springBoot + orcal + mybatisPlus + multi data source

Projects to use multiple data sources so learning a little, himself read many articles and finally succeeded, where the main part of the recording for later review (pom-dependent files are not posted).
A. Profile application.yml which add a data source
note shrink and into the spaces must be careful

II. Dao two databases mapper layer and the layer to be placed in their respective designated folder which facilitates data source

III. Create Entity each type of data source configured for injecting into the spring

A data source entity classes: DefaultDataSourceConfig.java
