What is the method for configuring multiple data sources in MyBatis?

There are two methods supported by MyBatis for configuring multiple data sources: using multiple SqlSessionFactory and using multiple SqlSessionTemplate.

1. Utilizing multiple SqlSessionFactory instances:
2. Initially, configure the connection information of multiple data sources in the application.properties or application.yml file.
3. Next, create multiple DataSource objects and configure them as Spring beans.
4. Next, create multiple SqlSessionFactory objects, each using different data sources and MyBatis configuration files.
5. Finally, create multiple Mapper interfaces and inject them into different SqlSessionFactory instances.
6. Utilize multiple SqlSessionTemplates.
7. First, configure the connection information for multiple data sources in the application.properties or application.yml file.
8. Next, create multiple DataSource objects and configure them as Spring Beans.
9. Next, create multiple SqlSessionFactory objects, each using a different data source and MyBatis configuration file.
10. Next, create multiple SqlSessionTemplate objects using multiple SqlSessionFactory instances, and configure them as Spring beans, specifying the corresponding SqlSessionFactory for each.
11. Finally, create multiple Mapper interfaces and inject them into different SqlSessionTemplates accordingly.

It is important to note that when using multiple data sources, you need to explicitly specify which data source to use in the code. This can be done by using the @Qualifier annotation on the Mapper interface methods or by configuring with db:annotation-driven in the configuration file.
