如何将JobParameters传递给Spring Cloud Task发起的批处理作业？

@Autowired
private TaskLauncher taskLauncher;

public void launchBatchJob() {
    JobParameters jobParameters = new JobParametersBuilder()
            .addString("param1", "value1")
            .addLong("param2", 123L)
            .toJobParameters();

    taskLauncher.launch("myBatchJob", jobParameters);
}

@Configuration
@EnableBatchProcessing
public class BatchJobConfig {

    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Value("#{jobParameters['param1']}")
    private String param1;

    @Value("#{jobParameters['param2']}")
    private Long param2;

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

    @Bean
    public Step myStep() {
        return stepBuilderFactory.get("myStep")
                .tasklet((contribution, chunkContext) -> {
                    // 使用param1和param2进行批处理作业的逻辑处理
                    // ...
                    return RepeatStatus.FINISHED;
                })
                .build();
    }
}
