I'm testing Spring Batch using Spring boot. My need is to define jobs working on an Oracle Database but I don't want to save jobs and steps states inside this DB.
I've read in the documentation I can use a in-memory repository with the MapJobRepositoryFactoryBean.
Then, I've implemented this bean:
@Bean
public JobRepository jobRepository() {
MapJobRepositoryFactoryBean factoryBean = new MapJobRepositoryFactoryBean(new ResourcelessTransactionManager());
try {
JobRepository jobRepository = factoryBean.getObject();
return jobRepository;
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
But when my job starts, the first thing Spring Batch does is to create the table in the Oracle DB and continues to use the Oracle datasource. It's like my JobRepository definition isn't taken account.
What did I miss ?
EDIT: I'm using Spring Boot 1.5.3 and Spring Batch 3.0.7

With SpringBoot 2.x, the solution is simpler.
You have to extend the
DefaultBatchConfigurer
class like this:Without datasource, the framework automatically switches to use the
MapJobRepository
.
