Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a single bean, but 2 were found:
        - bookDataSource: defined by method 'bookDataSource' in class path resource [li/koly/BookDbConfiguration.class]
        - userDataSource: defined by method 'userDataSource' in class path resource [li/koly/UserDbConfiguration.class]

When Spring use auto configuration, it needs to configure the HibernateJpaAutoConfiguration, which needs a single bean of DataSource. How you solve this problem?

Does your example ensure that any transaction can't span over both datasource's.
I need this approach for a monolith to spring boot microservice migration.

Hi,

When I used this sample with mysql having hibernate property generateddl as true then it created the tables into both schemas/databases. How to fix the same.
