= Multiple DataSources Sample Task This is a Spring Boot application that utilizes two DataSources and explicitly configures which one to be used for the Spring Cloud Task repository. == Requirements: * Java 17 or Above == Classes: * `MultipleDataSourcesApplication` - the Spring Boot Main Application. * `SampleCommandLineRunner` - the `CommandLineRunner` implementation for this task. It outputs the number of `DataSource` beans found in the context (should be 2). * `EmbeddedDataSourceConfiguration` - Configures two `DataSource` beans using embedded databases. * `ExternalDataSourceConfiguration` - Configures two `DataSource` beans using external databases. * `CustomTaskConfigurer` - Uses a Spring `@Qualifier` to specify the correct `DataSource` to use. == Build: [source,shell,indent=2] ---- $ mvn clean package ---- == Execute sample using 2 embedded databases (default): [source,shell,indent=2] ---- $ java -jar target/multiple-datasources-3.0.0.jar ---- == Execute sample using 2 external databases: Using the `external` profile, users will be able to establish both the default `spring.datasource` data source and a `second.datasource` data source. For example: [source,shell,indent=2] ---- export spring_datasource_url=<your db url> export spring_datasource_username=<your db user name> export spring_datasource_password=<your db user password> export spring_datasource_driverClassName=org.mariadb.jdbc.Driver export second_datasource_url=jdbc:<your db url> export second_datasource_username=<your db user name> export second_datasource_password=<your db user password> export second_datasource_driverClassName=org.mariadb.jdbc.Driver java -jar target/multiple-datasources-2.3.0-RELEASE.jar --spring.profiles.active=external ----
