Hello @Terrdi ,

If this is about switching the databaseId while the application is running, it may require major design change.

Could you explain the use case?
I am curious why people need this.

I hope to support multiple data sources (different interfaces access different types of databases) instead of just one type of database.

In that case, you should create multiple SqlSessionFactory instances (e.g. factory 1 for Oracle and factory 2 for MySQL) and add mappers used in each DB (e.g. add mapper A and B to factory 1; add mapper C, D and E to factory 2).
Search "mybatis multiple datasource" and you'll find many articles/examples.
