java - 如何在 Spring 5 中使用自定义 'TransactionAttributeSource'

Question

在 Spring 5 中，有ProxyTransactionManagementConfiguration。

这定义了:

@Bean
@Role(BeanDefinition.ROLE_INFRASTRUCTURE)
public TransactionAttributeSource transactionAttributeSource() {
    return new AnnotationTransactionAttributeSource();
}

当我在自己的配置中定义自己的 TransactionAttributeSource 时，例如:

@Bean
@Primary
public TransactionAttributeSource transactionAttributeSource() {
    return new RollbackOnAllTransactionAttributeSource();
}

我收到错误:

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

如何在 Spring 5 中使用自定义“TransactionAttributeSource”。 (它适用于 Spring 4。)

有什么想法吗？ TIA!

解决办法是设置

spring.main.allow-bean-definition-overriding=true

我在这里找到它:Spring Boot Upgrade Error - Invalid bean definition with name org.springframework.transaction.config.internalTransactionalEventListenerFactory
