@@ -438,6 +438,27 @@ created in addition to a number of beans made available to be autowired:
The core interface for this configuration is the `BatchConfigurer`. The default
implementation provides the beans mentioned above and requires a `DataSource` as a bean
within the context to be provided. This data source is used by the JobRepository.
You can customize any of these beans
by creating a custom implementation of the `BatchConfigurer` interface.
Typically, extending the `DefaultBatchConfigurer` (which is provided if a
`BatchConfigurer` is not found) and overriding the required getter is sufficient.
However, implementing your own from scratch may be required. The following
example shows how to provide a custom transaction manager:
====
[source, java]
----
@Bean
public BatchConfigurer batchConfigurer() {
return new DefaultBatchConfigurer() {
@Override
public PlatformTransactionManager getTransactionManager() {
return new MyTransactionManager();
}
};
}
