A PartitionHandler which can send out step executions for remote processing and bring back the results.

Usage

From source file:org.springframework.batch.core.configuration.xml.StepParserStepFactoryBean.java

private void configurePartitionStep(PartitionStep ts) {
    Assert.state(partitioner != null, "A Partitioner must be provided for a partition step");
    configureAbstractStep(ts);// w  w  w  .j  a v  a2  s  .c o m

    if (partitionHandler != null) {
        ts.setPartitionHandler(partitionHandler);
    } else {
        TaskExecutorPartitionHandler partitionHandler = new TaskExecutorPartitionHandler();
        partitionHandler.setStep(step);
        if (taskExecutor == null) {
            taskExecutor = new SyncTaskExecutor();
        }
        partitionHandler.setGridSize(gridSize);
        partitionHandler.setTaskExecutor(taskExecutor);
        ts.setPartitionHandler(partitionHandler);
    }

    boolean allowStartIfComplete = this.allowStartIfComplete != null ? this.allowStartIfComplete : false;
    String name = this.name;
    if (step != null) {
        try {
            allowStartIfComplete = step.isAllowStartIfComplete();
            name = step.getName();
        } catch (Exception e) {
            logger.info("Ignored exception from step asking for name and allowStartIfComplete flag. "
                    + "Using default from enclosing PartitionStep (" + name + "," + allowStartIfComplete
                    + ").");
        }
    }
    SimpleStepExecutionSplitter splitter = new SimpleStepExecutionSplitter(jobRepository, allowStartIfComplete,
            name, partitioner);
