Java org.springframework.beans.factory.nouniquebeandDefinitionException：没有类型为'的合格bean；org.apache.ibatis.session.SqlSessionFactory'；

我知道在互联网上有很多关于同一问题的例子。但我想得到的是架构层面的帮助

我有一个简单的spring项目，其中我有一个配置类 （distDataSource，shipmentDataSource）。对于下面提到的两个数据源（MyBatisDISTDataSource，MyBatisShipmentDataSource），我有两个单独的类

这两个DataSorce分别工作得很好，但当我试图同时执行它时，控制台上出现异常

控制台异常日志
