Multiple datasources with same repositories and entities

问题

I have a current requirement of allowing multiple data sources for the same repositories/entities in spring boot using jpa.

What I've managed to find was always related to multiple datasources, with multiple repositories/entites.

However, here I would like to have the same repositories and entities (ie same database structure) for multiple datasources.

And based on same property, programmatically activate a specific datasource.

I've tried the setup demo'ed here: https://github.com/spring-projects/spring-data-examples/tree/master/jpa/multiple-datasources

And in both configurations use the same package in the factoryBean.setPackagesToScan() call. This does now work however, one datasource overrides the other.

My current test can be found here: https://github.com/nWidart/spring-data-multi-datasource/tree/master/src/main/java/com/example/multidatasources

It shows the 2 configuration files (client1 and client2) with a repository and entity. The controller has 2 endpoints for both data sources (not working).

Thanks!

回答1:

you can do like below :

1. application.properties (as default) : as you see, you can switch between datasource files.
2. application-test.properties (sample)
I hope this can help you. :D
