Recommended 10 multi-data source code (collection)

The same project sometimes involves multiple databases, that is, multiple data sources. Multiple data sources can be divided into two situations: 1) Two or more databases are not related and are independent. In fact, this can be developed as two projects. For example, in game development, one database is a platform database, and the other databases are corresponding to games under the platform; 2) Two or more databases are in a master-slave relationship. For example, mysql builds a master-master, and then brings There are multiple slaves; or master-slave replication built with MHA.

All DAOs access the database through this data source when using sessionFactory. But now, due to the needs of the project, our DAO. When accessing sessionFactory, I have to constantly switch between multiple data sources. The problem arises: how to make ses
