MyBatis-Plus 关于mybatisplus多数据源问题

当前使用版本(必填,否则不予处理)

3.0.5版本

该问题是如何引起的？(确定最新版也有问题再提!!!)

https://mp.baomidou.com/guide/dynamic-datasource.html 配置了注解方式的多数据源，然后在service中我需要查询多个数据源的数据，查询方法不加事务注解，会出现will not be managed by Spring。加了事务注解的话，会出现数据源无法切换，会统一以默认的primary的数据源去查询所有的库，多数据源切换不生效.....

重现步骤(如果有就写完整)

service(){ aMapper.aa(); bMapper.bb(); }

@DS("A") AMapper

@DS("B") BMapper

报错信息

不加事务注解报的是 was not registered for synchronization because synchronization is not active will not be managed by Spring

加事务注解的是 org.springframework.jdbc.BadSqlGrammarException:

Error querying database. Cause: java.sql.SQLSyntaxErrorException: Table 'online.xxxxx' doesn't exist

The error may exist in cn/xx/mapper/XxxxMapper.java (best guess)

The error may involve defaultParameterMap

The error occurred while setting parameters

是要用这种方式来操作多数据源吗，之前官网的注解方式不推荐是吗 https://mp.baomidou.com/guide/dynamic-datasource.html
