Usage

From source file:org.springframework.batch.core.step.tasklet.AsyncChunkOrientedStepIntegrationTests.java

@Test
@Ignore//from   w w w. j a  v a2  s.c  o m
public void testStatus() throws Exception {

    step.setTasklet(new TestingChunkOrientedTasklet<String>(
            getReader(new String[] { "a", "b", "c", "a", "b", "c", "a", "b", "c", "a", "b", "c" }),
            new ItemWriter<String>() {
                @Override
                public void write(List<? extends String> data) throws Exception {
                    written.addAll(data);
                }
            }, chunkOperations));

    final JobExecution jobExecution = jobRepository.createJobExecution(job.getName(), new JobParameters(
            Collections.singletonMap("run.id", new JobParameter(getClass().getName() + ".1"))));
    StepExecution stepExecution = new StepExecution(step.getName(), jobExecution);

    jobRepository.add(stepExecution);
    step.execute(stepExecution);
    assertEquals(BatchStatus.COMPLETED, stepExecution.getStatus());
    // Need a transaction so one connection is enough to get job execution and its parameters
    StepExecution lastStepExecution = new TransactionTemplate(transactionManager)
            .execute(new TransactionCallback<StepExecution>() {
                @Override
                public StepExecution doInTransaction(TransactionStatus status) {
                    return jobRepository.getLastStepExecution(jobExecution.getJobInstance(), step.getName());
                }
