Spring batch -如何并行运行多个作业

@Configuration
@EnableBatchProcessing
public class BatchConfiguration {

    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Autowired
    private JobLauncher jobLauncher;

    @Autowired
    private TaskExecutor taskExecutor;

    @Bean
    public TaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
        taskExecutor.setMaxPoolSize(10); // 设置线程池大小
        return taskExecutor;
    }

    @Bean
    public Job job1() {
        return jobBuilderFactory.get("job1")
                .start(step1())
                .build();
    }

    @Bean
    public Step step1() {
        return stepBuilderFactory.get("step1")
                .tasklet((contribution, chunkContext) -> {
                    // 执行任务逻辑
                    return RepeatStatus.FINISHED;
                })
                .taskExecutor(taskExecutor) // 配置并行步骤的线程池
                .build();
    }

    // 配置其他作业和步骤...
