sa.setAllowBeanDefinitionOverriding(true);

Answer 1

我们面临着与OP类似的问题——一旦从Spring boot2.2.8升级到2.3.1，围绕自动配置的jUnit测试开始失败，出现BeanDefitionOverrideException错误，OP提到的解决方案不起作用。通过属性文件或环境后处理器设置属性spring.main.allow-bean-定义-覆盖=true也不起作用。

修复：

我们正在使用Application ationContextRunner来测试在上下文中加载多个bean。从Application ationContextRunner的实例中调用带有AllowBeanDefitionOverger（true）的方法修复了它。

根据此处的Spring Boot 2.3.0发行说明

“为了与SpringApplication保持一致，ApplicationContextRunner现在默认情况下禁用bean重写。如果需要对测试使用bean重写，可以使用withAllowBeanDefinitionOverriding来启用它。”
