The same project can sometimes involve multiple databases, or multiple data sources. Multiple data sources can be divided into two situations:1) Two or more databases are not relevant, independent of each other, in fact, this can be developed as two projects. For example, in the game development of a database is a platform database, and other platforms under the game corresponding database;2) Two or more da

In our project, we encountered the problem of connecting multiple databases to our projects, and different clients accessing different databases as needed in each visit. We used to always configure a data source in the spring and hibernate frameworks, so the DataSource property of Sessionfactory always points to this data source and remains constant, All DAO uses this data source to access the database when Sessionfactory is used. But now, because of the needs of the project, our DAO in Access t

In general, it is possible to set a default data source to specify a new data source where the service needs to switch the data source, but there are two disadvantages: (1) Too many ways to specify new data sources
