jpaAuditingRegistrar中的SpringBean重写throws错误

spring-data-jpa spring-boot spring java

默认情况下,不再允许切换到SpringBoot2.1.0.ReleaseBean覆盖。这会导致以下错误:

...

通过一些调试,我发现 org.springframework.data.jpa.repository.config.JpaAuditingRegistrar.registerBeanConfigurerAspectIfNecessary(BeanDefinitionRegistry) 将被呼叫两次。如果有人能解释这个btw就好了。无论如何,该方法中的第一个if语句应该能够识别类型为bean的 AnnotationBeanConfigurerAspect 已经注册,并且不导致重写异常:

private void registerBeanConfigurerAspectIfNecessary(BeanDefinitionRegistry registry) {

    if (registry.containsBeanDefinition(BEAN_CONFIGURER_ASPECT_CLASS_NAME)) {
        return;
    }

registry.containsBeanDefinition 检查 key 在里面 registry.definitionMap 对于 org.springframework.beans.factory.aspectj.AnnotationBeanConfigurerAspect . 但是 BeanDefinition 如下所示:

key = org.springframework.context.config.internalBeanConfigurerAspect
value = Bean of Type [org.springframework.beans.factory.aspectj.AnnotationBeanConfigurerAspect]

似乎 钥匙 和 value 混在一起了。

故障是由 bug 在春季数据JPA中, has been fixed 但尚未发布。它是Spring Data Lovelace SR3的一部分,将包含在Spring Boot 2.1.1中。
