Spring Boot application integrates multiple DataSource quickly.

Quickstart

        primary:
            url: 'jdbc:mysql://127.0.0.1:3306/test_db1'
            driver-class-name: com.mysql.cj.jdbc.Driver
            type: com.zaxxer.hikari.HikariDataSource
            jpa-enabled: true
            repository-enabled: true
            mybatis:
