spring-batch

I'm having Standalone spring batch job. This works perfectly fine when in JUNIT @RunWith(SpringJUnit4ClassRunner.class) //@SpringApplicationConfiguration(classes = KPBootApplication.class) @ContextConfiguration(locations={"classpath:kp-sb.xml"}) public class KPBootApplicationTests { private final static Logger LOG=LoggerFactory.getLogger(KPBootApplicationTests.class); @Autowired ApplicationContext context; @Autowired private JobLauncher jobLauncher; @Autowired private Job job; @Test public void testJob() { final JobParameters jobParameters = new JobParametersBuilder() .toJobParameters();

ANSWER Based on the accepted answer code the following adjustment to that code worked for me: // helper method to create a split flow out of a List of steps private static Flow createParallelFlow(List<Step> steps) { SimpleAsyncTaskExecutor taskExecutor = new SimpleAsyncTaskExecutor(); taskExecutor.setConcurrencyLimit(steps.size()); Flow[] flows = new Flow[steps.size()]; for (int i = 0; i < steps.size(); i++) { flows[i] = new FlowBuilder<SimpleFlow>(steps.get(i).getName()).start(steps.get(i)).build(); } return new FlowBuilder<SimpleFlow>("parallelStepsFlow") .split(taskExecutor) .add(flows)

I'm trying to use Spring Batch 2.2.5 with Java config. Here is the config that I have: @Configuration @EnableBatchProcessing public class JobConfiguration { @Autowired private JobBuilderFactory jobBuilder; @Autowired private StepBuilderFactory stepBuilder; @Bean @Autowired public Job processDocumentsJob() { return jobBuilder.get("processDocumentsJob") .start(procesingStep()) .build(); } @Bean @Autowired public Step procesingStep() { CompositeItemProcessor<File, DocumentPackageFileMetadata> compositeProcessor = new CompositeItemProcessor<File, DocumentPackageFileMetadata>(); compositeProcessor

Our processor returns a List<?> (effectively passing a List<List<?>> ) to our ItemWriter . Now, we observed that the JdbcBatchItemWriter is not programmed to handle item instanceof List . We also observed to process item instanceof List ; we need to write a custom ItemSqlParameterSourceProvider . But the sad part is that it returns SqlParameterSource which can handle only one item and again not capable of handling a List . So, can someone help us understand how to handle list of lists in the JdbcBatchItemWriter ? Typically, the design pattern is: Reader -> reads something, returns ReadItem
