具有多个数据源的存储库Bean创建错误

Question

我遇到的情况是我必须在应用程序中处理两个不同的数据源。我需要观察基于xml的配置，否则有大量的解决方案可以在线进行类级配置。

以下是我的配置：

我必须在配置中做或丢失一些东西。当我执行我的应用程序时，它返回异常：

我还试图在组件扫描下给出存储库路径，但是没有用。

Answer 1

我通过在 spring-jpa.xml

中添加以下行来解决了这个问题

<jpa:repositories base-package="com.soft.paramount.repository.mdm" entity-manager-factory-ref="entityManagerFactoryMdm"/>
    <jpa:repositories base-package="com.soft.paramount.repository.product" entity-manager-factory-ref="entityManagerFactoryProduct"/>
