将Spring Batch XML转换为Java Config的Tasklet

Question

将spring boot batch XML转换为Java Config，尝试将以下代码更改为Java Config。

<batch:job id="batchJob1">
    <batch:step id="step">
        <batch:tasklet task-executor="taskExecutor" throttle-limit="${throttle.limit}">
            <batch:chunk reader="synchronizedProvisionReader"
                    processor="compositeItemProcessor" writer="subWriter"
                    commit-interval="${commit.interval}"
                             skip-limit="${skip.limit}"
                             retry-limit="${retry.limit}">
                <batch:retryable-exception-classes>
                    <batch:include class="org.springframework.dao.TransientDataAccessException"/>                           
                </batch:retryable-exception-classes>
                <batch:retry-listeners>
                    <batch:listener ref="batchRetryListener"/>
                </batch:retry-listeners>
                <batch:streams>
                    <batch:stream ref="fileItemReader" />                           
                </batch:streams>
                <batch:listeners>
                    <batch:listener ref="dateListener" />                           
                </batch:listeners>

            </batch:chunk>
        </batch:tasklet>
        <batch:listeners>
            <batch:listener ref="debugStepListener" />
            <batch:listener ref="skipCheckingListener"/>
        </batch:listeners>
    </batch:step>
    <batch:listeners>
        <batch:listener ref="batchProvisionJobListener" />
    </batch:listeners>
</batch:job>

我最初的尝试被tasklet卡住了，不知道如何为它配置tasklet。

@Configuration
@EnableBatchProcessing
public class BatchJob {

    @Autowired
    private JobBuilderFactory jobs;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Autowired
    @Qualifier("taskExecutor")
    private ThreadPoolTaskExecutor taskExecutor;

    @Value("${throttle.limit}")
    private int throttleLimit;


    @Bean
    public Job batchProvision(){
        return jobs.get("batchJob1").start(provisionStep()).build();
    }

    @Bean
    public Step step(){
        return stepBuilderFactory.get("provisionStep").tasklet();
    }             
}

请建议我如何在Java配置中设置与在XML中相同的任务
