BeanDefinitionOverrideException，但启用了Spring属性重写

Question

尽管在主application.yml中启用了spring-property allow-bean-definition-overriding: true，但我还是得到了一个异常。有什么线索吗？

Answer 1

如果您查看错误消息，它会显示：

考虑重命名其中一个beans或通过设置spring.main.allow-bean-definition-overriding=true.启用覆盖

确保allow-bean-definition-overriding属性位于spring.main元素之下。
