The answered provided by @Daniel C. is correct. Small correction/observation from my side.

• @Primary is not required if you don't want to mark any datasource as default one, otherwise necessary.
• If you are defining any of the EntityManagerFactoryBean with @Bean name as entityManagerFactory then it's better to mark it @Primary to avoid conflict.
• @ConfigurationProperties("app.datasource.servers") can be marked at class level instead of defining at method level.
• Better to return HikariDataSource as datasource if you using Spring Boot 2.x or higher version as it has been changed.
• Make sure you define exact property for jdbc-url which is being used by HikariDataSource to refer JDBC Connection URL.
