如何并行运行Spring批处理多个作业

Question

我是Spring批处理的新手，无法弄清楚该怎么做。

基本上我有一个春季批处理文件，两个文件都必须与diff调度程序时间并行执行，即一个批处理文件必须在 9AM 执行，而另一个批处理文件必须在 11AM 执行>如何实现此功能，请有人帮助我

我的代码在下面，但我遇到异常

BachFile1

@Configuration
@EnableBatchProcessing
public class BatchConfig {

    @Autowired
    private JobBuilderFactory jobs;

    @Autowired
    private StepBuilderFactory steps;

    @Bean
    public Step stepOne(){
        return steps.get("stepOne")
                .tasklet(new MyTaskOne())
                .build();
    }

    @Bean
    public Step stepTwo(){
        return steps.get("stepTwo")
                .tasklet(new MyTaskTwo())
                .build();
    }  

    @Bean
    public Job demoJob(){
        return jobs.get("exportUserJob1")
                .incrementer(new RunIdIncrementer())
                .start(stepOne())
                .next(stepTwo())
                .build();
    }
}

BatchFile2

                    }
                });
            }
        });

        return writer;
    }

    @Bean

                .writer(writer()).build();
    }

    @Bean
    public Job exportUserJob() {
        return jobBuilderFactory.get("exportUserJob2").incrementer(new RunIdIncrementer()).flow(step1()).end().build();
    }
