Spring / Spring batch Interview questions
Can we create Spring Batch Job without using XML configuration?
Spring 3 brought the ability to configure applications via java instead of XML. As of Spring Batch 2.2.0, batch jobs can be configured using the same java config. There are two components for the java based configuration: the @EnableBatchConfiguration annotation and two builders, JobBuilderFactory and the StepBuilderFactory.
@Configuration @EnableBatchProcessing @Import(DataSourceConfiguration.class) public class SimpleJobConfig { private static final String JOB_NAME = "DynamicJob"; @Autowired private JobBuilderFactory jobs; @Autowired private StepBuilderFactory steps; @Bean public Job job() throws Exception { SimpleJobBuilder jobBuilder = this.jobs.get(createJobName(JOB_NAME)).start(firstStep()); for ... { jobBuilder.next(createAStep( ... params ...)); } return standardJob.build(); } public Step createAStep(String name, ... needed parameters ...) throws Exception { StepBuilder stepBuilder = this.steps.get(name); return standardStep1.build(); } }
