How can I switch databases in a Spring Boot application?
You can switch databases in a Spring Boot application by configuring the application.properties
or application.yml
file to point to the new database.
What if I want to switch between multiple databases dynamically?
You can achieve dynamic database switching by using a RoutingDataSource
that determines the current database based on your application's context.
Can you show me an example of how to implement a RoutingDataSource?
Sure! You can create a class that extends AbstractRoutingDataSource
and override the determineCurrentLookupKey
method to return the current database key.
Are there any specific dependencies I need to add for this?
Yes, make sure to include the necessary database drivers and Spring Data JPA dependencies in your pom.xml
or build.gradle
.
