混合顺序和并行分步处理

Question

我扩展了FlowJob类，并将其设置为：

final Flow subflow1 = new FlowBuilder<Flow>("subflow1")
    .start(new StepBuilder("SubFlow1-step")
            .chunk(1000)
            .reader(reader)
            .writer(writer)
            .repository(jobRepository)
            .transactionManager(txManager).build())
    .end();
final Flow subflow2 = new FlowBuilder<Flow>("subflow2")
    .start(new StepBuilder("SubFlow2-step")
            .chunk(1000)
            .reader(reader)
            .writer(writer)
            .taskExecutor(new SimpleAsyncTaskExecutor())
            .repository(jobRepository)
            .transactionManager(txManager).build())
    .end();

setFlow(new FlowBuilder<Flow>("Flow")
            .start(new StepBuilder("Flow-step1")
                    .chunk(10000)
                    .reader(reader)
                    .writer(writer)
                    .repository(jobRepository)
                    .transactionManager(txManager).build())
            .next(new StepBuilder("Flow-step2")
                    .tasklet(processor)
                    .repository(jobRepository)
                    .transactionManager(txManager).build())
            .split(new SimpleAsyncTaskExecutor())
            .add(subflow1, subflow2)
            .end());

如你所见，我想做的如下：

1. 执行步骤1

当我运行作业时，步骤1和2正确执行，然后作业终止。

知道吗？

编辑：SO Spring批处理流程/步骤后拆分的相关问题。

Answer 1

我相信这里面有个漏洞。目前的解决方法是使用拆分创建流程，并将流程添加到作业中，如下所示：

@Bean
public Job splitJob(@Qualifier("foo") Flow foo, @Qualifier("foo") Flow bar) {
    FlowBuilder<Flow> flowBuilder = new FlowBuilder<>("split");

    Flow flow = flowBuilder.split(new SimpleAsyncTaskExecutor())
            .add(foo, bar)
            .end();

    return jobBuilderFactory.get("splitJob")
            .start(myStep1())
            .next(myStep2())
            .on("COMPLETED").to(flow)
            .end()
            .build();
}
