This section answers questions that arise from using Spring Batch with Spring Boot.
NOTE: By default, batch applications require a `DataSource` to store job details.
Batch autowires a single `DataSource` in your context and
uses that for processing. If you like to use a different `DataSource`, you can create
one and mark it is `@Bean` as `@BatchDataSource`. If you do so and want two data sources,
remember to create another one and mark it as `@Primary`. If you want to deviate from that,
you need to implement `BatchConfigurer`. See
{spring-batch-javadoc}/core/configuration/annotation/EnableBatchProcessing.html[The
Batch autowires a single `DataSource` in your context and uses that for processing. To
have Batch use a `DataSource` other than the application’s main `DataSource`, declare a
`DataSource` bean, annotating its `@Bean` method with `@BatchDataSource`. If you do so and
want two data sources, remember to create another one and mark it as `@Primary`. To take
greater control, implement `BatchConfigurer`. See
{spring-batch-javadoc}/core/configuration/annotation/EnableBatchProcessing.html[the
Javadoc of `@EnableBatchProcessing`] for more details.
