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. Currently, there are about two ways to build Spring multiple data sources that I know of, and you can choose according to the situation of multiple data sources. 1. Use the spring configuration file to directly configure multiple data sources. For example, if the two databases are not related, you can directly configure multiple data sources in the spring configuration file, and then configure the transactions separately, as shown below: < ;context:component-scan base-package="net.aazj.ser
