Usage

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

private void setUp() throws Exception {

    step = new TaskletStep("stepName");

    ResourcelessTransactionManager transactionManager = new ResourcelessTransactionManager();
    step.setTransactionManager(transactionManager);

    RepeatTemplate chunkTemplate = new RepeatTemplate();
    chunkTemplate.setCompletionPolicy(new SimpleCompletionPolicy(2));
    step.setTasklet(new TestingChunkOrientedTasklet<String>(new ListItemReader<String>(items), itemProcessor,
            itemWriter, chunkTemplate));

    jobRepository = new JobRepositorySupport();
    step.setJobRepository(jobRepository);

    TaskExecutorRepeatTemplate template = new TaskExecutorRepeatTemplate();
    template.setThrottleLimit(throttleLimit);
    SimpleAsyncTaskExecutor taskExecutor = new SimpleAsyncTaskExecutor();
    taskExecutor.setConcurrencyLimit(concurrencyLimit);
    template.setTaskExecutor(taskExecutor);
    step.setStepOperations(template);//  www.j a v  a2  s .  com
